Hi Linus,
Late in the cycle, but this has fixes for couple of issues: a PAE40 boot crash and
Arnd spotting lack of barriers in BE io-accessors. The 3rd patch for enabling
highmem in low physical mem ;-) honestly is more than a "fix" but its been in
works for some time, seems to be stable in testing and enables 2 of our customers
to go forward with 4.6 kernel.
Please pull !
Thx,
-Vineet
