Subject: [PATCH] Make debug=file show which file filters get run.
If one of the file filters breaks things, it's hard to figure out where
it has happened.
This makes grub log which filter is being run, which makes it easier to
figure out where you are in the sequence of events.

Subject: [PATCH] efi: use enumerated array positions for our allocation
choices
In our kernel allocator on EFI systems, we currently have a growing
amount of code that references the various allocation policies by
position in the array, and of course maintenance of this code scales
very poorly.
This patch changes them to be enumerated, so they're easier to refer to
farther along in the code without confusion.

Subject: [PATCH] efi: split allocation policy for kernel vs initrd memories.
Currently in our kernel allocator, we use the same set of choices for
all of our various kernel and initramfs allocations, though they do not
have exactly the same constraints.
This patch adds the concept of an allocation purpose, which currently
can be KERNEL_MEM or INITRD_MEM, and updates kernel_alloc() calls
appropriately, but does not change any current policy decision. It
also adds a few debug prints.

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

Subject: [PATCH] ieee1275: implement vec5 for cas negotiation
As a legacy support, if the vector 5 is not implemented, Power
Hypervisor will consider the max CPUs as 64 instead 256 currently
supported during client-architecture-support negotiation.
This patch implements the vector 5 and set the MAX CPUs to 256 while
setting the others values to 0 (default).
