18d4371683 hppa: add fanotify_mark
Another example of all the 64bit arches getting the definition via a
common file, but the 32bit ones all adding it by themselves and hppa
was missed.

I'm not entirely sure about the usage of GLIBC_2.19 symbols here.
We'd like to backport this so people can use it, but it means we'd
be releasing a glibc-2.17/glibc-2.18 with a GLIBC_2.19 symbol in it.
But maybe it won't be a big deal since you'd only get that 2.19 ref
if you actually used the symbol ?

There hasn't been a glibc release where hppa worked w/out a bunch of
patches, so in reality there's only two distros that matter -- Gentoo
and Debian.

6b06ac56cd ARM: Fix clone code when built for Thumb.
The mov lr, pc instruction will lose the Thumb bit from the return address
so use blx lr instead.

b72ca61b71 MIPS: Correct the handling of reserved FCSR bits
Reserved bits in the Floating-Point Control and Status Register (FCSR)
should not be implicitly cleared by fedisableexcept or feenableexcept,
there is no reason to.  Among these are the 8 condition codes and one of
the two bits reserved for architecture implementers (bits #22 & #21).

As to the latter, there is no reason to treat any of them as reserved
either, they should be user controllable and settable via __fpu_control
override as the user sees fit.  For example in processors implemented by
MIPS Technologies, such as the 5Kf or the 24Kf, these bits are used to
change the treatment of denormalised operands and tiny results: bit #22
is Flush Override (FO) and bit #21 is Flush to Nearest (FN).  They cause
non-IEEE-compliant behaviour, but some programs may have a use for such
modes of operation; the library should not obstruct such use just as it
does not for the architectural Flush to Zero (FS) bit (bit #24).

Therefore the change adjusts the reserved mask accordingly and also
documents the distinction between bits 22:21 and 20:18.

1fe2988f52 tile BZ #15759: Fix bug in _dl_unmap
We returned without calling __munmap if not in the simulator.
Now we call a separate sim_dlclose() function to make the
control flow work correctly.

properly initializing the variable pagesize in certain cases.  This
change just copies the existing code from MIPS.

fe114d2064 _dl_static_init: Remove nested locking.
This function is now called from dl_open_worker with the GL(dl_load_lock)
lock held and no longer needs local protection.  GL(dl_load_lock) also
correctly protects _dl_lookup_symbol_x called here that relies on the
caller to have serialized access to the data structures it uses.
