signals that the firmware PE/COFF loader supports splitting code and
data sections of PE/COFF images into separate EFI memory map entries.
This allows the kernel to map those regions with strict memory
protection
From: Matt Fleming
Folks,
The patches in this pull request fix kernel crashes when booting Linux
on UEFI v2.5 machines with the Properties Table feature enabled.
Essentially, when this feature is enabled the firmware allocates
separate entries in the EFI memory map for the code and data section

In case a vcpu off PSCI call is called just after we executed the
vcpu_sleep check, we can enter the guest although power_off
is set. Let's check the power_off state in the critical section,
just before entering the guest.

The kvm_vcpu_arch pause field is renamed into power_off to prepare

We introduce kvm_arm_halt_guest and resume functions. They

Halt is synchronous and prevents the guest from being re-entered.
We use the same mechanism put in place for PSCI former pause,
