[Linux-Xtensa] [PULL 0/7] xtensa fixes and improvements for 3.16

[Max Filippov]

Hi Chris,

please pull this series of fixes for xtensa for v3.16. It is based on v3.15.
I was hoping to make a fix for HIGHMEM on cores with aliasing cache for 3.16
but since it requires changes to the core kernel code it will only make it
into 3.17 (in the best case).

The following changes since commit 1860e379875dfe7271c649058aeddffe5afd9d0d:

  Linux 3.15 (2014-06-08 11:19:54 -0700)
