Hi Linus,
please pull the latest updates and fixes for the parisc architecture.
There is one noteable patch, which allows the parisc kernel to use the same
MADV_xxx constants as the other architectures going forward. With that change
only alpha has one entry left (MADV_DONTNEED is 6 vs 4 on others) which is
different. To prevent an ABI breakage, a wrapper is included which translates
old MADV values to the new ones, so existing userspace isn't affected.
Reason for that patch is, that some applications wrongly used the standard
MADV_xxx values even on some non-x86 platforms and as such those
programs failed to run correctly on parisc (examples are qemu-user, tor
browser and boringssl).
Then the kgdb console and the LED code received some fixes, and some
0-day warnings are now gone. Finally, the very last compile warning
which was visible during a kernel build is now fixed too (in the vDSO
code).
The majority of the patches are tagged for stable series and in summary
this patchset is quite small and drops more code than it adds.
Thanks!
Helge
