Subject: [PATCH 0/4] apply page shift to PFN instead of VA in pfn_to_virt
Date: Wed, 31 Jan 2024 13:51:59 +0800
Message-Id: <20240131055159.2506-1-yan.y.zhao@intel.com>
Precedence: bulk

This is a tiny fix to pfn_to_virt() for some platforms.

The original implementaion of pfn_to_virt() takes PFN instead of PA as the
input to macro __va, with PAGE_SHIFT applying to the converted VA, which
is not right under most conditions, especially when there's an offset in
__va.


Yan Zhao (4):
  asm-generic/page.h: apply page shift to PFN instead of VA in
    pfn_to_virt
  csky: apply page shift to PFN instead of VA in pfn_to_virt
  Hexagon: apply page shift to PFN instead of VA in pfn_to_virt
  openrisc: apply page shift to PFN instead of VA in pfn_to_virt
