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

parisc: Move init function declarations into header file

Clean up the code to not have external function declarations inside the C source files. Reduces warnings when compiled with W=1. Signed-off-by: Helge Deller

parisc: Fix CPU affinity for Lasi, WAX and Dino chips

2022-03-29T19:37:12+00:00

Add the missing logic to allow Lasi, WAX and Dino to set the CPU affinity. This fixes IRQ migration to other CPUs when a CPU is shutdown which currently holds the IRQs for one of those chips. Signed-off-by: Helge Deller

remove ioremap_nocache and devm_ioremap_nocache

ioremap has provided non-cached semantics by default since the Linux 2.6 days, so remove the additional ioremap_nocache interface. Signed-off-by: Christoph Hellwig Acked-by: Arnd Bergmann

parisc: Disable HP HSC-PCI Cards to prevent kernel crash

2019-09-08T13:43:04+00:00

The HP Dino PCI controller chip can be used in two variants: as on-board controller (e.g. in B160L), or on an Add-On card ("Card-Mode") to bridge PCI components to systems without a PCI bus, e.g. to a HSC/GSC bus. One such Add-On card is the HP HSC-PCI Card which has one or more DEC Tulip PCI NIC chips connected to the on-card Dino PCI controller. Dino in Card-Mode has a big disadvantage: All PCI memory accesses need to go through the DINO_MEM_DATA register, so Linux drivers will not be able to use the ioremap() function. Without ioremap() many drivers will not work, one example is the tulip driver which then simply crashes the kernel if it tries to access the ports on the HP HSC card. This patch disables the HP HSC card if it finds one, and as such fixes the kernel crash on a HP D350/2 machine. Signed-off-by: Helge Deller Noticed-by: Phil Scarr Cc: stable@vger.kernel.org
