Re: [PATCH] powerpc/crypto/crc32c-vpmsum: Fix missing preempt_disable()

Hi Michael, We'll also need a similar patch for the t10dif code that went in to Herbert's next. I will do a patch once I get my development environment up and going again. Regards, Daniel Michael Ellerman writes: > In crc32c_vpmsum() we call enable_kernel_altivec()
