Merge tag 'alpha-for-v7.3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/lindholm/alphaPull alpha updates from Magnus Lindholm: "This 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"* tag 'alpha-for-v7.3-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/lindholm/alpha: alpha: read $gp and $sp explicitly for clang alpha: pass -Wa,-mev6 only when using GNU as alpha: annotate hardirqs-off on IPL 7 interrupt entry alpha: run the remote RTC access in a worker, not an IPI callback alpha: don't leak hardware-fabricated FP exception bits to user space alpha: fix ieee_swcr_to_fpcr setting FPCR_DNOD unconditionally alpha: enable lockdep hardirq state tracking alpha: use raw spinlocks for low-level platform locks alpha: provide ftrace return address support for lockdep alpha: make irqflags helpers operate on IPL state alpha: add ARCH_STACKWALK-based stacktrace support alpha: enable regset-based ptrace and core dumps alpha: marvel: Fix lock ordering in init_io7_irqs() alpha: marvel: Fix irq_set_status_flags to use correct IRQ number alpha: remove unnecessary architecture-specific List of files: /linux/arch/alpha/Kconfig

Mon, 06 Jul 2026 18:56:47 +0200

alpha: enable lockdep hardirq state trackingAlpha masks interrupts through the PAL IPL state, so lockdep cannot inferhardirq state transitions from generic code alone. Add explicithardirq on/off annotations to the low-level entry and return paths solockdep's IRQ state follows the hardware IPL state.Annotate the PAL IPL transitions and the shared return-to-user/kernelpaths where interrupts become enabled or disabled. With the precedingirqflags, raw-lock, sysfs, and ftrace return-address preparations inplace, select LOCKDEP_SUPPORT and TRACE_IRQFLAGS_SUPPORT for Alpha.This keeps CONFIG_PROVE_LOCKING usable on Alpha instead of disablingdebug_locks due to IRQ-state mismatches.Reviewed-by: Matt Turner Tested-by: Matt Turner Signed-off-by: Magnus Lindholm Link: https://lore.kernel.org/r/20260706170019.2941459-7-linmag7@gmail.comSigned-off-by: Magnus Lindholm List of files: /linux/arch/alpha/Kconfig

46651c650facce7cac33610ccc7a07a9c9d90df4 - alpha: add ARCH_STACKWALK-based stacktrace support

Mon, 06 Jul 2026 18:56:43 +0200

alpha: add ARCH_STACKWALK-based stacktrace supportImplement arch_stack_walk() for Alpha using a simple kernelstack scanning walker. Start from regs+1 for current tasksto skip pt_regs and use pcb.ksp for blocked tasks. Filtercandidates with __kernel_text_address() and stop at stackbounds via kstack_end().Enable CONFIG_STACKTRACE_SUPPORT and CONFIG_ARCH_STACKWALKso generic stacktrace users (dump_stack(), /proc/*/stack,SysRq backtraces, etc.) work on Alpha.This provides functional in-kernel stack traces withoutrequiring frame pointer unwinding.Reviewed-by: Matt Turner Tested-by: Matt Turner Signed-off-by: Magnus Lindholm Link: https://lore.kernel.org/r/20260706170019.2941459-3-linmag7@gmail.comSigned-off-by: Magnus Lindholm List of files: /linux/arch/alpha/Kconfig

8a2857bc2b3039eef6c15900b00424417a2293e8 - alpha: enable regset-based ptrace and core dumps

Mon, 06 Jul 2026 18:56:42 +0200

alpha: enable regset-based ptrace and core dumpsAdd a user_regset_view for Alpha and switch ELF core dumping toCORE_DUMP_USE_REGSET. General-purpose registers are exported inELF gregs layout, including callee-saved registers and a correctuser stack pointer.The user stack pointer is not preserved in pt_regs on Alpha, so exposeit from the PCB, or via rdusp() for the current task, when building theELF register image. This makes the user stack pointer consistent forcore dumps, ptrace regsets, and PTRACE_GET_SYSCALL_INFO.Implement regset get/set callbacks for both NT_PRSTATUS and NT_PRFPREG.The callbacks translate between Alpha's pt_regs/thread state and theELF-visible register layouts, while the common ptrace regset code handlesPTRACE_GETREGSET and PTRACE_SETREGSET iovec semantics. This avoidsduplicating subtle short-buffer and oversized-buffer behavior inarch_ptrace().With these changes Alpha satisfies the requirements forHAVE_ARCH_TRACEHOOK and selects it, enabling generic tracehook andptrace syscall-info code paths without changing the existing syscallentry ABI.Reviewed-by: Matt Turner Tested-by: Matt Turner Signed-off-by: Magnus Lindholm Link: https://lore.kernel.org/r/20260706170019.2941459-2-linmag7@gmail.comSigned-off-by: Magnus Lindholm List of files: /linux/arch/alpha/Kconfig
