This is the start of the stable review cycle for the 3.12.27 release.
There are 104 patches in this series, all will be posted as a response
to this one.  If anyone has any issues with these being applied, please
let me know.

Responses should be made by Fri Aug 22 13:43:20 CEST 2014.
Anything received after that time might be too late.

Build results look good:
	total: 135 pass: 135 fail: 0

qemu tests passed except for sparc64 which hangs during boot, both for SMP and
non-SMP builds. I'll try to bisect as soon as I have a somewhat stable internet
connection.

Reverting the offending patch ('Add basic validations ...') fixes the problem.

Hi,

thanks for the work!

Just note on patches, in 3.12, there are all 3.10 patches plus these three:
+sparc64-add-basic-validations-to-pud-pmd-_bad.patch
+sparc64-fix-executable-bit-testing-in-set_pmd_at-paths.patch
+sparc64-give-more-detailed-information-in-pgd-pmd-_error-and-kill-pte_error.patch

where the third adds only printouts.

These 3.14 patches are not applied to 3.12:
+sparc64-don-t-use-_page_present-in-pte_modify-mask.patch
+sparc64-fix-bugs-in-get_user_pages_fast-wrt.-thp.patch
+sparc64-fix-huge-pmd-invalidation.patch
+sparc64-fix-hex-values-in-comment-above-pte_modify.patch
+sparc64-fix-range-check-in-kern_addr_valid.patch
+sparc64-use-ilog2_4mb-instead-of-constant-22.patch

I tried to apply a couple of those, but they don't apply cleanly.

The last three are just cosmetical in 3.12. And I do not immediately see
in the rest, how they could improve the state. So I am going to remove
the add-basic-validations patch from 3.12.

... so that seems to be the best available solution, at least for now.
