Linux 4.8 no longer boots, as it runs out of descriptor space. Readding
the mapping allows reuse, and the next AllocatePool will likely not add
a new mapping.
Also fix some small issues found while debugging.
v2, updated:
efi_loader: Fix memory map size check to avoid out-of-bounds access
- (Hopefully) clarified commit message
efi_loader: Track size of pool allocations to allow freeing
- rebased on top of 'efi_loader: Fix crash on 32-bit systems'
- assert correct address in efi_free_pool
- use EFI_PAGE_MASK instead of 0xfff, EFI_PAGE_SHIFT likewise
Stefan Brüns (6):
efi_loader: Update description of internal efi_mem_carve_out
efi_loader: Fix memory map size check to avoid out-of-bounds access
efi_loader: Track size of pool allocations to allow freeing
efi_loader: Readd freed pages to memory pool
efi_loader: Keep memory mapping sorted when splitting an entry
efi_loader: Do not leak memory when unlinking a mapping
