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 <sys/resource.h>. The situation here is a bit confusing. On 64-bit, rlimit and rlimit64 are the same, and so getrlimit/getrlimit64, setrlimit/setrlimit64, and prlimit/prlimit64 are all the same. On 32-bit, rlimit and rlimit64 are different. 32-bit architectures other than MIPS go one step further by having an even more limited getrlimit system call, so arm and x86 need to use ugetrlimit instead of getrlimit. Worse, the 32-bit architectures don't have 64-bit getrlimit- and setrlimit-equivalent system calls, and you have to use prlimit64 instead. There's no 32-bit prlimit system call, so there's no easy implementation of that --- what should we do if the result of prlimit64 won't fit in a struct rlimit? Since 32-bit survived without prlimit/prlimit64 for this long, I'm not going to bother implementing prlimit for 32-bit. We need the rlimit64 functions to be able to build strace 4.8 out of the box.

Fix build by avoiding the _C_LABEL macro. Change-Id: Ide367c2b65071388bd95fbc81a4ed6ae94aec4e4 2014-02-19 01:42:36 +01:00			`.globl getrlimit64`
