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

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

clocksource/drivers/imx: Fix -Wunused-but-set-variable warning

2024-01-22T12:11:02+00:00

All warnings (new ones prefixed by >>): drivers/clocksource/timer-imx-gpt.c: In function 'mxc_timer_interrupt': >> drivers/clocksource/timer-imx-gpt.c:279:18: warning: variable 'tstat' set but not used [-Wunused-but-set-variable] 279 | uint32_t tstat; | ^~~~~ vim +/tstat +279 drivers/clocksource/timer-imx-gpt.c The change remove the tstats assignment but not the reading of the register, assuming the register may be a ROR (Reset On Read) which happens in the driver's interrupt registers.

clocksource/drivers/imx-gpt: Use only a single name for functions

2023-06-19T15:31:56+00:00

When looking at the data structs defining the different behaviours of the GPT blocks in different SoCs it's not helpful that the same functions are used with different names. So drop the cpp defines and use the original names. This commit was generated using: perl -i -e 'my %m; while (<>) { if (/^#define (imx[a-zA-Z0-6_]*)\s(imx[a-zA-Z0-6_]*)/) {$m{$1} = $2; } else { foreach my $f (keys %m) {s/$f/$m{$f}/; } print; } }' drivers/clocksource/timer-imx-gpt.c This patch has no effect on the generated code.

clocksource: Replace setup_irq() by request_irq()

2020-02-27T11:15:24+00:00

request_irq() is preferred over setup_irq(). The early boot setup_irq() invocations happen either via 'init_IRQ()' or 'time_init()', while memory allocators are ready by 'mm_init()'. Per tglx[1], setup_irq() existed in olden days when allocators were not ready by the time early interrupts were initialized. Hence replace setup_irq() by request_irq(). Seldom remove_irq() usage has been observed coupled with setup_irq(), wherever that has been found, it too has been replaced by free_irq(). A build error that was reported by kbuild test robot in the previous version of the patch also has been fixed.
