commit e78e5a91456fcecaa2efbb3706572fe043766f4d upstream.
In the __getcpu function, lsl is using the wrong target and destination
registers. Luckily, the compiler tends to choose %eax for both variables,
so it has been working so far.

On Intel it is required to do CPUID(1) before reading the microcode
revision MSR. Current code in 4.4 an 4.9 relies on sync_core() to call
CPUID, unfortunately on 32 bit machines code inside sync_core() always
jumps past CPUID instruction as it depends on data structure boot_cpu_data
witch are not populated correctly so early in boot sequence.
It depends on:

commit 49c64df880570034308e4a9a49c4bc95cf8cdb33 upstream.
The variable 'name' is released multiple times in the error path,
which may cause double free issues.
This problem is avoided by adding a goto label to release the memory
uniformly. And this change also makes the code a bit more cleaner.

commit 80c503e0e68fbe271680ab48f0fe29bc034b01b7 upstream.
The __torture_print_stats() function in locktorture.c carefully
initializes local variable "min" to statp[0].n_lock_acquired, but
then compares it to statp[i].n_lock_fail. Given that the .n_lock_fail
field should normally be zero, and given the initialization, it seems
reasonable to display the maximum and minimum number acquisitions
instead of miscomputing the maximum and minimum number of failures.
This commit therefore switches from failures to acquisitions.
And this turns out to be not only a day-zero bug, but entirely my
own fault. I hate it when that happens!

commit 3670664b5da555a2a481449b3baafff113b0ac35 upstream.
ev_byte_channel_send() assumes that its third argument is a 16 byte
array. Some places where it is called it may not be (or we can't
easily tell if it is). Newer compilers have started producing warnings
about this, so make sure we actually pass a 16 byte array.
There may be more elegant solutions to this, but the driver is quite
old and hasn't been updated in many years.
The warnings (from a powerpc allyesconfig build) are:

Fix a debug-only build error in ext2/xattr.c:
When building without extra debugging, (and with another patch that uses
no_printk() instead of <empty> for the ext2-xattr debug-print macros,
this build error happens:
../fs/ext2/xattr.c: In function ‘ext2_xattr_cache_insert’:

this function); did you mean ‘ext2_xattr_list’?
atomic_read(&ext2_xattr_cache->c_entry_count));
Fix the problem by removing cached entry count from the debug message
since otherwise we'd have to export the mbcache structure just for that.

[ Upstream commit 1493e0f944f3c319d11e067c185c904d01c17ae5 ]
We have to properly retry again by returning -EINVAL immediately in case
somebody else instantiated the table concurrently. We missed to add the
goto in this function only. The code now matches the other, similar
shadowing functions.
We are overwriting an existing region 2 table entry. All allocated pages
are added to the crst_list to be freed later, so they are not lost
forever. However, when unshadowing the region 2 table, we wouldn't trigger
unshadowing of the original shadowed region 3 table that we replaced. It
would get unshadowed when the original region 3 table is modified. As it's
not connected to the page table hierarchy anymore, it's not going to get
used anymore. However, for a limited time, this page table will stick
around, so it's in some sense a temporary memory leak.
Identified by manual code inspection. I don't think this classifies as
stable material.

[ Upstream commit af9c5d2e3b355854ff0e4acfbfbfadcd5198a349 ]
compiletime_assert() uses __LINE__ to create a unique function name. This
means that if you have more than one BUILD_BUG_ON() in the same source
line (which can happen if they appear e.g. in a macro), then the error
message from the compiler might output the wrong condition.
For this source file:
#include <linux/build_bug.h>
#define macro() \
BUILD_BUG_ON(1); \
BUILD_BUG_ON(0);
void foo()
{
macro();
}
gcc would output:
./include/linux/compiler.h:350:38: error: call to `__compiletime_assert_9' declared with attribute error: BUILD_BUG_ON failed: 0
_compiletime_assert(condition, msg, __compiletime_assert_, __LINE__)
However, it was not the BUILD_BUG_ON(0) that failed, so it should say 1
instead of 0. With this patch, we use __COUNTER__ instead of __LINE__, so
each BUILD_BUG_ON() gets a different function name and the correct
condition is printed:
./include/linux/compiler.h:350:38: error: call to `__compiletime_assert_0' declared with attribute error: BUILD_BUG_ON failed: 1
_compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__)

machine_device_initcall(maple, maple_cpc925_edac_setup);

machine_device_initcall expands to __define_machine_initcall, which in
turn has the macro machine_is used in it, which declares mach_##name
with an __attribute__((weak)). define_machine actually defines
mach_##name, which in this file happens before the declaration, hence
the warning.
To fix this, move define_machine after machine_device_initcall so that
the declaration occurs before the definition, which matches how
machine_device_initcall and define_machine work throughout
arch/powerpc.
While we're here, remove some spaces before tabs.

[ Upstream commit 8605cf0e852af3b2c771c18417499dc4ceed03d5 ]
When dreq is allocated by nfs_direct_req_alloc(), dreq->kref is
initialized to 2. Therefore we need to call nfs_direct_req_release()
twice to release the allocated dreq. Usually it is called in
nfs_file_direct_{read, write}() and nfs_direct_complete().
However, current code only calls nfs_direct_req_relese() once if
nfs_get_lock_context() fails in nfs_file_direct_{read, write}().
So, that case would result in memory leak.
Fix this by adding the missing call.

[ Upstream commit 6fe38aa8cac3a5db38154331742835a4d9740788 ]
Tegra PMC clocks clk_out_1, clk_out_2, and clk_out_3 supported parents
are osc, osc_div2, osc_div4 and extern clock.
Clock driver is using incorrect parents clk_m, clk_m_div2, clk_m_div4
for PMC clocks.
This patch fixes this.

[ Upstream commit b0ecf1c6c6e82da4847900fad0272abfd014666d ]
clk_hw_round_rate() may call round rate function of its parents. In case
of SAM9X60 two of USB parrents are PLLA and UPLL. These clocks are
controlled by clk-sam9x60-pll.c driver. The round rate function for this
driver is sam9x60_pll_round_rate() which call in turn
sam9x60_pll_get_best_div_mul(). In case the requested rate is not in the
proper range (rate < characteristics->output[0].min &&
rate > characteristics->output[0].max) the sam9x60_pll_round_rate() will
return a negative number to its caller (called by
clk_core_round_rate_nolock()). clk_hw_round_rate() will return zero in
case a negative number is returned by clk_core_round_rate_nolock(). With
this, the USB clock will continue its rate computation even caller of
clk_hw_round_rate() returned an error. With this, the USB clock on SAM9X60
may not chose the best parent. I detected this after a suspend/resume
cycle on SAM9X60.

commit 25faa4bd37c10f19e4b848b9032a17a3d44c6f09 upstream.
At the error path of the firmware loading error, the driver tries to
release the card object and set NULL to drvdata. This may be referred
badly at the possible PM action, as the driver itself is still bound
and the PM callbacks read the card object.
Instead, we continue the probing as if it were no option set. This is
often a better choice than the forced abort, too.
