The cpu idle field in the output of /proc/stat is too small for cpus
that have been idle for more than a tick. Add the architecture hook
arch_idle_time that allows to add the not accounted idle time of a
sleeping cpu without waking the cpu.
The s390 implementation of arch_idle_time uses the already existing
s390_idle_data per_cpu variable to find the sleep time of a neighboring
idle cpu.

The appldata_ops callbacks are called with a spin_lock held. But the
appldata_mem callback then calls all_vm_events(), which calls
get_online_cpus(), which might sleep. This possible deadlock is fixed
by using a mutex instead of a spin_lock.

Reorder locking as down_read() may return with local interrupts enabled,
which means we could go into vti_vcpu_run() with interrupts enabled.
This caused random crashes on the Altix as the timer interrupt tried
to read a memory mapped clock source, for which the TLB had not yet been
reinstated in the exit, before ipsr was retored.

If there is a dummy "espdma" or "ledma" parent device above ESP scsi
or LE ethernet device nodes, we have to match the bus as SBUS.
Otherwise the address and size cell counts are wrong and we don't
calculate the final physical device resource values correctly at all.
Commit 5280267c1dddb8d413595b87dc406624bb497946 ("sparc: Fix handling
of LANCE and ESP parent nodes in of_device.c") was meant to fix this
problem, but that only influences the inner loop of
build_device_resources(). We need this logic to also kick in at the
beginning of build_device_resources() as well, when we make the first
attempt to determine the device's immediate parent bus type for 'reg'
property element extraction.
Based almost entirely upon a patch by Friedrich Oslage.

Now that ppc32 implements address randomization it also wants to inherit
personality flags like ADDR_NO_RANDOMIZE across exec, for things like
`setarch ppc -R' to work. But the ppc32 version of SET_PERSONALITY
forcefully sets PER_LINUX, clearing all personality flags. So be
careful about preserving the flags.

In non-SMP mode, the variable section attribute specified by DECLARE_PER_CPU()
does not agree with that specified by DEFINE_PER_CPU(). This means that
architectures that have a small data section references relative to a base
register may throw up linkage errors due to too great a displacement between
where the base register points and the per-CPU variable.
On FRV, the .h declaration says that the variable is in the .sdata section, but
the .c definition says it's actually in the .data section. The linker throws
up the following errors:
kernel/built-in.o: In function `release_task':
kernel/exit.c:78: relocation truncated to fit: R_FRV_GPREL12 against symbol `per_cpu__process_counts' defined in .data section in kernel/built-in.o
kernel/exit.c:78: relocation truncated to fit: R_FRV_GPREL12 against symbol `per_cpu__process_counts' defined in .data section in kernel/built-in.o
To fix this, DECLARE_PER_CPU() should simply apply the same section attribute
as does DEFINE_PER_CPU(). However, this is made slightly more complex by
virtue of the fact that there are several variants on DEFINE, so these need to
be matched by variants on DECLARE.

Insert PCI root bus resources for the FRV-based MB93090 development kit
motherboard. This is required because the CPU's window onto the PCI bus
address space is considerably smaller than the CPU's full address space
and non-PCI devices lie outside of the PCI window that we might want to
access.
Without this patch, the PCI root bus uses the platform-level bus
resources, and these are then confined to the PCI window, thus making
platform_device_add() reject devices outside of this window.

The ULI 1575 PCI quirk function for the Freescale MPC8610 HPCD was disabling
the SATA INTx interrupt, even when SATA support was enabled. This was safe,
because the SATA driver re-enabled it. But with commit a5bfc471 ("ahci: drop
intx manipulation on msi enable"), the driver no longer does this, and so SATA
support on the 8610 HPCD is broken.
The original quirk function disabled INTx because it caused some other
interrupt problem during early development on this board, but no one remembers
any more what that problem was, and it doesn't seem to occur any more.

This patch fixes the following compilation error caused by recursive
inclusion of kernel.h which defines BUILD_BUG_ON().
In this case, the case it catches will be caught by the case
CONFIG_PARAVIRT=n, so removing it would not hurt compile time check
very much. So fix the breakage by removing it.

This renames include/asm-h8300/timer.h into arch/h8300/include/asm: it
was left over just because that file had been created in the -mm tree
before the whole h8300 header subdirectory had been moved, and then got
merged in the old location afterwards.
(See commits e0b0f9e4ead2468f84c26332ec42b118e76af572: "h8300: update
timer handler - new files" and 758db3f2118703a1e36374dae5d58bed963e7e0d:
"[h8300] move include/asm-h8300 to arch/h8300/include/asm" for details).
This also removes a left-over .gitignore file in include/asm-arm that
became stale when the ARM header files were moved (which happened in
multiple commits, just see "git log -- include/asm-arm" for details).
