I'm pleased to announce the v5.9-rc8-rt12 patch set. Changes since v5.9-rc8-rt11: - The kernel test robot reported a few warnings due to the printk code and a compile error in the powerpc architecture. Known issues - It has been pointed out that due to changes to the printk code the internal buffer representation changed. This is only an issue if tools like `crash' are used to extract the printk buffer from a kernel memory image. The delta patch against v5.9-rc8-rt11 is appended below and can be found here: https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.9/incr/patch-5.9-rc8-rt11-rt12.patch.xz You can get this release via the git tree at: git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git v5.9-rc8-rt12 The RT patch against v5.9-rc8 can be found here: https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.9/older/patch-5.9-rc8-rt12.patch.xz The split quilt queue is available at: https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.9/older/patches-5.9-rc8-rt12.tar.xz Sebastian diff --git a/arch/powerpc/kexec/crash.c b/arch/powerpc/kexec/crash.c index c9a889880214e..d488311efab1f 100644 --- a/arch/powerpc/kexec/crash.c +++ b/arch/powerpc/kexec/crash.c @@ -311,9 +311,6 @@ void default_machine_crash_shutdown(struct pt_regs *regs) unsigned int i; int (*old_handler)(struct pt_regs *regs); - /* Avoid hardlocking with irresponsive CPU holding logbuf_lock */ - printk_nmi_enter(); - /* * This function is only called after the system * has panicked or is otherwise in a critical state. diff --git a/kernel/printk/printk.c b/kernel/printk/printk.c index 8b74ff17b2eef..ee7008c436ca1 100644 --- a/kernel/printk/printk.c +++ b/kernel/printk/printk.c @@ -1981,12 +1981,6 @@ asmlinkage int vprintk(const char *fmt, va_list args) } EXPORT_SYMBOL(vprintk); -int vprintk_default(const char *fmt, va_list args) -{ - return vprintk_emit(0, LOGLEVEL_DEFAULT, NULL, 0, fmt, args); -} -EXPORT_SYMBOL_GPL(vprintk_default); - /** * printk - print a kernel message * @fmt: format string @@ -2784,7 +2778,7 @@ static int __init init_printk_kthread(void) } late_initcall(init_printk_kthread); -static int vprintk_deferred(const char *fmt, va_list args) +__printf(1, 0) static int vprintk_deferred(const char *fmt, va_list args) { return vprintk_emit(0, LOGLEVEL_DEFAULT, NULL, 0, fmt, args); } diff --git a/localversion-rt b/localversion-rt index 05c35cb580779..6e44e540b927b 100644 --- a/localversion-rt +++ b/localversion-rt @@ -1 +1 @@ --rt11 +-rt12
