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 [thread overview]
Message-ID: <20240131055159.2506-1-yan.y.zhao@intel.com> (raw)
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
