Linus,

Please pull these RISC-V updates for v7.0-rc7.  These are all
relatively minor functional fixes.  The branch was recently rebuilt, but
only to remove fixes that aren't critical at this point in the release
cycle.

thanks,

- Paul

  ACPI: RIMT: Add dependency between iommu and devices (2026-04-04 18:38:03 -0600)

----------------------------------------------------------------
RISC-V updates for v7.0-rc7

- Fix a CONFIG_SPARSEMEM crash on RV32 by avoiding early phys_to_page()

- Prevent runtime const infrastructure from being used by modules, similar
  to what was done for x86

- Avoid problems when shutting down ACPI systems with IOMMUs by adding
  a device dependency between IOMMU and devices that use it

- Fix a bug where the CPU pointer masking state isn't properly reset
  when tagged addresses aren't enabled for a task

- Fix some incorrect register assignments, and add some missing ones,
  in kgdb support code

- Fix compilation of non-kernel code that uses the ptrace uapi header
  by replacing BIT() with _BITUL()

- Fix compilation of the validate_v_ptrace kselftest by working around
  kselftest macro expansion issues
