On MMUs such as FSL where we can guarantee the entire linear mapping is
bolted, we don't need to worry about linear TLB misses. If on top of
that we do a full table walk, we get rid of all recursive TLB faults, and
can dispense with some state saving. This gains a few percent on
TLB-miss-heavy wo
The audit system previously expected arches calling to audit_syscall_exit to
supply as arguments if the syscall was a success and what the return code was.
Audit also provides a helper AUDITSC_RESULT which was supposed to simplify
things
by converting from negative retcodes to an audit internal ma

The Freescale hypervisor management driver provides several services to
drivers and applications related to the Freescale hypervisor:
1. An ioctl interface for querying and managing partitions
2. A file interface to reading incoming doorbells
3. An interrupt handler for shutting down the partiti
Facilitate the use of CONFIG_SECCOMP_FILTER by wrapping compatibility
system call numbering for execve and selecting HAVE_SECCOMP_FILTER.

Backport upstream commit 6de06f313a65d0ec
Commit fa3f82c8bb7acb ("powerpc/smp: soft-replugged CPUs must go back to
start_secondary") introduced start_secondary_resume to head_32.S, however
it uses a 64-bit instruction which is not valid on 32-bit platforms. Use
'stw' instead.
