[ARM] 4074/1: Flat loader stack alignment The ARM EABI requires doubleword (8-byte) stack alignment at all public entry points. The patch below makes the bFLT loader honour this. It's always safe to start with a doubleword aligned stack so it doesn't seem worth making this conditional on CONFIG_AEABI.

/* An odd number of words will be pushed after this alignment, so
deliberately misalign the value. */

[ARM] nommu: fix breakage caused by f9720205d1f847cb59e197e851b5276425363f6b Someone forgot to use 'ls include/asm-*/flat.h' or 'grep -r flat_get_addr_from_rp .' to find all architectures which may be affected by their change.
