Vitaly Kuzmichev	1a27f7d9c2	ARM: Align stack to 8 bytes ... The ARM ABI requires that the stack be aligned to 8 bytes as it is noted in Procedure Call Standard for the ARM Architecture: http://infocenter.arm.com/help/topic/com.arm.doc.ihi0042d/index.html Unaligned SP also causes the problem with variable-length arrays allocation when VLA address becomes less than stack pointer during aligning of this address, so the next 'push' in the stack overwrites first 4 bytes of VLA.

George G. Davis	409a07c9d7	ARM1136: Fix cache_flush() error and correct cpu_init_crit() comments ... The ARM1136 cache_flush() function uses the "mcr p15, 0, rn, c7, c7, 0" instruction which means "Invalidate Both Caches" when in fact the intent is to clean and invalidate all caches. So add an "mcr p15, 0, %0, c7, c10, 0" instruction to "Clean Entire Data Cache" prior to the "Invalidate Both Caches" instruction to insure that memory is consistent with any dirty cache lines. Also fix a couple of "flush v*" comments in ARM1136 cpu_init_crit() so that they correctly describe the actual ARM1136 CP15 C7 Cache Operations used. Signed-off-by: George G.
