| H A D | hw_irq.h | d9ada91a Thu Mar 01 18:33:52 CST 2012 Benjamin Herrenschmidt <benh@kernel.crashing.org> powerpc: Replace mfmsr instructions with load from PACA kernel_msr field
On 64-bit, the mfmsr instruction can be quite slow, slower
than loading a field from the cache-hot PACA, which happens
to already contain the value we want in most cases.
