In checkin
5551a34e5a x86-64, build: Always pass in -mno-sse
we unconditionally added -mno-sse to the main build, to keep newer
compilers from generating SSE instructions from autovectorization.
However, this did not extend to the special environments
(arch/x86/boot, arch/x86/boot/compressed, and arch/x86/realmode/rm).
Add -mno-sse to the compiler command line for these environments, and
add -mno-mmx to all the environments as well, as we don't want a
compiler to generate MMX code either.
This patch also removes a $(cc-option) call for -m32, since we have
long since stopped supporting compilers too old for the -m32 option,
and in fact hardcode it in other places in the Makefiles.

get_wchan() is lockless. Task may wakeup at any time and change its own stack,
thus each next stack frame may be overwritten and filled with random stuff.
/proc/$pid/stack interface had been disabled for non-current tasks, see [1]
But 'wchan' still allows to trigger stack frame unwinding on volatile stack.
This patch fixes oops in unwind_frame() by adding stack pointer validation on
each step (as x86 code do), unwind_frame() already checks frame pointer.
Also I've found another report of this oops on stackoverflow (irony).

Peter reports that OMAP audio broke with the recent fix for these
checks, caused by OMAP audio using a 64-bit DMA mask. We should
allow 64-bit DMA masks even with 32-bit dma_addr_t if we can be sure
the amount of RAM we have won't allow the 32-bit dma_addr_t to
overflow. Unfortunately, the checks to detect overflow were not
correct.

When not aggregating packets, fi->framelen should be passed in as length
to calculate the duration. Before the tx path rework, ath_tx_fill_desc
was called for either one aggregate, or one single frame, with the
length of the packet or the aggregate as a parameter.
After the rework, ath_tx_sched_aggr can pass a burst of single frames to
ath_tx_fill_desc and sets len=0.
Fix broken duration calculation by overriding the length in ath_tx_fill_desc
before passing it to ath_buf_set_rate.

missing braces, however, we just set return result if clk_get fail

Unlike what the comment states, errata i660 does not state that we
can't RESET the USB host module. Instead it states that RESET is the
only way to recover from a deadlock situation.
RESET ensures that the module is in a known good state irrespective
of what bootloader does with the module, so it must be done at boot.

In _ocp_softreset(), after _set_softreset() + write_sysconfig(),
the hwmod's sysc_cache will always contain SOFTRESET bit set
so all further writes to sysconfig using this cache will initiate
a repeated SOFTRESET e.g. enable_sysc(). This is true for OMAP3 like
platforms that have RESET_DONE status in the SYSSTATUS register and
so the the SOFTRESET bit in SYSCONFIG is not automatically cleared.
It is not a problem for OMAP4 like platforms that indicate RESET
completion by clearing the SOFTRESET bit in the SYSCONFIG register.
This repeated SOFTRESET is undesired and was the root cause of
USB host issues on OMAP3 platforms when hwmod was allowed to do the
SOFTRESET for the USB Host module.
To fix this we clear the SOFTRESET bit and update the sysconfig
register + sysc_cache using write_sysconfig().

When we use perf kvm record-report, there is a bug in report subcommand.
Example:
# perf kvm stat record -a sleep 1

[ perf record: Captured and wrote 0.678 MB perf.data.guest (~29641 samples) ]
# perf kvm stat report
failed to open perf.data: No such file or directory (try 'perf record' first)

This bug was introduced by f5fc14124.
+ struct perf_data_file file = {

+ .mode = PERF_DATA_MODE_READ,

kvm->tool = eops;
- kvm->session = perf_session__new(kvm->file_name, O_RDONLY, 0, false,

+ kvm->session = perf_session__new(&file, false, &kvm->tool);
It changed the path from kvm->file_name to input_name, this patch change the path back to

Pull drm fixes from Dave Airlie:
"This is probably a bit big, but just because I fell behind last week
and didn't get to doing any pulls, so stuff backed up behind me, I

If SHARK_USE_LEDS=1, but CONFIG_PM=n:

Instead of making the #ifdef logic even more complicated (there are already
two definitions of shark_resume_leds()), mark shark_resume_leds() inline to
kill the compiler warning. shark_resume_leds() is small and it has only one

Fix kernel warning and failure to register sensor hub devices with MFD. Now
many devices has in-built sensor hubs. So by default this HID hub, is properly
parsed and register individual sensors as platform device using MFD framework.
But if a second sensor hub is attached via USB, which has same sensors, it will
result in kernel warning and failure to register MFD cell as the platform
device sysfs file name will be same as created by in-built sensor hubs. This
patch sets MFD cell id to PLATFORM_DEVID_AUTO. In this way there will never be
duplicate sysfs file names.

Without this, the USB devices are sometimes not detected on OMAP4 Panda
with u-boot v2013.10.
Unlike what the comment states, errata i660 does not state that we
can't RESET the USB host module. Instead it states that RESET is the
only way to recover from a deadlock situation.
RESET ensures that the module is in a known good state irrespective
of what bootloader does with the module, so it must be done at boot.
