ARM64: enable GENERIC_FIND_FIRST_BIT
ARM64 doesn't implement find_first_{zero}_bit in arch code and doesn't
enable it in a config. It leads to using find_next_bit() which is less
efficient:

Enabling find_{first,next}_bit() would also benefit for_each_{set,clear}_bit().
On A-53 find_first_bit() is almost twice faster than find_next_bit(), according
to lib/find_bit_benchmark (thanks to Alexey for testing):
GENERIC_FIND_FIRST_BIT=n:
[7126084.948181] find_first_bit: 47389224 ns, 16357 iterations
[7126085.032315] find_first_bit: 19048193 ns, 655 iterations
GENERIC_FIND_FIRST_BIT=y:
[ 84.158068] find_first_bit: 27193319 ns, 16406 iterations
[ 84.233005] find_first_bit: 11082437 ns, 656 iterations
GENERIC_FIND_FIRST_BIT=n bloats the kernel despite that it disables generation
of find_{first,next}_bit():
yury:linux$ scripts/bloat-o-meter vmlinux vmlinux.ffb
add/remove: 4/1 grow/shrink: 19/251 up/down: 564/-1692 (-1128)
...
Overall, GENERIC_FIND_FIRST_BIT=n is harmful both in terms of performance and
code size, and it's better to have GENERIC_FIND_FIRST_BIT enabled.

arm64 provides always working implementation of futex_atomic_cmpxchg_inatomic(), so there is no need to check it runtime.

arm64: Select ARCH_HAS_FAST_MULTIPLIER
It is probably safe to assume that all Armv8-A implementations have a multiplier whose efficiency is comparable or better than a sequence of three or so register-dependent arithmetic instructions. Select ARCH_HAS_FAST_MULTIPLIER to get ever-so-slightly nicer codegen in the few dusty old corners which care. In a contrived benchmark calling hweight64() in a loop, this does indeed turn out to be a small win overall, with no measurable impact on Cortex-A57 but about 5% performance improvement on Cortex-A53.

arm64/kernel: jump_label: Switch to relative references
On a randomly chosen distro kernel build for arm64, vmlinux.o shows the
following sections, containing jump label entries, and the associated
RELA relocation records, respectively:
...
[38088] __jump_table PROGBITS 0000000000000000 00e19f30
000000000002ea10 0000000000000000 WA 0 0 8
[38089] .rela__jump_table RELA 0000000000000000 01fd8bb0
000000000008be30 0000000000000018 I 38178 38088 8
...
In other words, we have 190 KB worth of 'struct jump_entry' instances,
and 573 KB worth of RELA entries to relocate each entry's code, target
and key members. This means the RELA section occupies 10% of the .init
segment, and the two sections combined represent 5% of vmlinux's entire
memory footprint.
So let's switch from 64-bit absolute references to 32-bit relative
references for the code and target field, and a 64-bit relative
reference for the 'key' field (which may reside in another module or the
core kernel, which may be more than 4 GB way on arm64 when running with
KASLR enable): this reduces the size of the __jump_table by 33%, and
gets rid of the RELA section entirely.

mm: speed up mremap by 20x on large regions
Android needs to mremap large regions of memory during memory management related operations. The mremap system call can be really slow if THP is not enabled. The bottleneck is move_page_tables, which is copying each pte at a time, and can be really slow across a large map. Turning on THP may not be a viable option, and is not for us. This patch speeds up the performance for non-THP system by copying at the PMD level when possible. The speedup is an order of magnitude on x86 (~20x). On a 1GB mremap, the mremap completion times drops from 3.4-3.6 milliseconds to 144-160 microseconds. Before: Total mremap time for 1GB data: 3521942 nanoseconds. Total mremap time for 1GB data: 3449229 nanoseconds. Total mremap time for 1GB data: 3488230 nanoseconds. After: Total mremap time for 1GB data: 150279 nanoseconds. Total mremap time for 1GB data: 144665 nanoseconds. Total mremap time for 1GB data: 158708 nanoseconds. If THP is enabled the optimization is mostly skipped except in certain situations.

