[PATCH v2 1/2] arm64: dts: rockchip: Move uart5 pin configuration to SoM dtsi

by Lukasz Czechowski

In the PX30-uQ7 (Ringneck) SoM, the hardware CTS and RTS pins for uart5 cannot be used for the UART CTS/RTS, because they are already allocated for different purposes. CTS pin is routed to SUS_S3# signal, while RTS pin is used internally and is not available on Q7 connector. Move definition of the pinctrl-0 property from px30-ringneck-haikou.dts to px30-ringneck.dtsi. This commit is a dependency to next commit in the patch series, that disables DMA for uart5.

NULL pointer dereference in apparmor's profile_transition v6.12

by Paul Kramme

Hello, with v6.12 we encountered a kernel BUG (panic on our systems) that is caused by a NULL pointer dereference inside the apparmor's profile_transition code. I've contacted John Johansen as the maintainer for the apparmor system, and he pointed me to 17d0d04f3c99 as a fix for that issue. That commit has now landed in v6.13, would it be possible to backport this to v6.12? Commit is 17d0d04f3c99 apparmor: allocate xmatch for nullpdb inside aa_alloc_null Thanks, Paul

[PATCH 2/2] atomic64: Use arch_spin_locks instead of raw_spin_locks

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> raw_spin_locks can be traced by lockdep or tracing itself. Atomic64 operations can be used in the tracing infrastructure. When an architecture does not have true atomic64 operations it can use the generic version that disables interrupts and uses spin_locks. The tracing ring buffer code uses atomic64 operations for the time keeping. But because some architectures use the default operations, the locking inside the atomic operations can cause an infinite recursion. As atomic64 is an architecture specific operation, it should not be using raw_spin_locks() but instead arch_spin_locks as that is the purpose of arch_spin_locks. To be used in architecture specific implementations of generic infrastructure like atomic64 operations.
