Merge tag 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King:
- remove a misuse of kernel-doc comment
- use "Call trace:" for backtraces like other architectures
- implement copy_from_kernel_nofault_allowed() to fix a LKDTM test
- add a "cut here" line for prefetch aborts
- remove unnecessary Kconfing entry for FRAME_POINTER
- remove iwmmxy support for PJ4/PJ4B cores
- use bitfield helpers in ptrace to improve readabililty
- check if folio is reserved before flushing
