[Buildroot] [PATCH 0/4] uclibc: build fixes for xtensa snapshot version

[Baruch Siach]

This series adds fixes to the xtensa default uclibc version. The first patch is
not xtensa specific, but the rest are. All patches fix autobuild failures, and
all were sent upstream.

The last patch in this series reverts a previous e2fsprogs fix that is both
wrong and superseded by the xtensa posix_fadvise fix.

Baruch Siach (4):
  uclibc: xtensa: fix posix_spawn autoconf detection
  uclibc: xtensa: restore posix_fadvise
  uclibc: xtensa: update ptrace.h
  Revert "e2fsprogs: fix posix_fadvise() signature mismatch"

[Buildroot] [PATCH 1/4] uclibc: xtensa: fix posix_spawn autoconf detection

[Baruch Siach]

posix_spawn is a new feature in uClibc development branch. Move posix_spawn
implementation from librt to libc so that gnulib can detect it correctly.

[Buildroot] [PATCH 2/4] uclibc: xtensa: restore posix_fadvise

[Baruch Siach]

This is the correct fix to
http://autobuild.buildroot.net/results/79c/79cdb149d349ce9fe2dffbf53e3ff127a050ed24/.
Commit c3d690166c (e2fsprogs: fix posix_fadvise() signature mismatch) fixed the
build failure, but not the underlying problem. The e2fsprogs internal
posix_fadvise() is broken, and upstream has removed it entirely.

[Buildroot] [PATCH 4/4] Revert "e2fsprogs: fix posix_fadvise() signature mismatch"

[Baruch Siach]

This reverts commit c3d690166c4533bc83500a22a43783193fbc27f9.

The real cause of problem is missing posix_fadvise() implementation in uClibc
for xtensa. This has now been fixed in a previous commit. The internal
e2fsprogs posix_fadvise() implementation is broken on 32bit systems anyway, and
upstream has removed it.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-uClibc declares posix_fadvise() even when the architecture does not provide
-one. The static posix_fadvise() signature is not compatible with POSIX. Rename
-the internal implementation to fix this. Fixes the following build failure
-when building against uClibc:
-
-e4defrag.c:189:2: warning: #warning Using locally defined posix_fadvise interface. [-Wcpp]
-e4defrag.c:203:12: error: conflicting types for ?posix_fadvise?
-
-Patch status: sent upstream 
-(http://marc.info/?l=linux-ext4&m=138857218522054&w=2)
