Subject: [PATCH v5 0/5] ppc, fbdev: Clean up fbdev mmap helper
Date: Fri, 22 Sep 2023 10:04:54 +0200 [thread overview]
Message-ID: <20230922080636.26762-1-tzimmermann@suse.de> (raw)
Clean up and rename fb_pgprotect() to work without struct file. Then
refactor the implementation for PowerPC. This change has been discussed
at [1] in the context of refactoring fbdev's mmap code.
The first two patches update fbdev and replace fbdev's fb_pgprotect()
with pgprot_framebuffer() on all architectures. The new helper's stream-
lined interface enables more refactoring within fbdev's mmap
implementation.
Patches 3 to 5 adapt PowerPC's internal interfaces to provide
phys_mem_access_prot() that works without struct file. Neither the
architecture code or fbdev helpers need the parameter.
v5:
* improve commit descriptions (Javier)
* add missing tags (Geert)
v4:
* fix commit message (Christophe)
v3:
* rename fb_pgrotect() to pgprot_framebuffer() (Arnd)
v2:
* reorder patches to simplify merging (Michael)
