Subject: [PATCH 0/8] Update kernel uabi header files for x32

X32 uses the same kernel system call interface as x86-64 for many
system calls.  However, "long" is 64-bit for x86-64 and is 32-bit for
x32.  Where long or unsigned long are used in struct types for such
system calls, they are wrong for x32.  __kernel_[u]long_t is [unsigned]
long for all ABIs other than x32.  I am submitting 8 patches to replace
long or unsigned long with __kernel_[u]long_t so that those struct types
can be used with x32 system calls.

H.J. Lu (8):
  Use __kernel_long_t in struct timex
  Use __kernel_long_t/__kernel_ulong_t in <linux/resource.h>
  Use __kernel_ulong_t in uapi struct ipc64_perm
  Use __kernel_long_t in struct msgbuf
  Use __kernel_ulong_t in struct msqid64_ds
  Use __kernel_ulong_t in x86 struct semid64_ds
  Use __kernel_ulong_t in shmid64_ds/shminfo64/shm_info
  Use __kernel_long_t in struct mq_attr
