Re: [PATCH v4 0/5] ppc, fbdev: Clean up fbdev mmap helper
Ping for a review. I'd like to get at least the first two patches into the DRM git tree. The PPC patches could later be merged through another tree.

[PATCH v4 0/5] ppc, fbdev: Clean up fbdev mmap helper
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. v4: * fix commit message (Christophe) v3: * rename fb_pgrotect() to pgprot_framebuffer() (Arnd) v2: * reorder patches to simplify merging (Michael) [1] https://lore.kernel.org/linuxppc-dev/5501ba80-bdb0-6344-16b0-0466a950f...@suse.com/ Thomas Zimmermann (5): fbdev: Avoid file argument in fb_pgprotect() fbdev: Replace fb_pgprotect() with pgprot_framebuffer() arch/powerpc: Remove trailing whitespaces arch/powerpc: Remove file parameter from phys_mem_access_prot code arch/powerpc: Call internal __phys_mem_access_prot() in fbdev code arch/ia64/include/asm/fb.h| 15 +++ arch/m68k/include/asm/fb.h| 19 ++- arch/mips/include/asm/fb.h| 11 +-- arch/powerpc/include/asm/book3s/pgtable.h | 10 -- arch/powerpc/include/asm/fb.h | 13 + arch/powerpc/include/asm/machdep.h| 13 ++--- arch/powerpc/include/asm/nohash/pgtable.h | 10 -- arch/powerpc/include/asm/pci.h| 4 +--- arch/powerpc/kernel/pci-common.c | 3 +-- arch/powerpc/mm/mem.c | 8 arch/sparc/include/asm/fb.h | 15 +-- arch/x86/include/asm/fb.h | 10 ++ arch/x86/video/fbdev.c| 15 --- drivers/video/fbdev/core/fb_chrdev.c | 3 ++- include/asm-generic/fb.h | 12 ++-- 15 files changed, 86 insertions(+), 75 deletions(-) -- 2.42.0
