[PATCH 00/29] Add Support for AARCH64:ILP32

[Andrew Pinski <apinski at cavium dot com>]

This patch series adds AARCH64:ILP32 support to glibc.
The first patch fixes a bug and it should go in even without the rest
of the patches being approved.

The next 6 patches are common/generic changes to allow AARCH64 to
use the generic headers rather than a copy of its own.

The next patch just adds header guards which is needed to make
sure sysdep.h is not included twice.

The next one adds the relocations to elf.h; these relocations are defined
in the beta version of the ABI.

Then the rest of the patches fully add support for ILP32, split up for easier
review.

I have ran LTO on with the kernel changes that were submitted (but not committed)
and there was no unexpected failures (there are a few testcase issues dealing with
sigaction strcuture not being the same between the kernel and the userland).

Andrew Pinski (29):
  [AARCH64] Fix utmp struct for compatibility reasons.
  Allow sigset be an array of a different type
  Add ability for the IPC structures (msqid_ds, semid_ds, shmid_ds,
    etc.) to have time_t being 64bit
  Allow rusage work on a big-endian 32bit-on-64bit target
  Allow fd_mask type not be an array of long.
  Allow some fields of siginfo to be different from the generic one
  Allow generic stat and statfs not have padding for 32bit targets
  [AARCH64] Add header guards to sysdep.h headers.
  Add dynamic ILP32 AARCH64 relocations to elf.h
  [AARCH64] Add PTR_REG, PTR_LOG_SIZE, and PTR_SIZE.  Use it in
    LDST_PCREL and LDST_GLOBAL.
  [AARCH64] Use PTR_REG in crti.S.
  [AARCH64] Use PTR_REG/PTR_SIZE/PTR_SIZE_LOG in dl-tlsesc.S
  [AARCH64] Use PTR_* macros in dl-trampoline.S
  [AARCH64] Use PTR_* in start.S
  [AARCH64] Use PTR_REG in getcontext.S.
  [AARCH64] Detect ILP32 in configure scripts.
  [AARCH64] Syscalls for ILP32 are passed always via 64bit values.
  [AARCH64] Reformat inline-asm in elf_machine_load_address.
  [AARCH64] Add ILP32 support to elf_machine_load_address.
  [AARCH64] Set up wordsize for ILP32.
  [AARCH64] Add ILP32 to makefiles
  [AARCH64] Add support to ldconfig for ILP32 and libilp32
  [AARCH64] Add ILP32 ld.so to the known interpreter names.
  [AARCH64] Add ldd-rewrite.sed so that ilp32 ld.so can be found
  [AARCH64] Add kernel_sigaction.h for AARCH64 ILP32
  [AARCH64] Add sigstack.h header for ILP32 reasons.
  [AARCH64] Fix up ucontext for ILP32
  [AARCH64] Add typesizes.h for ILP32
  [AARCH64] Make lp64 and ilp32 directories.
