This selftest is designed to cover execute-only protections
on the Radix MMU but will also work with Hash.
The tests are based on those found in pkey_exec_test with modifications
to use the generic mprotect() instead of the pkey variants.

Add support for execute-only memory (XOM) for the Radix MMU by using an
execute-only mapping, as opposed to the RX mapping used by powerpc's
other MMUs.
The Hash MMU already supports XOM through the execute-only pkey,
which is a separate mechanism shared with x86. A PROT_EXEC-only mapping
will

--- Comment #3 from Andrew Donnellan (a...@linux.ibm.com) ---
Patch has been taken via Kees Cook's hardening tree:
We used to have a workaround[1] for a hang during migration that was
made ineffective when we converted the decrementer expiry to be
relative to guest timebase.
The point of the workaround was that in the absence of an explicit
decrementer expiry value provided by userspace during migration, KVM
There should be no reason to adjust old ktermios which is going to get
discarded anyway.

Why rename the .h file? It still handles the "balloon compaction"

We were not correctly copying PTE dirty bits to pages during
migrate_vma_setup() calls. This could potentially lead to data loss, so
add a test for this.

migrate_vma_setup() has a fast path in migrate_vma_collect_pmd() that
installs migration entries directly if it can lock the migrating page.
When removing a dirty pte the dirty bit is supposed to be carried over
to the underlying page to prevent it being lost.
Currently migrate_vma_*() can only
