Hi Linus,
please pull some important fixes for the parisc architecture from:
git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-4.6-3
Since commit 0de7985 (parisc: Use generic extable search and sort routines)
module loading is boken on parisc, because the parisc module loader wasn't
prepared for the new R_PARISC_PCREL32 relocations.
In addition, due to that breakage, Mikulas Patocka noticed that handling
exceptions from modules probably never worked on parisc. It was just masked by
the fact that exceptions from modules don't happen during normal use.
This patch series fixes those issues and survives the tests of the
lib/test_user_copy kernel module test. Some patches are tagged for stable.
Thanks,
Helge
