commit: https://git.buildroot.net/buildroot/commit/?id=f8d0d28bf9d9e931509cc4a38936bc118e801808
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

- Rebase patches from 2.25 on top of 2.26.
- Use git format for patches
- remove upstreamed xtensa patches

The first patch [1] is needed to be able to build glibc with binutils 2.26 on nios2.
The second from [2] fix an assertion issue with ld.

+Subject: [PATCH] sh-conf
+
+Likewise, binutils has no idea about any of these new targets either, so we
+fix that up too.. now we're able to actually build a real toolchain for
+sh2a_nofpu- and other more ineptly named toolchains (and yes, there are more
+inept targets than that one, really. Go look, I promise).

+Subject: [PATCH] xtensa: fix signedness of gas relocations
+
+Change 1058c7532d0b "Use signed data type for R_XTENSA_DIFF* relocation
+offsets." changed signedness of BFD_RELOC_XTENSA_DIFF* relocations
+substituted for BFD_RELOC_*. This made it impossible to encode arbitrary
+8-, 16- and 32-bit values, which broke e.g. debug info encoding by .loc
+directive. Revert this part and add test.
+
+gas/
+2016-02-03  Max Filippov  <jcmvbkbc at gmail.com>
+	* config/tc-xtensa.c (md_apply_fix): Mark BFD_RELOC_XTENSA_DIFF*
+	substitutions for BFD_RELOC_* as unsigned.
+
+gas/testsuite/
+2016-02-03  Max Filippov  <jcmvbkbc at gmail.com>
+	* gas/xtensa/all.exp: Add loc to list of xtensa tests.
+	* gas/xtensa/loc.d: New file: loc test result patterns.
+	* gas/xtensa/loc.s: New file: loc test.
