  selftests/rseq: Fix build with undefined __weak (2023-08-04 18:10:29 -0400)

I won't be around for the next couple weeks, so while submaintainers are
welcome to send me their merge window pull requests, any bug fixes will have
to go through the architecture trees.  At least for x86 things seem to be in
check, though.

Paolo

----------------------------------------------------------------
x86:

* Fix SEV race condition

ARM:

* Fixes for the configuration of SVE/SME traps when hVHE mode is in use

* Allow use of pKVM on systems with FF-A implementations that are v1.0
  compatible

* Request/release percpu IRQs (arch timer, vGIC maintenance) correctly
  when pKVM is in use

* Fix function prototype after __kvm_host_psci_cpu_entry() rename

* Skip to the next instruction when emulating writes to TCR_EL1 on
  AmpereOne systems

Selftests:

* Fix missing include
