Subject: [GIT PULL] parisc architecture fixes for kernel v5.8
Date: Sun, 26 Jul 2020 21:14:04 +0200 [thread overview]
Message-ID: <20200726191404.GA10491@ls3530.fritz.box> (raw)
Hi Linus,
please pull two late parisc architecture fixes for kernel 5.8 from:
git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-5.8-2
Two fixes:
- Add the cmpxchg() function for pointers to u8 values. This fixes a kernel
linking error when building the tusb1210 driver (from Liam Beguin).
- Add a define for atomic64_set_release() to fix CPU soft lockups which happen
because of missing unlocks while processing bit operations (from John David
Anglin).
Thanks,
Helge
