From 52f993b8e89487ec9ee15a7fb4979e0f09a45b27 Mon Sep 17 00:00:00 2001 From: Yunhong Jiang Date: Wed, 8 Mar 2017 23:13:28 -0800 Subject: Upgrade to 4.4.50-rt62 The current kernel is based on rt kernel v4.4.6-rt14. We will upgrade it to 4.4.50-rt62. The command to achieve it is: a) Clone a git repo from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git b) Get the diff between this two changesets: git diff 640eca2901f3435e616157b11379d3223a44b391 705619beeea1b0b48219a683fd1a901a86fdaf5e where the two commits are: [yjiang5@jnakajim-build linux-stable-rt]$ git show --oneline --name-only 640eca2901f3435e616157b11379d3223a44b391 640eca2901f3 v4.4.6-rt14 localversion-rt [yjiang5@jnakajim-build linux-stable-rt]$ git show --oneline --name-only 705619beeea1b0b48219a683fd1a901a86fdaf5e 705619beeea1 Linux 4.4.50-rt62 localversion-rt c) One patch has been backported thus revert the patch before applying. filterdiff -p1 -x scripts/package/Makefile ~/tmp/v4.4.6-rt14-4.4.50-rt62.diff |patch -p1 --dry-run Upstream status: backport Change-Id: I244d57a32f6066e5a5b9915f9fbf99e7bbca6e01 Signed-off-by: Yunhong Jiang --- kernel/include/linux/spinlock_rt.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'kernel/include/linux/spinlock_rt.h') diff --git a/kernel/include/linux/spinlock_rt.h b/kernel/include/linux/spinlock_rt.h index 3b2825537..7eb87584e 100644 --- a/kernel/include/linux/spinlock_rt.h +++ b/kernel/include/linux/spinlock_rt.h @@ -26,6 +26,7 @@ extern void __lockfunc rt_spin_lock(spinlock_t *lock); extern unsigned long __lockfunc rt_spin_lock_trace_flags(spinlock_t *lock); extern void __lockfunc rt_spin_lock_nested(spinlock_t *lock, int subclass); extern void __lockfunc rt_spin_unlock(spinlock_t *lock); +extern int __lockfunc rt_spin_unlock_no_deboost(spinlock_t *lock); extern void __lockfunc rt_spin_unlock_wait(spinlock_t *lock); extern int __lockfunc rt_spin_trylock_irqsave(spinlock_t *lock, unsigned long *flags); extern int __lockfunc rt_spin_trylock_bh(spinlock_t *lock); @@ -112,6 +113,7 @@ static inline unsigned long spin_lock_trace_flags(spinlock_t *lock) #define spin_lock_nest_lock(lock, nest_lock) spin_lock_nested(lock, 0) #define spin_unlock(lock) rt_spin_unlock(lock) +#define spin_unlock_no_deboost(lock) rt_spin_unlock_no_deboost(lock) #define spin_unlock_bh(lock) \ do { \ -- cgit 1.2.3-korg
