Subject: [PATCH 056/194] efi: refactor grub_efi_allocate_pages
|
|
|
|
Expose a new function, grub_efi_allocate_pages_real(), making it possible
|
|
to specify allocation type and memory type as supported by the UEFI
|
|
AllocatePages boot service.
|
|
|
|
Make grub_efi_allocate_pages() a consumer of the new function,
|
|
maintaining its old functionality.
|
|
|
|
Also delete some left-around #if 1/#else blocks in the affected
|
|
functions.
|
