Merge branch 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM fixes from Russell King:
"Three fixes this time around:
- fix a memory leak which occurs when probing performance monitoring
unit interrupts
- fix handling of non-PMD aligned end of RAM causing boot failures
- fix missing syscall trace exit path with syscall tracing enabled
causing a kernel oops in the audit code"
* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
ARM: 8357/1: perf: fix memory leak when probing PMU PPIs
ARM: fix missing syscall trace exit
ARM: 8356/1: mm: handle non-pmd-aligned end of RAM
