Commit df9ee292 ("Fix IRQ flag handling naming") changed the IRQ flag
handling naming scheme and broke UML:

The linker script cleanup that I did in commit 5d150a97f93 ("um: Clean up
linker script using standard macros.") (2.6.32) accidentally introduced an
ALIGN(PAGE_SIZE) when converting to use INIT_TEXT_SECTION; Richard
Weinberger reported that this causes the kernel to segfault with
CONFIG_STATIC_LINK=y.
I'm not certain why this extra alignment is a problem, but it seems likely
it is because previously
__init_begin = _stext = _text = _sinittext
and with the extra ALIGN(PAGE_SIZE), _sinittext becomes different from the
rest. So there is likely a bug here where something is assuming that
_sinittext is the same as one of those other symbols. But reverting the
accidental change fixes the regression, so it seems worth committing that
now.

This fixes a issue which was introduced by fe2cc53e ("uml: track and make
up lost ticks").
timeval_to_ns() returns long long and not int. Due to that UML's timer
did not work properlt and caused timer freezes.

For power management at91_pm_enter() routine, use the cpu_do_idle() for a
rock solid "wait for interrupt" implementation.
For AT91SAM9 ARM 926 based chips, we can exceed the cache line length as
we can access RAM even while in self-refresh mode.
We keep plain access to CP15 for at91rm9200 as this feature is not
available: instructions have to be in a single cache line.

Several at91sam9 chips need the alternate reset procedure to be sure to halt
SDRAM smoothly before resetting the chip.

affected.

Generalize assembler reset routine to allow use on several at91sam9 chips.
This patch replace double definitions of SDRAM controller registers and RSTC
registers with use of classical header files.
For this rework, we remove the not needed icache flush as it is already
done in the calling function: arm_machine_restart().
Rename at91sam9g20_reset.S to generalize to several chips.

In the MN10300 arch, we occasionally see an assertion being tripped in
alloc_cwqs() at the following line:
/* just in case, make sure it's actually aligned */
---> BUG_ON(!IS_ALIGNED(wq->cpu_wq.v, align));
return wq->cpu_wq.v ? 0 : -ENOMEM;
The values are:
wa->cpu_wq.v => 0x902776e0
align => 0x100
and align is calculated by the following:
const size_t align = max_t(size_t, 1 << WORK_STRUCT_FLAG_BITS,
__alignof__(unsigned long long));
This is because the pointer in question (wq->cpu_wq.v) loses some of its
lower bits to control flags, and so the object it points to must be
sufficiently aligned to avoid the need to use those bits for pointing to
things.
Currently, 4 control bits and 4 colour bits are used in normal
circumstances, plus a debugging bit if debugging is set. This requires
the cpu_workqueue_struct struct to be at least 256 bytes aligned (or 512
bytes aligned with debugging).
PERCPU() alignment on MN13000, however, is only 32 bytes as set in
vmlinux.lds.S. So we set this to PAGE_SIZE (4096) to match most other
arches and stick a comment in alloc_cwqs() for anyone else who triggers
the assertion.

Export the cpu configuration topology via sysinfo. Two new lines are
introduced:
CPU Topology HW: 0 0 0 4 6 4
CPU Topology SW: 0 0 0 0 4 24
The HW line describes the cpu topology nesting levels when the maximum
nesting level is used to get the corresponding SYSIB.
The SW line describes what Linux is actually using. In this case it
supports only two levels (CONFIG_SCHED_BOOK off) and therefore the
hardware folded the two lower levels in the SYSIB response block.

commit 050eef364ad700590a605a0749f825cab4834b1e
[S390] fix tlb flushing vs. concurrent /proc accesses
broke KVM on s390x. On every schedule a
Badness at include/asm/mmu_context.h:83 appears. s390_enable_sie
replaces the mm on the __running__ task, therefore, we have to
increase the attach count of the new mm.

Up to now print_cpu_info() uses the cpu address stored in it's local
lowcore to print a message to the console. The cpu address in the
lowcore is (in this case) however not the physical cpu address of the
local cpu. It's the address of the cpu that issued the sigp restart
which started the local cpu.
Fix this by using the store cpu address instruction instead.
It's not that anybody really cares since this is broken since more than
ten years...

The ieee_instruction_pointer can not be read from user space anymore
since git commit 613e1def6b52c399a8b72a5e11bc2e57d2546fb8, the ptrace
interface always returns zero. Remove it from the thread_struct. It
is still present in the user_regs_struct for compatability reasons.

All architectures besides s390 have pte_mkhuge() defined in pgtable.h.
