[PATCHv6 0/4] glibc tunables

[Siddhesh Poyarekar <siddhesh at sourceware dot org>]

Hi,

Here is iteration 6 of the tunables patchset, now with two patches palmed off
to Adhemerval to worry about!  Here are changes from the previous patchset:

 - I discovered some implicit includes that broke aarch64 - shame on me for
   missing them.
 - I realized that __tunables_init used strncmp and strlen.  They're built into
   ld.so too, but they are likely tunables targets and I don't want them to
   break unintentionally in future, so off they go
 - The patchset depends on Adhemerval's __access_noerrno patch[1] fixed up with
   my comments on the patch.

The branch siddhesh/tunables has these patches and also Adhemerval's fixed up
patch.  If you're watching this, please also review Adhemerval's
__access_noerrno patch and help get that through.
