Subject: [PATCH] efi: use EFI_LOADER_(CODE|DATA) for kernel and initrd
|
|
|
fd0330 |
allocations
|
|
|
fd0330 |
|
|
|
fd0330 |
At some point due to an erroneous kernel warning, we switched kernel and
|
|
|
fd0330 |
initramfs to being loaded in EFI_RUNTIME_SERVICES_CODE and
|
|
|
fd0330 |
EFI_RUNTIME_SERVICES_DATA memory pools. This doesn't appear to be
|
|
|
fd0330 |
correct according to the spec, and that kernel warning has gone away.
|
|
|
fd0330 |
|
|
|
fd0330 |
This patch puts them back in EFI_LOADER_CODE and EFI_LOADER_DATA
|
|
|
fd0330 |
allocations, respectively.
