Subject: [PATCH 061/229] efi: change heap allocation type to
|
2017-08-16 15:14:30 +00:00
|
|
|
GRUB_EFI_LOADER_CODE
|
|
|
|
|
|
|
|
With upcoming changes to EDK2, allocations of type EFI_LOADER_DATA may
|
|
|
|
not return regions with execute ability. Since modules are loaded onto
|
|
|
|
the heap, change the heap allocation type to GRUB_EFI_LOADER_CODE in
|
|
|
|
order to permit execution on systems with this feature enabled.
|
|
|
|
|
|
|
|
Closes: 50420
