[PATCH] Documentation: coding-style: don’t encourage WARN*() (Alex Elder)

https://lkml.kernel.org/r/20240414170850.148122-1-elder@linaro.org

Due to the panic_on_warn setting, even WARN() and its friends are not that welcomed in multiple situations. Alex posted a patchset to make this point clearer.

[PATCH 0/5] mm: code and data partitioning improvements (Maxwell Bland)

https://lkml.kernel.org/r/20240416122254.868007168-1-mbland@motorola.com

Because of ASLR requirements and static VMALLOC_START/VMALLOC_END, managing allocations for ensuring uninterleaved code/data pages is impossible. It results in inefficient page table modifications due to the fact the individual PTE update is required. This patch adds minimal arch-specific hooks that can be used to mitigate the problem.

Below is the diffstat of the releases in the last two years.
