2014-10-14 David S. Miller <davem@davemloft.net>
* sanitizer_common/sanitizer_platform_limits_linux.cc (time_t):
Define at __kernel_time_t, as needed for sparc.
(struct __old_kernel_stat): Don't check if __sparc__ is defined.
* libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.h
(__sanitizer): Define struct___old_kernel_stat_sz,
struct_kernel_stat_sz, and struct_kernel_stat64_sz for sparc.
(__sanitizer_ipc_perm): Adjust for sparc targets.
(__sanitizer_shmid_ds): Likewsie.
(__sanitizer_sigaction): Likewsie.
(IOC_SIZE): Likewsie.
