8c534b85f1 Revamp relocation handling.
Move more code to common dl.c. Add missing veneers for arm and arm64.
	Decreases kernel size by 70 bytes on i386-pc (40-50 compressed)

e5ed2f6947 Handle unaligned .bss on sparc64.
Current code improperly assumes that both __bss_start and _end are
	aligned to 8-bytes. Eliminating this assumption and explicitly align
	modules.

2d76b4d81e Eliminate variable length arrays in grub_vsnprintf_real.
A bit tricky because this function has to continue to work without
	heap for short strings. Fixing prealloc to 32 arguments is reasonable
	but make all stack references use 32-bit offset rather than 8-bit one.
	So split va_args preparsing to separate function and put the prealloc
	into the caller.

4e42521d8c * grub-core/kern/x86_64/efi/callwrap.S: Fix stack alignment.
Previously we misaligned stack by 8 in startup.S and compensated
	for it in callwrap.S. According to ABI docs (EFI and sysv amd64)
	right behaviour is to align stack in startup.S and keep it aligned
	in callwrap.S. startup.S part was committed few commits before. This
	takes care of callwrap.S.

7960d3e182 * grub-core/kern/x86_64/efi/startup.S (_start): Align the stack to a
16-byte boundary, as required by the x86-64 ABI, before calling
	grub_main.  In some cases, GCC emits code that assumes this
	alignment, which crashes if not aligned.  The EFI firmware is also
	entitled to assume that stack alignment without checking.

593865b907 arm: fix u-boot port syscall interface va_arg handling
Commit c9cd02c broke the u-boot syscall API for va_args that spill over

resolves the problem, while keeping the new, cleaner transition_space
handling.
