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.
	Reported by: Gary Lin.

054efe541f * grub-core/boot/mips/startup_raw.S: Handle the case of gap between
.data and .bss. May happen if compiler and assembly use different
	alignment.

0d8f04cd83 Remove -march=mips3 from TARGET_CCASFLAGS as it creates linking problem
when rest of GRUB is compiled for hisher stepping. Instead use
	.set mips3/.set mips1 around cache and sync opcodes.

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.

d53f4900d7 * grub-core/mmap/efi/mmap.c (grub_mmap_register): Round up/down to

45bf8b3a75 * grub-core/kern/mm.c (grub_real_malloc): Decrease cut-off of moving the
pointer to 32K. This is the size of cache element which is the most
	common allocation >1K. This way the pointer is always around blocks
	of 32K and so we keep performance while decreasing fragmentation.

39ff43c579 * grub-core/kern/mm.c (grub_real_malloc): Don't update the pointer to

cd46aa6cef Rewrite grub-install, grub-mkrescue, grub-mkstandalone and grub-mknetdir
the function of these files exceeds what can be sanely handled in shell
	in posix-comaptible way. Also writing it in C extends the functionality
	to non-UNIX-like OS and minimal environments.

080603f0b0 Decrease stack usage in lexer.
We have only 92K of stack and using over 4K per frame is wasteful

	* grub-core/script/yylex.l (yyalloc), (yyfree), (yyrealloc): Declare
	as macros so that compiler would remove useless structure on stack.
	Better solution would be to fix flex not to put this structure on
	the stack but flex is external program.

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
to the stack, causing the disk support to stop working. This patch
resolves the problem, while keeping the new, cleaner transition_space
handling.

6fcec43954 Replace libgcc version of ctz with our own.
On upcoming arm64 port libgcc ctz* are not usable in standalone
