Subject: [PATCH] powerpc/crc: include <linux/uaccess.h>

From: Eric Biggers <ebiggers@...gle.com>

Since <asm/simd.h> no longer transitively includes <linux/uaccess.h>
which provides pagefault_disable() and pagefault_enable(),
<linux/uaccess.h> now needs to be included directly.

Fixes: 7ba8df47810f ("asm-generic: Make simd.h more resilient")
Signed-off-by: Eric Biggers <ebiggers@...gle.com>

I can take this via the crc tree, but it really should go via crypto
since the patch that broke this is in there...