arm64: Select ARCH_HAS_FAST_MULTIPLIER
It is probably safe to assume that all Armv8-A implementations have a multiplier whose efficiency is comparable or better than a sequence of three or so register-dependent arithmetic instructions. Select ARCH_HAS_FAST_MULTIPLIER to get ever-so-slightly nicer codegen in the few dusty old corners which care. In a contrived benchmark calling hweight64() in a loop, this does indeed turn out to be a small win overall, with no measurable impact on Cortex-A57 but about 5% performance improvement on Cortex-A53.

arm64: Mitigate spectre style branch history side channels
commit 558c303c9734af5a813739cd284879227f7297d2 upstream. Speculation attacks against some high-performance processors can make use of branch history to influence future speculation. When taking an exception from user-space, a sequence of branches or a firmware call overwrites or invalidates the branch history. The sequence of branches is added to the vectors, and should appear before the first indirect branch. For systems using KPTI the sequence is added to the kpti trampoline where it has a free register as the exit from the trampoline is via a 'ret'. For systems not using KPTI, the same register tricks are used to free up a register in the vectors. For the firmware call, arch-workaround-3 clobbers 4 registers, so there is no choice but to save them to the EL1 stack. This only happens for entry from EL0, so if we take an exception due to the stack access, it will not become re-entrant. For KVM, the existing branch-predictor-hardening vectors are used. When a spectre version of these vectors is in use, the firmware call is sufficient to mitigate against Spectre-BHB. For the non-spectre versions, the sequence of branches is added to the indirect vector.

arm64_1188873_read_cntvct_el0() is protected by the correct
CONFIG_ARM64_ERRATUM_1188873 #ifdef, but the only reference to it is
also inside of an CONFIG_ARM_ARCH_TIMER_OOL_WORKAROUND section,
and causes a warning if that is disabled:
drivers/clocksource/arm_arch_timer.c:323:20: error: 'arm64_1188873_read_cntvct_el0' defined but not used [-Werror=unused-function]
Since the erratum requires that we always apply the workaround
in the timer driver, select that symbol as we do for SoC
specific errata.

arm64: arch_timer: Add workaround for ARM erratum 1188873
commit 95b861a4a6d94f64d5242605569218160ebacdbe upstream. When running on Cortex-A76, a timer access from an AArch32 EL0 task may end up with a corrupted value or register. The workaround for this is to trap these accesses at EL1/EL2 and execute them there. This only affects versions r0p0, r1p0 and r2p0 of the CPU.

FROMLIST: arm64: kernel: Implement fast refcount checking
This adds support to arm64 for fast refcount checking, as contributed
by Kees for x86 based on the implementation by grsecurity/PaX.
The general approach is identical: the existing atomic_t helpers are
cloned for refcount_t, with the arithmetic instruction modified to set
the PSTATE flags, and one or two branch instructions added that jump to
an out of line handler if overflow, decrement to zero or increment from
zero are detected.
One complication that we have to deal with on arm64 is the fact that
it has two atomics implementations: the original LL/SC implementation
using load/store exclusive loops, and the newer LSE one that does mostly
the same in a single instruction. So we need to clone some parts of
both for the refcount handlers, but we also need to deal with the way
LSE builds fall back to LL/SC at runtime if the hardware does not
support it.
As is the case with the x86 version, the performance gain is substantial
(ThunderX2 @ 2.2 GHz, using LSE), even though the arm64 implementation
incorporates an add-from-zero check as well:
perf stat -B -- echo ATOMIC_TIMING >/sys/kernel/debug/provoke-crash/DIRECT
116252672661 cycles # 2.207 GHz
52.689793525 seconds time elapsed
perf stat -B -- echo REFCOUNT_TIMING >/sys/kernel/debug/provoke-crash/DIRECT
127060259162 cycles # 2.207 GHz
57.243690077 seconds time elapsed
For comparison, the numbers below were captured using CONFIG_REFCOUNT_FULL,
which uses the validation routines implemented in C using cmpxchg():
perf stat -B -- echo REFCOUNT_TIMING >/sys/kernel/debug/provoke-crash/DIRECT
Performance counter stats for 'cat /dev/fd/63':
191057942484 cycles # 2.207 GHz
86.568269904 seconds time elapsed
As a bonus, this code has been found to perform significantly better on
systems with many CPUs, due to the fact that it no longer relies on the
load/compare-and-swap combo performed in a tight loop, which is what we
emit for cmpxchg() on arm64.

