191aee58b6 powerpc: Remove IOMMU_VMERGE config option
The description says:

 Cause IO segments sent to a device for DMA to be merged virtually
 by the IOMMU when they happen to have been allocated contiguously.
 This doesn't add pressure to the IOMMU allocator. However, some
 drivers don't support getting large merged segments coming back
 from *_map_sg().

 Most drivers don't have this problem; it is safe to say Y here.

It's out of date. Long ago, drivers didn't have a way to tell IOMMUs
about their segment length limit (that is, the maximum segment length
that they can handle). So IOMMUs merged as many segments as possible
and gave too large segments to drivers.

dma_get_max_seg_size() was introduced to solve the above
problem. Device drives can use the API to tell IOMMU about the maximum
segment length that they can handle. In addition, the default limit
(64K) should be safe for everyone.

So this config option seems to be unnecessary.

Note that this config option just enables users to disable the virtual
merging by default. Users can still disable the virtual merging by the
boot parameter.

a93272969c powerpc: Fix swiotlb to respect the boot option
powerpc initializes swiotlb before parsing the kernel boot options so
swiotlb options (e.g. specifying the swiotlb buffer size) are ignored.

Any time before freeing bootmem works for swiotlb so this patch moves
powerpc's swiotlb initialization after parsing the kernel boot
options, mem_init (as x86 does).

The powerpc implementations of syscall_get_error and

and setting syscall error status.  Fortunately these APIs don't seem

f34edbc1cd perf, x86: Add a key to simplify template lookup in Pentium-4 PMU
Currently, we use opcode(Event and Event-Selector) + emask to
look up template in p4_templates.

But cache events (L1-dcache-load-misses, LLC-load-misses, etc)
use the same event(P4_REPLAY_EVENT) to do the counting, ie, they
have the same opcode and emask. So we can not use current lookup
mechanism to find the template for cache events.

This patch introduces a "key", which is the index into
p4_templates. The low 12 bits of CCCR are reserved, so we can
hide the "key" in the low 12 bits of hwc->config.

We extract the key from hwc->config and then quickly find the
template.

dcd5c1662d perf: Fix unexported generic perf_arch_fetch_caller_regs
perf_arch_fetch_caller_regs() is exported for the overriden x86
version, but not for the generic weak version.

As a general rule, weak functions should not have their symbol
exported in the same file they are defined.

So let's export it on trace_event_perf.c as it is used by trace
events only.

This fixes:

	ERROR: ".perf_arch_fetch_caller_regs" [fs/xfs/xfs.ko] undefined!
	ERROR: ".perf_arch_fetch_caller_regs" [arch/powerpc/platforms/cell/spufs/spufs.ko] undefined!

984763cb90 perf, x86: Report error code that returned from x86_pmu.hw_config()
If x86_pmu.hw_config() fails a fixed error code (-EOPNOTSUPP) is
returned even if a different error was reported. This patch fixes
this.

9d296cfa69 powerpc/fsl-booke: Get coherent bit from PTE
We shouldn't be always setting 'M' in the TLB entry since its reasonable
for somethings to be mapped non-coherent.  The PTE should have 'M' set
properly.

d6ccb1f55d powerpc/85xx: Make sure lwarx hint isn't set on ppc32
e500v1/v2 based chips will treat any reserved field being set in an

a bad idea.

Anton should be kept away from the powerpc opcode map.

1d199b1ad6 perf: Fix unexported generic perf_arch_fetch_caller_regs
perf_arch_fetch_caller_regs() is exported for the overriden x86
version, but not for the generic weak version.

As a general rule, weak functions should not have their symbol
exported in the same file they are defined.

So let's export it on trace_event_perf.c as it is used by trace
events only.

This fixes:

	ERROR: ".perf_arch_fetch_caller_regs" [fs/xfs/xfs.ko] undefined!
	ERROR: ".perf_arch_fetch_caller_regs" [arch/powerpc/platforms/cell/spufs/spufs.ko] undefined!

-v2: And also only build it if trace events are enabled.
-v3: Fix changelog mistake

e449526282 perf, x86: Enable not tagged retired instruction counting on P4s
This should turn on instruction counting on P4s, which was missing in
the first version of the new PMU driver.

It's inaccurate for now, we still need dependant event to tag mops
before we can count them precisely. The result is that the number of
instruction may be lifted up.
