Pull sh fix from John Paul Adrian Glaubitz:
 "The ZERO_PAGE consolidation in v7.1, introduced a regression on sh
  which made these systems unbootable.

  The problem was that on sh, the initial boot parameters were
  previously referenced as an array and after 6215d9f4470f ("arch, mm:
  consolidate empty_zero_page"), they were referenced as a pointer which
  caused wrong code generation and boot hang.

  This changes the declaration back to being an array which fixes the
  boot hang"

   fair scheduler (Peter Zijlstra)

 - Fix wakeup_preempt_fair() to do proper delayed dequeue
   (Vincent Guittot)

 - Clear sched_entity::rel_deadline when initializing
   forked entities, which bug can cause all tasks to be
   EEVDF-ineligible, causing a NULL pointer dereference
   crash in pick_next_entity() (Zicheng Qu)

Consolidation of empty_zero_page declarations broke boot on sh.

sh stores its initial boot parameters in a page reserved in
arch/sh/kernel/head_32.S. Before commit 6215d9f4470f ("arch, mm:
consolidate empty_zero_page") this page was referenced in C code
as an array and after that commit it is referenced as a pointer.

This causes wrong code generation and boot hang.

Declare boot_params_page as an array to fix the issue.

Pull arm64 fixes from Catalin Marinas:

 - Avoid writing an uninitialised stack variable to POR_EL0 on sigreturn
   if the poe_context record is absent

 - Reserve one more page for the early 4K-page kernel mapping to cover
   the extra [_text, _stext) split introduced by the non-executable
   read-only mapping

 - Force the arch_local_irq_*() wrappers to be __always_inline so that
   noinstr entry and idle paths cannot call out-of-line, instrumentable
   copies

 - Fix potential sign extension in the arm64 SCS unwinder's DWARF
   advance_loc4 decoding

 - Tolerate arm64 ACPI platforms with only WFI and no deeper PSCI idle
   states, restoring cpuidle registration on such systems

 - Include the UAPI <asm/ptrace.h> header in the arm64 GCS libc test
   rather than carrying a duplicate struct user_gcs definition (the
   original #ifdef NT_ARM_GCS was wrong to cover the structure
   definition as it would be masked out if the toolchain defined it)
