Subject: [PATCH] grub-mkconfig.in: turn off executable owner bit
Stricker permissions are required on the grub.cfg file, resulting in
at most 0600 owner's file permissions. This resolves conflicting
requirement permissions on grub2-pc package's grub2.cfg file.
Resolves: RHEL-45870

Subject: [PATCH] grub2-mkconfig: Ensure grub cfg stub is not overwritten
/boot/efi/EFI/$os_name/grub.cfg contains a grub cfg stub
that should not be overwritten by grub2-mkconfig.
Ensure that we prevent this from happening.

Subject: [PATCH] grub/mkconfig: Remove check for mount point for grub cfg stub
Remove mountpoint when checking whether or not the grub cfg stub
exists and add -s to the test. This should cover scenarios where
the ESP doesn't have a seperate partition but still uses a grub
cfg stub

Subject: [PATCH] arm64: Use proper memory type for kernel allocation
Currently, the kernel pages are allocated with type EFI_LOADER_DATA.
While the vast majority of systems will happily execute code from those
pages (i.e. don't care about memory protection), the Microsoft Surface
Pro X stalls, as this memory is not designated as "executable".
Therefore, allocate the kernel pages as EFI_LOADER_CODE to request
memory that is actually executable.
