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) [1] https://lore.kernel.org/linuxppc-dev/5501ba80-bdb0-6344-16b0-0466a950f82c@xxxxxxxx/ 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(-) base-commit: f8d21cb17a99b75862196036bb4bb93ee9637b74 -- 2.42.0
