[linux-yocto][v5.15/standard/preempt-rt/sdkv5.15/xlnx-soc][PATCH] driver: soc: xilinx: rename cpu_number1 to dummy_cpu_number
From: Quanyang Wang
The per cpu variable cpu_number1 is passed to xlnx_event_handler as
argument "dev_id", but is not used in this function. So drop the
initialization of this variable and rename it to dummy_cpu_number.
This patch is to fix the following calltrace when the kernel option
CONFIG_DEBUG_ATOMIC_SLEEP is enabled:
BUG: sleeping function called from invalid context at

have the document and not figure out how to set the HDMI audio parameters
for the BBB target board, to avoid below booting error information if

[linux-yocto][yocto-kernel-cache][yocto-6.1 master][PATCH 0/1] feature/security: add configs to harden protection
From: Xiangyu Chen Hi Bruce, After using kernel-hardening-checker[1] utils to check current configs, we picked up some configs from failure case to feature/security/security.cfg to improve the kernel security. Following configs no impact on performance but can improve kernel security: CONFIG_HW_RANDOM_TPM=y Exposing the TPM's Random Number Generator(if have) as a hwrng device. CONFIG_DEBUG_WX=y Warn on W+X mappings at boot. CONFIG_SECURITY_DMESG_RESTRICT=y Restrict unprivileged access to the kernel syslog. CONFIG_LDISC_AUTOLOAD=n Disable automatically load TTY Line Disciplines. Thanks!

We can resolve most of them by favoring the SDK version. However, there are some that need to be handled with extra care. There are only 5 patches in the v6.1.73, so there is no any conflict when merging it. All the branches have passed my build test. I have pushed all these branches to: https://github.com/haokexin/linux You can use this as a reference for the linux-yocto stable kernel bump.
