The builtin .dtb.S intermediate file needs to be marked with .SECONDARY
so that it isn't automatically deleted (which causes it to be
regenerated on every build). Also add *.dtb.S to clean-files so it gets
cleaned up by make clean.
Similarly, if the specified builtin dtb isn't already in dtb-y (e.g.
imported into the tree and specified in CONFIG_METAG_BUILTIN_DTB_NAME)
it too will be treated as an intermediate and deleted automatically
(again causing it to be regenerated on every build), so add it to dtb-y
so it gets added to targets and the dtbs target.

Borislav Petkov reported a lockdep splat warning about kzalloc()
done in an IPI (hardirq) handler.
This is a real bug, do not call kzalloc() in a smp_call_function_single()

In a previous commit the en_core_tk_irqen flag has been added but we missed
the cpuidle_wrap_enter which was doing the job to measure the time for the
'omap3_enter_idle' function.
Actually, I don't see any reason to use this wrapper in the code. In the better
case, the time computation is not correctly done because of the different
operations done in omap3_enter_idle_bm which were not taken into account
before the en_core_tk_irqen flag was set.
As the time is reflected for the state overridden by the omap3_enter_idle_bm,
using the wrapper is pointless now, so removing it.

Commit 688036b538974de32ce55be8b0e013b003992abc removed the function
'shmobile_enter_wfi' but we forgot to remove the definition in the header file.
Note this function is just an alias to 'cpu_do_idle()' wrapped into a cpuidle
function callback prototype which already exists with the default WFI state
and the arm_simple_enter function.
Remove the function prototype.

After a server reboot, the reclaimer thread will recover all the existing
locks. For locks that are blocked, however, it will change the value
of block->b_status to nlm_lck_denied_grace_period in order to signal that
they need to wake up and resend the original blocking lock request.
Due to a bug, however, the block->b_status never gets reset after the
blocked locks have been woken up, and so the process goes into an
infinite loop of resends until the blocked lock is satisfied.

The current update of the rq's load can be erroneous when RT
tasks are involved.
The update of the load of a rq that becomes idle, is done only
if the avg_idle is less than sysctl_sched_migration_cost. If RT
tasks and short idle duration alternate, the runnable_avg will
not be updated correctly and the time will be accounted as idle
time when a CFS task wakes up.
A new idle_enter function is called when the next task is the
idle function so the elapsed time will be accounted as run time
in the load of the rq, whatever the average idle time is. The
function update_rq_runnable_avg is removed from idle_balance.
When a RT task is scheduled on an idle CPU, the update of the
rq's load is not done when the rq exit idle state because CFS's
functions are not called. Then, the idle_balance, which is
called just before entering the idle function, updates the rq's
load and makes the assumption that the elapsed time since the
last update, was only running time.
As a consequence, the rq's load of a CPU that only runs a
periodic RT task, is close to LOAD_AVG_MAX whatever the running
duration of the RT task is.
A new idle_exit function is called when the prev task is the
idle function so the elapsed time will be accounted as idle time
in the rq's load.

check_hw_exists() has a number of checks which go to two exit
paths: msr_fail and bios_fail. Checks classified as msr_fail
will cause check_hw_exists() to return false, causing the PMU
not to be used; bios_fail checks will only cause a warning to be
printed, but will return true.
The problem is that if there are both msr failures and bios
failures, and the routine hits a bios_fail check first, it will
exit early and return true, not finishing the rest of the msr
checks. If those msrs are in fact broken, it will cause them to
be used erroneously.
In the case of a Xen PV VM, the guest OS has read access to all
the MSRs, but write access is white-listed to supported
features. Writes to unsupported MSRs have no effect. The PMU
MSRs are not (typically) supported, because they are expensive
to save and restore on a VM context switch. One of the
"msr_fail" checks is supposed to detect this circumstance (ether
for Xen or KVM) and disable the harware PMU.
However, on one of my AMD boxen, there is (apparently) a broken
BIOS which triggers one of the bios_fail checks. In particular,
MSR_K7_EVNTSEL0 has the ARCH_PERFMON_EVENTSEL_ENABLE bit set.
The guest kernel detects this because it has read access to all
MSRs, and causes it to skip the rest of the checks and try to
use the non-existent hardware PMU. This minimally causes a lot
of useless instruction emulation and Xen console spam; it may
cause other issues with the watchdog as well.
This changset causes check_hw_exists() to go through all of the
msr checks, failing and returning false if any of them fail.
This makes sure that a guest running under Xen without a virtual
PMU will detect that there is no functioning PMU and not attempt
to use it.
This problem affects kernels as far back as 3.2, and should thus
be considered for backport.

