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.

There is a bug in commit 6dda9d55 ("page allocator: reduce fragmentation in buddy allocator by adding buddies that are merging to the tail of the free lists") that means a buddy at order MAX_ORDER is checked for merging. A page of this order never exists so at times, an effectively random piece of memory is being checked. Alan Curry has reported that this is causing memory corruption in userspace data on a PPC32 platform (http://lkml.org/lkml/2010/10/9/32). It is not clear why this is happening. It could be a cache coherency problem where pages mapped in both user and kernel space are getting different cache lines due to the bad read from kernel space (http://lkml.org/lkml/2010/10/13/179). It could also be that there are some special registers being io-remapped at the end of the memmap array and that a read has special meaning on them. Compiler bugs have been ruled out because the assembly before and after the patch looks relatively harmless. This patch fixes the problem by ensuring we are not reading a possibly invalid location of memory. It's not clear why the read causes corruption but one way or the other it is a buggy read.

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. Signed-off-by: NNicolas Ferre <nicolas.ferre@atmel.com>

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.

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.
