grub-core/kern/arm/misc.S: fix unaligned grub_uint64_t local variable
...
The unaligned local in __aeabi_uidivmod leads to a store to a 64bit
value at an address that is not divisible by 8 (in grub_divmod64).
The compiler most likely generates a STRD instruction to store it and
this causes an exception.
Fixes Savannah bug #43632 .
This includes improvements done by Leif Lindholm.

* grub-core/kern/arm/cache_armv6.S: Remove .arch directive.
...
As these functions are used on pre-ARMv6 CPUs as well we don't want
to make assembler assume that architecture is higher than default one.

arm: fix u-boot port syscall interface va_arg handling
...
Commit c9cd02c
broke the u-boot syscall API for va_args that spill over
to the stack, causing the disk support to stop working. This patch
resolves the problem, while keeping the new, cleaner transition_space
handling.