"The kexec/kdump people have found several problems with the support
for loading over 4 GiB that was introduced in this merge cycle. This
is partly due to a number of design problems inherent in the way the
various pieces of kdump fit together (it is pretty horrifically manual
in many places.)
After a *lot* of iterations this is the patchset that was agreed upon,
but of course it is now very late in the cycle. However, because it
changes both the syntax and semantics of the crashkernel option, it
would be desirable to avoid a stable release with the broken

Quartulli.
7) Revert build_skb() change sin IGB driver, can result in memory
corruption. From Alexander Duyck.
8) Fix setting VLANs on virtual functions in IXGBE, from Greg Rose.
9) Fix TSO races in qlcnic driver, from Sritej Velaga.
10) In bnx2x the kernel driver and UNDI firmware can try to program the
chip at the same time, resulting in corruption. Add proper
synchronization. From Dmitry Kravkov.
11) Fix corruption of status block in firmware ram in bxn2x, from Ariel
Elior.
12) Fix load balancing hash regression of bonding driver in forwarding
configurations, from Eric Dumazet.
13) Fix TS ECR regression in TCP by calling tcp_replace_ts_recent() in
all the right spots, from Eric Dumazet.
14) Fix several bonding bugs having to do with address manintainence,
including not removing address when configuration operations
encounter errors, missed locking on the address lists, missing
refcounting on VLAN objects, etc. All from Nikolay Aleksandrov.
15) Add workarounds for firmware bugs in LTE qmi_wwan devices, wherein
the devices fail to add a proper ethernet header while on LTE
networks but otherwise properly do so on 2G and 3G ones. From Bjørn
Mork.

Commit 257b5358b32f ("scm: Capture the full credentials of the scm
sender") changed the credentials passing code to pass in the effective
uid/gid instead of the real uid/gid.
Obviously this doesn't matter most of the time (since normally they are
the same), but it results in differences for suid binaries when the wrong
uid/gid ends up being used.
This just undoes that (presumably unintentional) part of the commit.

Somehow tracepoint_entry_add_probe() function allows a null probe function.
And, this may lead to unexpected results since the number of probe
functions in an entry can be counted by checking whether a probe is null
or not in the for-loop.
This patch prevents a null probe from being added.
In tracepoint_entry_remove_probe() function, checking probe parameter
within the for-loop is moved out for code efficiency, leaving the null probe
feature which removes all probe functions in the entry.

For each CPU vendor that implements CPU microcode patching, there will
be a minimum family for which this is implemented. Verify this
minimum level of support.
This can be done in the dispatch function or early in the application
functions. Doing the latter turned out to be somewhat awkward because
of the ineviable split between the BSP and the AP paths, and rather
than pushing deep into the application functions, do this in
the dispatch function.

If one does do something unfortunate and allow a
bad offload bug into the kernel, this the
skb_warn_bad_offload can effectively live-lock the
system, filling the logs with the same error over
and over.
Add rate limitation to this so that box remains otherwise
functional in this case.

When building ax88796 on an ARM platform with 64-bit resource_size_t,
we currently get
drivers/net/ethernet/8390/ax88796.c:875: undefined reference to `__aeabi_uldivmod'
because we do a division on the length of the MMIO resource.
Since we know that this resource is very short, using an
"unsigned long" instead of "resource_size_t" is entirely
sufficient, and avoids this link-time error.
