945048ca36 alpha: fix the BUG() macro
The commit "alpha: teach the compiler that BUG doesn't return"
(ed6b9b97f42c091630335bfb71a2931e6f86388b) moved the asm code into inline
function which takes __FILE__ and __LINE__ as arguments.  This violates
asm constrains there ("i" - an immediate operand with constant value), so
that compile may result in warning or error, depending on compiler
version.

Just adding an infinite loop to the BUG() is sufficient.

e489a44e24 powerpc/5200: Bugfix for PCI mapping of memory and IMMR
This patch ensures that memory gets properly mapped into the PCI
address space.  Without this patch, the memory window BAR is left
at whatever value happened to be loaded into the BAR when Linux
was booted.  Without this patch, memory could end up getting mapped
at any of the 1G address boundaries instead of at '0' where Linux
expects it.

Similarly, this patch also ensures that the internally memory mapped
registers (IMMR) are mapped to the correct PCI address range.

Without this patch, PCI appears to work correctly until a PCI
device is inserted which DMAs into memory.

0dc23d7048 ARM: OMAP: fix fault in enter_full_retention()
In omap24xx_cpu_suspend assembly routine, the r2 register which holds
the address of the SDRC_POWER reg is set to zero before the value is
written back triggering a fault due to writing to address zero.

It's hard to tell where this change was introduced since this file
has been moved and merged.

While this fix prevents a crash, suspend on my n810 is broken with
current kernels.  I never come out of suspend.

5461af5af5 ARM: OMAP: Mask interrupts when disabling interrupts, v2
By Ingo Molnar, interrupts are not masked by default.
(refer to 76d2160147f43f982dfe881404cfde9fd0a9da21)

But if interrupts are not masked, the processor can wake up while in
Suspend-to-RAM state by an external interrupt. For example, if an
OMAP3 board is connected to Host PC by USB and entered to Suspend-to-RAM
state, it wake up automatically by M_IRQ_92. The disable_irq() function
can't disable the interrupt in H/W level, So I modified
arch/arm/mach-omap2/irq.c

df88acbbdc ARM: OMAP: gptimer min_delta_ns corrected
When 32 kHz timer is used the min_delta_ns should be initialized so
that it reflects the timer programming cost. A write to the timer
device will be usually posted, but it takes roughly 3 cycles before
it is effective. If the timer is reprogrammed before that, the CPU
will stall until the previous write completes. This was pointed out by
Richard Woodruff.

Since the lower bound for min_delta_ns is 1000, the change is visible
only with tick rates less than 3 MHz.

Also note that the old value is incorrect for 32 kHz also due to
a rounding error, and it can cause the timer queue to hang (due to
clockevent code trying to program the timer with zero ticks).

06151158f2 ARM: OMAP: Fix McBSP spin_lock deadlock
A spin_lock deadlock will occur when omap_mcbsp_request() is invoked.

omap_mcbsp_request()
\- clk_enable(mcbsp->clk)         [takes and holds clockfw_lock]
    \- omap2_clk_enable()
       \- _omap2_clk_enable()
           \- omap_mcbsp_clk_enable()
              \- clk_enable(child clock)   [tries for clockfw_lock again]

mcbsp_clk is a virtual clock and it comprises several child clocks. when
enable mcbsp_clk in omap_mcbsp_request(), the enable function of mcbsp_clk
will enable its child clocks, then the deadlock occurs.

The solution is to remove the virtual clock and enable these child clocks in
omap_mcbsp_request() directly.

08e445bd6a [ARM] 5366/1: fix shared memory coherency with VIVT L1 + L2 caches
When there are multiple L1-aliasing userland mappings of the same physical
page, we currently remap each of them uncached, to prevent VIVT cache
aliasing issues. (E.g. writes to one of the mappings not being immediately
visible via another mapping.)  However, when we do this remapping, there
could still be stale data in the L2 cache, and an uncached mapping might
bypass L2 and go straight to RAM.  This would cause reads from such
mappings to see old data (until the dirty L2 line is eventually evicted.)

This issue is solved by forcing a L2 cache flush whenever the shared page
is made L1 uncacheable.

Ideally, we would make L1 uncacheable and L2 cacheable as L2 is PIPT. But
Feroceon does not support that combination, and the TEX=5 C=0 B=0 encoding
for XSc3 doesn't appear to work in practice.

69b052e828 powerpc/pseries: Correct VIO bus accounting problem in CMO env.
In the VIO bus code the wrappers for dma alloc_coherent and free_coherent
calls are rounding to IOMMU_PAGE_SIZE.  Taking a look at the underlying
calls, the actual mapping is promoted to PAGE_SIZE.  Changing the
rounding in these two functions fixes under-reporting the entitlement
used by the system.  Without this change, the system could run out of
entitlement before it believes it has and incur mapping failures at the
firmware level.

Also in the VIO bus code, the wrapper for dma map_sg is not exiting in
an error path where it should.  Rather than fall through to code for the
success case, this patch adds the return that is needed in the error path.

e0212e7218 m68knommu: set NO_DMA

not provide the required functions, resulting in the following
build error triggered by commit a40c24a13366e324bc0ff8c3bb107db89312c984

a1a9bcb503 m68knommu: fix cache flushing for the 527x ColdFire processors
Fix cache flushing for the 527x ColdFire processors
Its CACR register format is slightly different.

Along with this add support for flushing the 523x cache, which uses
the same format as the 527x ColdFire's, and was missing flush support.

c7bcd0df1f m68knommu: use one exist from execption
Part of the code that did not make sense to me got removed by Greg.
This is part two:

The first compare is to check whether the interrupts are disabled or not.
Depending on the result we exectute the RESTORE_ALL macro is not only
restoring the stack but also returning to caller.
The test for pending softirq has been removed because it is allready done
in irq_exit().
Since system_call() is allso using the SAVE_ALL macro and returning via
ret_from_exception label I see no reason why we could not do this here
as well. This is also handy because if we return from the timer interrupt
and we need to resched than we check for this :)
