Atish Patra	950accbabd	efi/libstub: Fix gcc error around __umoddi3 for 32 bit builds ... 32bit gcc doesn't support modulo operation on 64 bit data. It results in a __umoddi3 error while building EFI for 32 bit. Use bitwise operations instead of modulo operations to fix the issue.

Ard Biesheuvel	43b1df0e01	efi/libstub: Add API function to allocate aligned memory ... Break out the code to create an aligned page allocation from mem.c and move it into a function efi_allocate_pages_aligned() in alignedmem.c. Update efi_allocate_pages() to invoke it unless the minimum alignment equals the EFI page size (4 KB), in which case the ordinary page allocator is sufficient. This way, efi_allocate_pages_aligned() will only be pulled into the build if it is actually being used (which will be on arm64 only in the immediate future) Signed-off-by: Ard Biesheuvel <ardb@kernel.org>	2020-04-24 14:52:16 +02:00
