I'm announcing the release of the 4.3.5 kernel.
All users of the 4.3 kernel series must upgrade.
The updated 4.3.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.3.y
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary
thanks,
greg k-h

+ help
+ This option adds an alternative code sequence to work around ARM
+ erratum 834220 on Cortex-A57 parts up to r1p2.
+
+ Affected Cortex-A57 parts might report a Stage 2 translation
+ fault as a the result of a Stage 1 fault for a load crossing
+ a page boundary when there is a Stage 1 permission or device
+ memory alignment fault and a Stage 2 translation fault
+
+ The workaround is to verify that the Stage-1 translation
+ doesn't generate a fault before handling the Stage-2 fault.
+ Please note that this does not necessarily enable the workaround,
+ as it depends on the alternative framework, which will only patch
+ the kernel if an affected CPU is detected.
+
+ If unsure, say Y.

Hmm. I may be missing something, but this still doesn't seem to have
commit 23688bf4f830 ("block: ensure to split after potentially
bouncing a bio"). It causes problems on x86-32 with PAE.
See also
https://bugzilla.kernel.org/show_bug.cgi?id=109661
but maybe the fix is there and I just didn't notice.

No, it's not there, it's buried in a ton of other patches I still have
yet to apply to the stable releases. I'll get to them all over the next
week or so. I'll go queue the block ones up later today.
