[PATCH] Add a MTD driver for OpenPower PNOR flash

2015-05-03 Thread Cyril Bur
Hi, I'm resending the patch that Jeremy Kerr sent a while back. This patch implements a simple mtd device to allow access to the PNOR flash on OpenPower machines. The flash is accessed through firmware calls. The firmware calls are already merged in: commit ed59190e41b725e1cfd79541f5fc66c20adb06

[PATCH] perf_event: Don't allow vmalloc backed perf on powerpc

2015-05-03 Thread Michael Ellerman
On powerpc the perf event interrupt is not masked when interrupts are disabled, allowing it to function as an NMI. This causes problems if perf is using vmalloc. If we take a page fault on the vmalloc region the fault handler will fail the page fault because it detects we are coming in from an NMI
