Using of PAT to change pages from WB to WC works quite nicely.
Changing it back to WB - not so much. The crux of the matter is
that the code that does this (__page_change_att_set_clr) has only
limited information so when it tries to the change it gets
the "raw" unfiltered information instead of the properly filtered one -
and the "raw" one tell it that PSE bit is on (while infact it
is not).  As a result when the PTE is set to be WB from WC, we get
tons of:

for every page. The proper fix for this is has been posted
and is https://lkml.org/lkml/2012/2/10/228
"x86/cpa: Use pte_attrs instead of pte_flags on CPA/set_p.._wb/wc operations."
along with a detailed description of the problem and solution.

But since that posting has gone nowhere I am proposing
this band-aid solution so that at least users don't get
the page corruption (the pages that are WC don't get changed to WB
and end up being recycled for filesystem or other things causing
mysterious crashes).

The negative impact of this patch is that users of WC flag
(which are InfiniBand, radeon, nouveau drivers) won't be able
to set that flag - so they are going to see performance degradation.
But stability is more important here.

       \- play_dead [assuming the user offlined the VCPU]

       +- preempt_enable_no_reschedule()
       +- schedule()

So we have two preempt_disble() and one preempt_enable(). Calling
preempt_enable() after the cpu_bringup() in the xen_play_dead
fixes the imbalance.

When the initial domain starts, it prints (depending on the
amount of CPUs) a slew of
XENBUS: Unable to read cpu state
XENBUS: Unable to read cpu state
XENBUS: Unable to read cpu state
XENBUS: Unable to read cpu state

which provide no useful information - as the error is a valid
issue - but not on the initial domain. The reason is that the
XenStore is not accessible at that time (it is after all the
first guest) so the CPU hotplug watch cannot parse "availability/cpu"
attribute.

If NR_CPUS < 256 then arch_spinlock_t is only 16 bits wide but struct
xen_spinlock is 32 bits.  When a spin lock is contended and
xl->spinners is modified the two bytes immediately after the spin lock
would be corrupted.

This is a regression caused by 84eb950d
(x86, ticketlock: Clean up types and accessors) which reduced the size
of arch_spinlock_t.

Fix this by making xl->spinners a u8 if NR_CPUS < 256.  A
BUILD_BUG_ON() is also added to check the sizes of the two structures
are compatible.

In many cases this was not noticable as there would often be padding
bytes after the lock (e.g., if any of CONFIG_GENERIC_LOCKBREAK,
CONFIG_DEBUG_SPINLOCK, or CONFIG_DEBUG_LOCK_ALLOC were enabled).

The bnx2 driver is affected. In struct bnx2, phy_lock and
indirect_lock may have no padding after them.  Contention on phy_lock
would corrupt indirect_lock making it appear locked and the driver
would deadlock.

This patch fixes an (ACPI S3) suspend regression introduced in commit
68d6e671 ("tpm: Introduce function to poll for result of self test")
and occurring with an Infineon TPM and tpm_tis and tpm_infineon drivers
active.

The suspend problem occurred if the TPM was disabled and/or deactivated
and therefore the TPM_PCRRead checking the result of the (asynchronous)
self test returned an error code which then caused the tpm_tis driver to
become inactive and this then seemed to have negatively influenced the
suspend support by the tpm_infineon driver...  Besides that the tpm_tis
drive may stay active even if the TPM is disabled and/or deactivated.

ACPI 5.0 provides extensions to the EINJ mechanism to specify the
target for the error injection - by APICID for cpu related errors,
by address for memory related errors, and by segment/bus/device/function
for PCIe related errors. Also extensions for vendor specific error
injections.
