Linux Kernel Daily: AMD Fixes Converge Ahead of 7.3
This cycle's merges were dominated by AMD-specific corrections, including an inverted interrupt bug in machine check storm handling and a null pointer risk in the AMD node driver, alongside a batch of powerpc entry and interrupt fixes. Both AMD issues are tagged for stable backport.

Good day. It's September 9th, 2026, and this is Linux Kernel Daily.
Today's activity is light on volume but heavy on AMD-specific corrections, with a secondary thread of powerpc entry and exception handling fixes rolling in ahead of 7.3.
Start with AMD. Commit d292911 fixes a genuinely backwards bit of logic in the machine check storm handler: the code was enabling threshold interrupts when a storm was detected, and disabling them when it subsided — the exact opposite of what storm handling requires. That's the kind of bug that quietly defeats the…
Right alongside it, commit aefdbd5 addresses a null pointer risk in the AMD node driver. A prior reordering of initialization left a redundant exclusivity flag in place while the real safety check — verifying the AMD roots pointer isn't null — went missing. Jason Andryuk's fix replaces the stale flag with a direct…
Second theme: powerpc. Madhavan Srinivasan's pull, folded into merge 5acbae5, bundles a set of entry and interrupt fixes — clearing a stale syscall return flag before error returns, preserving restore-all state across syscall restarts, and fixing interrupt soft-mask corruption on replayed interrupt exit. These are…
Smaller but…
