Subject: [GIT PULL] alpha updates for v7.3
Date: Tue, 18 Aug 2026 20:29:22 +0200 [thread overview]
Message-ID: <aoSkgrrgIY29ioTS@z440.darklands.se> (raw)
Hi Linus,
This pull request contains two fixes for Alpha floating-point exception
handling, two clang-related fixes, the preparatory changes from the
generic-entry series, an interrupt-entry lockdep fix, two Marvel/EV7 IRQ
fixes, an RTC fix, and one header cleanup.
The generic-entry preparation adds regset-based ptrace and core dumps,
ARCH_STACKWALK and lockdep hardirq-state tracking. These changes are
useful independently and enable previously missing debugging facilities
on Alpha.
The final patch switching Alpha to GENERIC_ENTRY is intentionally not
included in this pull request. I am deferring that change to allow
further testing and to reduce the risk of conflicts with ongoing
entry-path work elsewhere in the kernel.
The following changes since commit dc59e4fea9d83f03bad6bddf3fa2e52491777482:
