This configuration variable will be used to build the code needed to
handle speculative page fault.
By default it is turned off, and activated depending on architecture
support, SMP and MMU.

We need to relocate selinux_state to a separate 4k page
to enable EL2 Hypervisor to monitor changes to this
variable using ARM stage 2 MMU. We will avoid getting
page faults from un-related data as the MMU granularity
is configured to 4k.

Check whether size of fd is greater than or equal to

Two new fields in the struct vm_fault can't easily be excluded using
CONFIG_SPECULATIVE_PAGE_FAULTS. Add them as padding to reduce the
ABI diff between vendors which use SPECULATIVE_PAGE_FAULTS and ACK. This
allows vendors to pick the SPECULATIVE_PAGE_FAULTS feature and still be
ABI compatible with ACK.

The allocation code hot-adds the memory from another VM through
the memory hotplug code to create the S1 CPU MMU mappings. The memory
hotplug code can only add memory at a subsection granule, meaning
that all memory requests must be subsection size aligned. Thus,
enforce all allocation requests to be subsection size aligned.

Client drivers may lend IRQs with knowledge of only their GPIO interrupt
number, which would not directly have an underlying GIC hwirq. Thus,
tweak RM's understanding of IRQs to be aware of IRQ domains. Now, the
irq backed by GPIO will be translated to GIC domain.

If a biased cpu entered shallowest LPM state and
there are no wakeups for it, can stay in the shallowest
state for long.
Program wakeup for the biased CPU to wakeup after the
expected bias window is completed, so that the cpu can
enter a deeper state.
