Add support to debug S3 early resume by flashing the keyboard
LEDs three times in the realmode path. This is useful to allow
one to determine if S3 hangs occur in the BIOS or during the early
resume phase.
Add kernel parameter acpi_sleep=s3_leds to enable the s3 debugging
option. This can also be enabled by writing 8 to
/proc/sys/kernel/acpi_video_flags.

This patch never will be accepted upstream because the WARN_ON
is supposed to perevent driver development which is only
compatible with x86 on x86 (ARM can sleep in that function).
The right way to fix it would be to make the offending function
use locks in the right way but that requires careful implementation.

commit c773f70fd6b53ee646727f871833e53649907264 upstream (linux-2.6-tip)
Xeon 75xx doesn't log physical addresses on corrected machine check
events in the standard architectural MSRs. Instead the address has to
be retrieved in a model specific way. This makes it impossible to do
predictive failure analysis.
Implement cpu model specific code to do this in mce-xeon75xx.c using a
new hook that is called from the generic poll code. The code retrieves
the physical address/DIMM of the last corrected error from the
platform and makes the address look like a standard architectural MCA
address for further processing.
In addition the DIMM information is retrieved and put into two new
aux0/aux1 fields in struct mce. These fields are specific to a given
CPU. These fields can then be decoded by mcelog into specific DIMM
information. The latest mcelog version has support for this.
Longer term this will be likely in a different output format, but
short term that seemed like the least intrusive solution. Older mcelog
can deal with an extended record.
There's no code to print this information on a panic because this only
works for corrected errors, and corrected errors do not usually result
in panics.
The act of retrieving the DIMM/PA information can take some time, so
this code has a rate limit to avoid taking too much CPU time on a
error flood.
The whole thing can be loaded as a module and has suitable PCI-IDs so
that it can be auto-loaded by a distribution. The code also checks
explicitely for the expected CPU model number to make sure this code
doesn't run anywhere else.

tile: fix bug in get_user() for 4-byte values
|
|
The definition of 32-bit values in the 64-bit tilegx architecture is that
they should be sign-extended regardless of whether they are considered
signed or unsigned by the compiler. Accordingly, we need to use an
"ld4s" rather than "ld4u" to load and sign-extend for get_user().
This fixes glibc bug 14238 (see http://sourceware.org/bugzilla),
introduced during the 3.5 merge window.

- When booting on machines with SR-IOV PCI bridge we didn't check for the bridge
and tried to use it.
- Under AMD machines would advertise the APERFMPERF resulting in needless amount
of MSRs from the guest.
- A global value (xen_released_pages) was not subtracted at bootup when pages
were added back in. This resulted in the balloon worker having the wrong
account of how many pages were truly released.

At present, hard_irq_disable() does nothing on powerpc because of
this code in include/linux/interrupt.h:
#ifndef hard_irq_disable
#define hard_irq_disable() do { } while(0)
#endif
So we need to make our hard_irq_disable be a macro. It was previously
a macro until commit 7230c56441 ("powerpc: Rework lazy-interrupt
handling") changed it to a static inline function.

When the frontend and the backend reside on the same domain, even if we
add pages to the m2p_override, these pages will never be returned by
mfn_to_pfn because the check "get_phys_to_machine(pfn) != mfn" will
always fail, so the pfn of the frontend will be returned instead
(resulting in a deadlock because the frontend pages are already locked).

[<ffffffff81a18d69>] system_call_fastpath+0x16/0x1b
The explanation is in the comment within the code:
We need to do this because the pages shared by the frontend
(xen-blkfront) can be already locked (lock_page, called by
do_read_cache_page); when the userspace backend tries to use them
with direct_IO, mfn_to_pfn returns the pfn of the frontend, so
do_blockdev_direct_IO is going to try to lock the same pages
again resulting in a deadlock.
A simplified call graph looks like this:
pygrub QEMU
-----------------------------------------------
do_read_cache_page io_submit
| |
lock_page ext3_direct_IO
|
bio_add_page
|
lock_page
Internally the xen-blkback uses m2p_add_override to swizzle (temporarily)
a 'struct page' to have a different MFN (so that it can point to another
guest). It also can easily find out whether another pfn corresponding
to the mfn exists in the m2p, and can set the FOREIGN bit
in the p2m, making sure that mfn_to_pfn returns the pfn of the backend.
This allows the backend to perform direct_IO on these pages, but as a
side effect prevents the frontend from using get_user_pages_fast on
them while they are being shared with the backend.

I noticed that the LBR fixups were not working anymore
on programs where they used to. I tracked this down to
a recent change to copy_from_user_nmi():
db0dc75d640 ("perf/x86: Check user address explicitly in copy_from_user_nmi()")
This commit added a call to __range_not_ok() to the
copy_from_user_nmi() routine. The problem is that the logic
of the test must be reversed. __range_not_ok() returns 0 if the
range is VALID. We want to return early from copy_from_user_nmi()
if the range is NOT valid.

The warning below triggers on AMD MCM packages because physical package
IDs on the cores of a _physical_ socket are the same. I.e., this field
says which CPUs belong to the same physical package.
However, the same two CPUs belong to two different internal, i.e.
"logical" nodes in the same physical socket which is reflected in the
CPU-to-node map on x86 with NUMA.
Which makes this check wrong on the above topologies so circumvent it.

CPU offline path calls the hrtimer interrupt handler with interrupts
disabled, without touching preempt_count, triggering this warning.
Remove the warning since it is supposed to be used from hrtimer
interrupt context only.

The assembler entry code calls directly to the syscall_trace_enter() and
syscall_trace_leave() functions. But currently they are conditionaly
compiled out for the non-MMU classic m68k CPU types (so 68328 for example),
resulting in a link error:
LD vmlinux
arch/m68k/platform/68328/built-in.o: In function `do_trace':
(.text+0x1c): undefined reference to `syscall_trace_enter'
arch/m68k/platform/68328/built-in.o: In function `do_trace':
(.text+0x4c): undefined reference to `syscall_trace_leave'
Change the conditional check that includes these functions to be true for
the !defined(CONFIG_MMU) case as well.

Compiling for 68360 based targets fails with:
arch/m68k/platform/68360/config.c: In function ‘hw_tick’:
arch/m68k/platform/68360/config.c:55:2: error: implicit declaration of function ‘arch_timer_interrupt’
arch/m68k/platform/68360/config.c: At top level:

arch/m68k/include/asm/machdep.h:36:13: note: previous declaration of ‘hw_timer_init’ was here
Changes made to hw_timer_init() didn't get updated in the 68328 timer code.
So process and call the "handler" arg that is now passed into that
hw_timer_init() function.

When building for non-MMU based classic 68k CPU types (like the 68328 for
example) you get a compilation error:
CC arch/m68k/kernel/time.o
arch/m68k/kernel/time.c:91:5: error: redefinition of ‘arch_gettimeoffset’
include/linux/time.h:145:19: note: previous definition of ‘arch_gettimeoffset’ was here
The arch_gettimeoffset() code is included when building for these CPU types,
but it shouldn't be. Those machine types do not have
CONFIG_ARCH_USES_GETTIMEOFFSET set.
The fix is simply to conditionally include the arch_gettimeoffset() code on
that same config setting that specifies its use or not.

Nothing includes these two headers. None of the macros they define are
used anywhere in the tree. This was also the case in v2.6.12-rc2 and,
presumably, every release in between. These two headers can safely be
removed.

arm_dma_limit stores physical address of maximal address accessible by DMA,
so the phys_addr_t type makes much more sense for it instead of u32. This
