Hi, Guys
There was a discussion about bump vdso version of kernel. We need
update the vdso version in glibc correspondingly otherwise the
application could not make use of the vdso.
Is it make sense to you?
Regards
Bamvor

This series enables aarch64 port with ilp32 mode.
ABI details:
- types are taken from AARCH32, next types turned to 64-bit,
as modern requirement for new APIs tells:
ino_t is u64 type
off_t is s64 type
blkcnt_t is s64 type
fsblkcnt_t is u64 type
fsfilcnt_t is u64 type
- 64-bit arguments are passed in syscall as register pair,
as kernel internally clears top halves for all input regs;
- standard syscall table is used;
- 32-bit time_t is used. AARCH64/ILP32 is waiting for general
fix of Y2038 problem just like other 32-bit arches;
- stat{64}, statfs{64} structures are of the identical layout
with LP64. Corresponding syscalls are taken from 64-bit code
- struct utmp, utmpx layouts are the same.
v1: https://sourceware.org/ml/libc-alpha/2016-06/msg00730.html
v2:
- rebased on master;
- dropped unneeded/unrelated patches;
- pread family platform implementation removed;
- addressed v1 comments (I'm really sorry if I missed something,
there are a lot of them, and I am really thankfull for detailed review);
Tested with LTP. Regressions are like this:
abort01 FAIL 2
kill11 FAIL 2
mmap16 FAIL 6
open12 FAIL 2
rename11 FAIL 2
rmdir02 FAIL 2
umount2_01 FAIL 2
umount2_02 FAIL 2
umount2_03 FAIL 2
utime06 FAIL 2
It's better than v1, and there are ~5 additional regressions comparing to
aarch64, all are related to filesystem.

[AARCH64] define word size for lp64 and ilp32
[AARCH64] Add header guards to sysdep.h headers.
Add dynamic ILP32 AARCH64 relocations to elf.h

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] Add ILP32 support to elf_machine_load_address.
[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] Make lp64 and ilp32 directories.
[AARCH64] Fix ILP32 warning
Yury Norov (6):
[AARCH64] ILP32: introduce syscalls that pass off_t
[AARCH64] ILP32: support stat syscall family
[AARCH64] delouse input arguments in system functions
