Stop using the non-uapi <linux/err.h> header file. We only need it for MAX_ERRNO, and it's time we had somewhere to put the little assembler utility macros we've been putting off writing.

Fix pread/pwrite for LP64. Unlike on 32-bit systems where off_t is 32-bit, we don't want to throw away the top 32 bits of an LP64 system's 64-bit off_t. Change-Id: Ib2e0daeb4fc0b8ab3d1b983d0b371d8f81033b50 2013-11-06 13:10:37 -08:00
