glibc: Drop upstream rejected patchesjansa/sumo
These patches were applied, hoping that they will eventually be accepted upstream but they have been rejected, I think its best that they are dropped so we can avoid novel unintended behaviours that no other distros will be seeing Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

-Subject: [PATCH 26/27] reset dl_load_write_lock after forking
-
-The patch in this Bugzilla entry was requested by a customer:
-
- https://www.sourceware.org/bugzilla/show_bug.cgi?id=19282
-
-The __libc_fork() code reset dl_load_lock, but it also needed to reset
-dl_load_write_lock. The patch has not yet been integrated upstream.

-Upstream-Status: Pending [ No Author See bugzilla]

-Subject: [PATCH 27/27] Acquire ld.so lock before switching to malloc_atfork
-
-The patch is from
- https://sourceware.org/bugzilla/show_bug.cgi?id=4578
-
-If a thread happens to hold dl_load_lock and have r_state set to RT_ADD or
-RT_DELETE at the time another thread calls fork(), then the child exit code
-from fork (in nptl/sysdeps/unix/sysv/linux/fork.c in our case) re-initializes
-dl_load_lock but does not restore r_state to RT_CONSISTENT. If the child
-subsequently requires ld.so functionality before calling exec(), then the
-assertion will fire.
-
-The patch acquires dl_load_lock on entry to fork() and releases it on exit
-from the parent path. The child path is initialized as currently done.
-This is essentially pthreads_atfork, but forced to be first because the
-acquisition of dl_load_lock must happen before malloc_atfork is active
-to avoid a deadlock.
-
-The patch has not yet been integrated upstream.
