The IO accessors for U300 were using u32 rather than the nominal
void __iomem * type, rectify this by properly defining the
virtual base for statically mapped peripherals to be
void __iomem *. Requires fixing a field in struct clk as well.

This reverts commit 45b95235b0.
Will Deacon reports that:
In 52af9c6c ("ARM: 6943/1: mm: use TTBR1 instead of reserved context ID")
I updated the ASID rollover code to use only the kernel page tables
whilst updating the ASID.
Unfortunately, the code to restore the user page tables was part of a
later patch which isn't yet in mainline, so this leaves the code
quite broken.
We're also in the process of eliminating __ARCH_WANT_INTERRUPTS_ON_CTXSW
from ARM, so lets revert these until we can properly sort out what we're
doing with the context switching.

This patch fixes the lockdep warning of "unannotated irqs-off"[1].
After entering __irq_usr, arm core will disable interrupt automatically,
but __irq_usr does not annotate the irq disable, so lockdep may complain
the warning if it has chance to check this in irq handler.
This patch adds trace_hardirqs_off in __irq_usr before entering irq_handler
to handle the irq, also calls ret_to_user_from_irq to avoid calling
disable_irq again.
This is also a fix for irq off tracer.

Quite a few functions that get called from the tlb gather code require that
preemption must be disabled. So disable preemption inside of the called
functions instead.
The only drawback is that rcu_table_freelist_finish() doesn't get necessarily
called on the cpu(s) that filled the free lists. So we may see a delay, until
we finally see an rcu callback. However over time this shouldn't matter.
So we get rid of lots of "BUG: using smp_processor_id() in preemptible"

"[S390] merge page_test_dirty and page_clear_dirty".
Result is that we read/write storage keys from random pages and do not

E.g. SetPageUpdate() doesn't clear the dirty bit of requested pages, which
for example ext4 doesn't like very much and panics after a while.

mwait_idle() is a C1-only idle loop intended to be more efficient
than HLT on SMP hardware that supports it.
But mwait_idle() has been replaced by the more general
mwait_idle_with_hints(), which handles both C1 and deeper C-states.
ACPI uses only mwait_idle_with_hints(), and never uses mwait_idle().
Deprecate mwait_idle() and the "idle=mwait" cmdline param
to simplify the x86 idle code.
After this change, kernels configured with
(!CONFIG_ACPI=n && !CONFIG_INTEL_IDLE=n) when run on hardware
that support MWAIT will simply use HLT. If MWAIT is desired
on those systems, cpuidle and the cpuidle drivers above
can be used.

We'd rather that modern machines not check if HLT works on
every entry into idle, for the benefit of machines that had
marginal electricals 15-years ago. If those machines are still running
the upstream kernel, they can use "idle=poll". The only difference
will be that they'll now invoke HLT in machine_hlt().

CONFIG_APM_CPU_IDLE is of dubious value, it runs only on 32-bit
uniprocessor laptops that are over 10 years old. It calls into
the BIOS during idle, and is known to cause a number of machines

Removing CONFIG_APM_CPU_IDLE and will allow us to stop exporting

This code was mostly developed against a BF54x, so some BF537-specific
issues were missed.
The PPI block starts at PPI_CONTROL, not PPI_STATUS (which is the reverse
of the EPPI block).
The MDMA block starts at MDMA_NEXT_DESC_PTR, not MDMA_CONFIG. Seems the
sim does not catch misreads here so that'll need to get fixed.
The gptimer block is mostly 32bit regs, not 16bit. Use the gptimer struct

setns is an easy system call to wire up. It just takes two ints so I
don't expect any weird architecture porting problems.
While doing this I have noticed that we have some architectures that are
very slow to get new system calls. cris seems to be the slowest where
the last system calls wired up were preadv and pwritev. avr32 is weird
in that recvmmsg was wired up but never declared in unistd.h. frv is
behind with perf_event_open being the last syscall wired up. On h8300
the last system call wired up was epoll_wait. On m32r the last system
call wired up was fallocate. mn10300 has recvmmsg as the last system
call wired up. The rest seem to at least have syncfs wired up which was
new in the 2.6.39.

x86-64: Move vread_tsc into a new file with sensible options
Removed the -pg from tsc.o which caused the function graph tracer

internally outside its recursion protection, thus tracing the tsc
breaks the function graph tracer.
This commit also added the file vread_tsc_64.c that gets used
by vdso but failed to prevent GCOV from monkeying with it,
causing userspace to try to access kernel data when GCOV was
enabled.
Thanks to Thomas Gleixner for pointing out GCOV as the likely
culprit that added strange kernel accesses into the vread_tsc()
call.

The software division functions never had unwinding annotations
added. Currently, when a division by zero occurs the backtrace shown
will stop at Ldiv0 or some completely unrelated function. Add
unwinding annotations in hopes of getting a more useful backtrace
when a division by zero occurs.
