Subject: [PATCH] Use __kernel_ulong_t in shmid64_ds/shminfo64/shm_info
Date: Wed, 25 Dec 2013 08:53:59 -0800	[thread overview]
Message-ID: <20131225165359.GA29550@gmail.com> (raw)

Both x32 and x86-64 use the same struct shmid64_ds/shminfo64/shm_info for
system calls.  But x32 long is 32-bit. This patch replaces unsigned long
with __kernel_ulong_t in struct shmid64_ds/shminfo64/shm_info.
