3.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Will Deacon <will.deacon@xxxxxxx> commit f2fe09b055e2549de41fb107b34c60bac4a1b0cf upstream. Masked out PMXEVTYPER.NSH means that we can't enable profiling at PL2, regardless of the settings in the HDCR. This patch fixes the broken mask.
