The on-chip northbridge's temperature sensor of the upcoming
AMD Trinity CPUs works the same as for the previous CPUs.
Since it has a different PCI-ID, we just add the new one to the list
supported by k10temp.
This allows to use the k10temp driver on those CPUs.

As long as there is no other non-const variable marked __initdata in the
same compilation unit it doesn't hurt. If there were one however
compilation would fail with
error: $variablename causes a section type conflict
because a section containing const variables is marked read only and so
cannot contain non-const variables.

Similar to a30dcb4f which fixed asus_atk0110.ko, I recently received a
bug report from someone hitting the same issue in acpi_power_meter.

Some configurations produce the following compile warning:
drivers/hwmon/adm1031.c: In function 'set_fan_auto_channel':
drivers/hwmon/adm1031.c:292: warning: 'reg' may be used uninitialized in this function
While this is a false positive, it can easily be fixed by overloading the return
value from get_fan_auto_nearest with both register value and error return code
(the register value is never negative). Coincidentially, that also reduces
module size by a few bytes.

In some configurations, BUG() does not result in an endless loop but returns to
the caller. This results in the following compiler warning:
drivers/hwmon/f75375s.c: In function 'duty_mode_enabled':

drivers/hwmon/f75375s.c: In function 'auto_mode_enabled':
drivers/hwmon/f75375s.c:295: warning: control reaches end of non-void function
Fix the warning by returning something sensible after BUG().

Split __lookup_hash into two component functions:
lookup_dcache - tries cached lookup, returns whether real lookup is needed
lookup_real - calls i_op->lookup

Everything arriving into if (!dentry) will have need_reval = 1.
Indeed, the only way to get there with need_reval reset to 0 would
be via
if (unlikely(d_need_lookup(dentry)))
goto unlazy;
if (unlikely(dentry->d_flags & DCACHE_OP_REVALIDATE)) {
status = d_revalidate(dentry, nd);
if (unlikely(status <= 0)) {
if (status != -ECHILD)
need_reval = 0;
goto unlazy;
...
unlazy:
/* no assignments to dentry */
if (dentry && unlikely(d_need_lookup(dentry))) {
dput(dentry);
dentry = NULL;
}
and if d_need_lookup() had already been false the first time around, it
will remain false on the second call as well.

d_lookup() *will* fail after successful d_invalidate(), if we are
holding i_mutex all along. IOW, we don't need to jump back to
l: - we know what path will be taken there and can do that (i.e.
d_alloc_and_lookup()) directly.

Since 3.2.12 and 3.3, some systems are failing to boot with a BUG_ON.
Some other systems using the pata_jmicron driver fail to boot because no
disks are detected. Passing pcie_aspm=force on the kernel command line
works around it.
The cause: commit 4949be16822e ("PCI: ignore pre-1.1 ASPM quirking when
ASPM is disabled") changed the behaviour of pcie_aspm_sanity_check() to
always return 0 if aspm is disabled, in order to avoid cases where we
changed ASPM state on pre-PCIe 1.1 devices.
This skipped the secondary function of pcie_aspm_sanity_check which was
to avoid us enabling ASPM on devices that had non-PCIe children, causing
trouble later on. Move the aspm_disabled check so we continue to honour
that scenario.

Now that all the slow-path code is gone from these functions, we can
inline them into the main caller - avc_has_perm_flags().
Now the compiler can see that 'avc' is allocated on the stack for this
case, which helps register pressure a bit. It also actually shrinks the
total stack frame, because the stack frame that avc_has_perm_flags()
always needed (for that 'avc' allocation) is now sufficient for the
inlined functions too.
Inlining isn't bad - but mindless inlining of cold code (see the
previous commit) is.

The selinux AVC paths remain some of the hottest (and deepest) codepaths
at filename lookup time, and we make it worse by having the slow path
cases take up I$ and stack space even when they don't trigger. Gcc
tends to always want to inline functions that are just called once -
never mind that this might make for slower and worse code in the caller.
So this tries to improve on it a bit by making the slow-path cases
explicitly separate functions that are marked noinline, causing gcc to
at least no longer allocate stack space for them unless they are
actually called. It also seems to help register allocation a tiny bit,
since gcc now doesn't take the slow case code into account.
Uninlining the slow path may also allow us to inline the remaining hot
path into the one caller that actually matters: avc_has_perm_flags().
I'll have to look at that separately, but both avc_audit() and
avc_has_perm_noaudit() are now small and lean enough that inlining them
may make sense.

The function for_each_cpu_mask() expects a *pointer* to struct
cpumask as its second argument, whereas select_fallback_rq()
passes the value itself.
And moreover, for_each_cpu_mask() has been marked as obselete
in include/linux/cpumask.h. So move to the more appropriate
for_each_cpu() variant.

Install commands should not be used to specify soft dependencies among
modules. When loading modules it's much better to have a softdep that
modprobe knows what's being done than having to fork/exec another
instance of modprobe to load the other module.
By using a softdep user has also an option to remove the dependencies
when removing the module (and if its refcount dropped to 0)