FROMLIST: BACKPORT: [PATCH 6/6] arm64: Wire up and expose the new compat vDSO
(cherry pick from url https://patchwork.kernel.org/patch/10060447/) Expose the new compat vDSO via the COMPAT_VDSO config option. The option is not enabled in defconfig because we really need a 32-bit compiler this time, and we rely on the user to provide it themselves by setting CROSS_COMPILE_ARM32. Therefore enabling the option by default would make little sense, since the user must explicitly set a non-standard environment variable anyway. CONFIG_COMPAT_VDSO is not directly used in the code, because we want to ignore it (build as if it were not set) if the user didn't set CROSS_COMPILE_ARM32. If the variable has been set to a valid prefix, CONFIG_VDSO32 will be set; this is the option that the code and Makefiles test. For more flexibility, like CROSS_COMPILE, CROSS_COMPILE_ARM32 can also be set via CONFIG_CROSS_COMPILE_ARM32 (the environment variable overrides the config option, as expected).

FROMLIST: [PATCH v3 3/3] arm64: compat: Add CONFIG_KUSER_HELPERS
(cherry picked from url http://lkml.iu.edu/hypermail/linux/kernel/1709.1/01903.html) Make it possible to disable the kuser helpers by adding a KUSER_HELPERS config option (enabled by default). When disabled, all kuser helpers-related code is removed from the kernel and no mapping is done at the fixed high address (0xffff0000); any attempt to use a kuser helper from a 32-bit process will result in a segfault.

arm64: Extend workaround for erratum 1024718 to all versions of Cortex-A55
commit c0b15c25d25171db4b70cc0b7dbc1130ee94017d upstream. The erratum 1024718 affects Cortex-A55 r0p0 to r2p0. However we apply the work around for r0p0 - r1p0. Unfortunately this won't be fixed for the future revisions for the CPU. Thus extend the work around for all versions of A55, to cover for r2p0 and any future revisions.

Extra added fixes in fs/f2fs/data.c for FBE:
* Fix FBE regression with 9937c21ce1 ("f2fs: add bio cache
for IPU"). The above commit is not setting the DUN for
bio, due to which the bio's could get corrupted when FBE
is enabled.
* The f2fs_merge_page_bio() incorrectly uses the bio after
it is submitted for IO when fscrypt_mergeable_bio()
returns false. Fix it by making the submitted bio NULL
so that a new bio gets allocated for the next/new page.

FROMLIST: arm64: disable function graph tracing with SCS
The graph tracer hooks returns by modifying frame records on the (regular) stack, but with SCS the return address is taken from the shadow stack, and the value in the frame record has no effect. As we don't currently have a mechanism to determine the corresponding slot on the shadow stack (and to pass this through the ftrace infrastructure), for now let's disable the graph tracer when SCS is enabled.

