CONFIG_PM is now set whenever we support either runtime PM in addition
to suspend and hibernate. This causes build errors when runtime PM is
enabled on a platform, but the CPU does not have the appropriate support
for suspend.
So, switch this code to use CONFIG_PM_SLEEP rather than CONFIG_PM to
allow runtime PM to be enabled without causing build errors.

The recent commit (10774912647781) wasn't entirely correct. While
it fixed some issues, it introduced others. So pull in the fixes
from the public cache flush functions, and document why we need to
call things directly ourselves.

If the period of a gptimer is fairly low, we might miss an interrupt
by acking it too late (we end up acking the new int as well).

We only want to clear the run bit for this one timer, not all status bits.
So don't read the whole reg and then write all the bits back out.

When suspending/resuming, the common task freezing code will run in
parallel and freeze processes on each core. This is because the code
uses the non-smp version of memory barriers (as well it should).
The Blackfin smp barrier logic at the moment contains the cache sync
logic, but the non-smp barriers do not. This is incorrect as Rafel
summarized:
> ...
> The existing memory barriers are SMP barriers too, but they are more
> than _just_ SMP barriers. At least that's how it is _supposed_ to be
> (eg. rmb() is supposed to be stronger than smp_rmb()).
> ...
> However, looking at the blackfin's definitions of SMP barriers I see
> that it uses extra stuff that should _also_ be used in the definitions
> of the mandatory barriers.

Commit 8a5ec0ba "Lockless (and preemptless) fastpaths for slub" makes use
of this_cpu_cmpxchg_double() which needs this_cpu_cmpxchg16b_emu() on
x86_64. Implementing cmpxchg16b emulation for UML would introduce too
much complexity. So just disable it.

Commit 1de1502c ("x86, um: now we can get rid of trivial uml headers")
removed accidentally bug.h which broke UML's call tracer and bug
handler.
Without asm-generic/bug.h UML uses BUG() from arch/x86/ which makes use
of ud2. UML cannot use ud2, it raises SIGILL in user mode. As UML has
a different stack for handling signals the call trace will be cut off.

The ATAG_BOARDINFO is intended to hand over the information
bd->bi_board_number from u-boot to the kernel.
This piece of information can be used to implement some kind of board
identification while booting the kernel. Therefore it is placed in .initdata
section and can be accessed via the new symbol board_number only while
initializing the kernel.

platform_get_irq returns -ENXIO on failure, so !int_irq was probably
always true. Better use (int)int_irq <= 0. Note that a return value of
zero is still handled as error even though this could mean irq0.
This is a followup to 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that
changed the return value of platform_get_irq from 0 to -ENXIO on error.

We can delete the code that checks to see if we're sending an ignored
signal to init because force_sig_info() already handles this case.
force_sig_info() will kill init even if the signal handler is SIG_DFL
and the scenario described in the comment where init might "generate
the same exception over and over again" cannot occur (force_sig_info()
clears SIGNAL_UNKILLABLE to ensure that init will die).
Also, the use of is_global_init() is not correct in the multhreaded
case, as Oleg Nesterov explains,
"is_global_init() is not right in theory, /sbin/init can be
multithreaded. And, this doesn't cover the sub-namespace
inits... I'd suggest to check SIGNAL_UNKILLABLE, but looking
closer I think you can simply remove this code."
It seems this code was copied from arch/powerpc in March 2007 in commit
623b0355d5b1 "[AVR32] Clean up exception handling code"
but the code was deleted from arch/powerpc in November 2009 in commit
a0592d42fe3e "powerpc: kill the obsolete code under is_global_init()"
So catch up with powerpc and delete the bogus code.

When writing out /sys/kernel/debug/at32ap_clk, clock list lock is being
held while clk_get() is called. clk_get() attempts to take the same

Xen save/restore is going to use hibernate device callbacks for
quiescing devices and putting them back to normal operations and it
would need to select CONFIG_HIBERNATION for this purpose. However,
that also would cause the hibernate interfaces for user space to be
enabled, which might confuse user space, because the Xen kernels
don't support hibernation. Moreover, it would be wasteful, as it
would make the Xen kernels include a substantial amount of code that
they would never use.
To address this issue introduce new power management Kconfig option
CONFIG_HIBERNATE_CALLBACKS, such that it will only select the code
that is necessary for the hibernate device callbacks to work and make
CONFIG_HIBERNATION select it. Then, Xen save/restore will be able to
select CONFIG_HIBERNATE_CALLBACKS without dragging the entire
hibernate code along with it.

Xen fails to mask XSAVE from the cpuid feature, despite not historically
supporting guest use of XSAVE. However, now that XSAVE support has been
added to Xen, we need to reliably detect its presence.
The most reliable way to do this is to look at the OSXSAVE feature in
cpuid which is set iff the OS (Xen, in this case), has set
CR4.OSXSAVE.

Some (old) versions of Xen just kill the domain if it tries to set any
unknown bits in CR4, so we can't reliably probe for OSXSAVE in
CR4.
Since Xen doesn't support XSAVE for guests at the moment, and no such
support is being worked on, there's no downside in just unconditionally
masking XSAVE support.

There are valid situations in which this error is not
a warning. Mainly when QEMU maps a guest memory and uses
the VM_IO flag to set the MFNs. For right now make the
WARN be WARN_ONCE. In the future we will:
1). Remove the VM_IO code handling..
2). .. which will also remove this debug facility.

The latest binutils won't accept the stfl instruction with march=g5
which is the correct behaviour. Unfortunately head.S is assembled
with -march=g5 even if the target cpu is z900 or later. To get
31-bit kernels compiled again the easiest fix is to use the .insn
notation for the stfl instruction in head.S.

After the execution has been switched to the destination CPU, the target
function is called with the wrong parameter. According to the C calling
convention on s390, the first parameter should be loaded into register 2.
Currently in smp_restart_cpu() it is stored in register 3. To fix this, we
load the parameter into the correct register 2.

If several boards are enabled in the kernel configuration,
fsi_init_pm_clock() functions from board-ap4evb.c
will run on any of them. Prevent this by calling these functions from the
.init_machine() callback instead of using device_initcall().

too.

context switches), FPU exceptions in user mode cause Oopses, BUGs,

Restore the initialization of mmu_cr4_features during boot, which was
removed without comment in checkin e5f15b45ddf3afa2bbbb10c7ea34fb32b6de0a0e
x86: Cleanup highmap after brk is concluded
thereby breaking resume from hibernate. This restores previous
functionality in approximately the same place, and corrects the
reading of %cr4 on pre-CPUID hardware (%cr4 exists if and only if
CPUID is supported.)
However, part of the problem is that the hibernate suspend/resume
sequence should manage the save/restore of %cr4 explicitly.

Commit d8fc3afc49 (x86, NUMA: Move *_numa_init() invocations
into initmem_init()) moved acpi_numa_init() call into NUMA
initmem_init() but forgot to update 32bit NUMA init breaking ACPI
NUMA configuration for 32bit.
acpi_numa_init() call was later moved again to srat_64.c. Match
it by adding the call to get_memcfg_from_srat() in srat_32.c.
