fbdev: au1100fb: Fix build on MIPS64

2026-03-05T16:35:12+00:00

Fix an error reported by the kernel test robot: au1100fb.c: error: implicit declaration of function 'KSEG1ADDR'; did you mean 'CKSEG1ADDR'? arch/mips/include/asm/addrspace.h defines KSEG1ADDR only for 32 bit configurations. So provide its compile-test stub also for 64bit mips builds. Fixes: 6f366e86481a ("fbdev: au1100fb: Make driver compilable on non-mips platforms") Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202603042127.PT6LuKqi-lkp@intel.com/ Signed-off-by: Helge Deller Acked-by: Uwe Kleine-König

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

Convert 'alloc_flex' family to use the new default GFP_KERNEL argument

2026-02-22T01:09:51+00:00

This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'. Signed-off-by: Linus Torvalds

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

fbdev: au1100fb: Replace license boilerplate by SPDX header

2026-02-19T16:38:17+00:00

This also gets rid of an old address of the FSF. Signed-off-by: Uwe Kleine-König Signed-off-by: Helge Deller

fbdev: au1100fb: Fold au1100fb.h into its only user

2026-02-19T16:38:17+00:00

This gets rid of a header that is only used once. The copyrights and license specifications are all already covered in the au1100fb.c file. Signed-off-by: Uwe Kleine-König Signed-off-by: Helge Deller

fbdev: au1100fb: Replace custom printk wrappers by pr_*

2026-02-19T16:38:17+00:00

The global wrappers also have the advantage to do stricter format checking, so the pr_devel formats are also checked if DEBUG is not defined. The global variants only check for DEBUG being defined and not its actual value, so the #define to zero is dropped, too. There is only a slight semantic change as the (by default disabled) debug output doesn't contain __FILE__ any more. Signed-off-by: Uwe Kleine-König Signed-off-by: Helge Deller

fbdev: au1100fb: Make driver compilable on non-mips platforms

2026-02-19T16:38:17+00:00

The header asm/mach-au1x00/au1000.h is unused apart from pulling in (for mdelay()) and (for KSEG1ADDR()). Then the only platform specific part in the driver is the usage of the KSEG1ADDR macro, which for the non-mips case can be stubbed. Signed-off-by: Uwe Kleine-König Signed-off-by: Helge Deller

fbdev: au1100fb: Use proper conversion specifiers in printk formats

2026-02-19T16:38:17+00:00

%zu is the dedicated type for size_t. %d only works on 32bit architectures where size_t is typedef'd to be unsigned int. (And then the signedness doesn't fit, but `gcc -Wformat` doesn't stumble over this. Also the size of dma_addr_t is architecture dependent and it should be printkd using %pad (and the value passed by reference). This prepares allowing this driver to be compiled on non-mips platforms.
