Will Deacon ec45d1cfd3 arm64: mm: update CONTEXTIDR register to contain PID of current process ... This patch is a port of 575320d62 ("ARM: 7445/1: mm: update CONTEXTIDR register to contain PID of current process") from ARM that introduces a new Kconfig option which, when enabled, causes the kernel to write the PID of the current task into the CONTEXTIDR register on context switch. This is useful when analysing hardware trace, since writes to this register can be configured to emit an event into the trace stream.
