Pull 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"

alpha: enable lockdep hardirq state tracking

Alpha masks interrupts through the PAL IPL state, so lockdep cannot infer
hardirq state transitions from generic code alone. Add explicit
hardirq on/off annotations to the low-level entry and return paths so
lockdep's IRQ state follows the hardware IPL state.

Annotate the PAL IPL transitions and the shared return-to-user/kernel
paths where interrupts become enabled or disabled. With the preceding
irqflags, raw-lock, sysfs, and ftrace return-address preparations in
place, select LOCKDEP_SUPPORT and TRACE_IRQFLAGS_SUPPORT for Alpha.

This keeps CONFIG_PROVE_LOCKING usable on Alpha instead of disabling
debug_locks due to IRQ-state mismatches.

alpha: add ARCH_STACKWALK-based stacktrace support

Implement arch_stack_walk() for Alpha using a simple kernel
stack scanning walker. Start from regs+1 for current tasks
to skip pt_regs and use pcb.ksp for blocked tasks. Filter
candidates with __kernel_text_address() and stop at stack
bounds via kstack_end().

Enable CONFIG_STACKTRACE_SUPPORT and CONFIG_ARCH_STACKWALK
so generic stacktrace users (dump_stack(), /proc/*/stack,
SysRq backtraces, etc.) work on Alpha.

This provides functional in-kernel stack traces without
requiring frame pointer unwinding.

alpha: enable regset-based ptrace and core dumps

Add a user_regset_view for Alpha and switch ELF core dumping to
CORE_DUMP_USE_REGSET. General-purpose registers are exported in
ELF gregs layout, including callee-saved registers and a correct
user stack pointer.

The user stack pointer is not preserved in pt_regs on Alpha, so expose
it from the PCB, or via rdusp() for the current task, when building the
ELF register image. This makes the user stack pointer consistent for
core 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 the
ELF-visible register layouts, while the common ptrace regset code handles
PTRACE_GETREGSET and PTRACE_SETREGSET iovec semantics. This avoids
duplicating subtle short-buffer and oversized-buffer behavior in
arch_ptrace().

With these changes Alpha satisfies the requirements for
HAVE_ARCH_TRACEHOOK and selects it, enabling generic tracehook and
ptrace syscall-info code paths without changing the existing syscall
entry ABI.

alpha: add support for SECCOMP and SECCOMP_FILTER

Add SECCOMP and SECCOMP_FILTER support to the Alpha architecture and fix
syscall entry and ptrace issues uncovered by the seccomp-bpf selftests.

The syscall entry path is reworked to consistently track syscall state
using r0, r1 and r2:
- r1 holds the active syscall number
- r2 preserves the original syscall number for restart
- r0 carries the return value, with r19 (a3) indicating success/error

This allows syscall restarts to be permitted only for valid ERESTART*
return codes and prevents kernel-internal restart values from leaking to
userspace. The syscall tracing error marker is corrected to use the saved
syscall number slot, matching the Alpha ABI.

Additionally, implement minimal PTRACE_GETREGSET and PTRACE_SETREGSET
support for NT_PRSTATUS, exporting struct pt_regs directly. This fixes
ptrace-based seccomp tests that previously failed with -EIO.

With these changes, seccomp-bpf and ptrace syscall tests pass reliably on
Alpha.