clk: msm: Add snapshot of clock framework files
This is snapshot of the clock framework files as of msm-4.9
'commit cc7a1542d987 ("msm: ipa: Fix assignment warning with clang").
Below is the brief description of the additional changes made:
1. Add COMMON_CLK_MSM config flag for conditional compilation for
some common files used between COMMON_CLK_MSM and COMMON_CLK_QCOM
clock framework files.
2. Add reset controller framework files for BCR operation.
3. Add conditional compilation support for FTRACE clock functions
to maintain compatibility for clock framework based on
COMMON_CLK_MSM and COMMON_CLK_QCOM.
4. Add files for GDSC operation.
5. Add BCR reset maps.
6. Resolve compilation issue for qti-quin-gvm.
Some PLL HWs require an additional delay for the PLL lock detect
to stabilize after being brought out of reset and SW to poll for
lock detect status. Add delay of 50uSec before polling lock_det
bit by introducing new pll ops.
Also if PLL fails to lock, record additional PLL debug information
in the kernel log before panic().
'commit 90cb5ecd7cfd ("clk: msm: Add delay of 50uSec before polling
lock_detect status")'.
1:1 is the MN divider preference for DSI PCLK for the regular
24 bpp use-case for display as per hardware recommendation.
Update the divider array to give first priority to 1:1
divider combination.
'commit a270c07a1e21 ("clk: msm: update the fractional divider
array for DSI PCLK")'.
For some PLLs, there could be need to configure the calibration
L value for auto calibration which PLL would use whenever it will
come out of reset. Add support for the same by writing into
USER_CTL_HI register.
'commit 05bd8759e347 ("clk: msm: Add support to configure
calibration L value")'.

BACKPORT: arm64: Introduce prctl() options to control the tagged user addresses ABI
(Upstream commit 63f0c60379650d82250f22e4cf4137ef3dc4f43d). It is not desirable to relax the ABI to allow tagged user addresses into the kernel indiscriminately. This patch introduces a prctl() interface for enabling or disabling the tagged ABI with a global sysctl control for preventing applications from enabling the relaxed ABI (meant for testing user-space prctl() return error checking without reconfiguring the kernel). The ABI properties are inherited by threads of the same application and fork()'ed children but cleared on execve(). A Kconfig option allows the overall disabling of the relaxed ABI. The PR_SET_TAGGED_ADDR_CTRL will be expanded in the future to handle MTE-specific settings like imprecise vs precise exceptions.

BACKPORT: arm64: Add support for relocating the kernel with RELR relocations
RELR is a relocation packing format for relative relocations. The format is described in a generic-abi proposal: https://groups.google.com/d/topic/generic-abi/bX460iggiKg/discussion The LLD linker can be instructed to pack relocations in the RELR format by passing the flag --pack-dyn-relocs=relr. This patch adds a new config option, CONFIG_RELR. Enabling this option instructs the linker to pack vmlinux's relative relocations in the RELR format, and causes the kernel to apply the relocations at startup along with the RELA relocations. RELA relocations still need to be applied because the linker will emit RELA relative relocations if they are unrepresentable in the RELR format (i.e. address not a multiple of 2). Enabling CONFIG_RELR reduces the size of a defconfig kernel image with CONFIG_RANDOMIZE_BASE by 3.5MB/16% uncompressed, or 550KB/5% compressed (lz4).

arm64: arch_timer: Add workaround for ARM erratum 1188873
When running on Cortex-A76, a timer access from an AArch32 EL0 task may end up with a corrupted value or register. The workaround for this is to trap these accesses at EL1/EL2 and execute them there. This only affects versions r0p0, r1p0 and r2p0 of the CPU.

UPSTREAM: arm64/mm/kasan: don't use vmemmap_populate() to initialize shadow
Upstream commit e17d8025f07e4fd9d73b137a8bcab04548126b83. The kasan shadow is currently mapped using vmemmap_populate() since that provides a semi-convenient way to map pages into init_top_pgt. However, since that no longer zeroes the mapped pages, it is not suitable for kasan, which requires zeroed shadow memory. Add kasan_populate_shadow() interface and use it instead of vmemmap_populate(). Besides, this allows us to take advantage of gigantic pages and use them to populate the shadow, which should save us some memory wasted on page tables and reduce TLB pressure.

On the affected Cortex-A76 cores (r0p0 to r3p0), if a virtual address for a cacheable mapping of a location is being accessed by a core while another core is remapping the virtual address to a new physical page using the recommended break-before-make sequence, then under very rare circumstances TLBI+DSB completes before a read using the translation being invalidated has been observed by other observers. The workaround repeats the TLBI+DSB operation and is shared with the Qualcomm Falkor erratum 1009.
