thunderbolt: Read router NVM version before applying quirks

2026-03-02T06:51:58+00:00

The router NVM version is currently only available after the NVMem devices have been registered. This is too late for firmware-dependent quirks that are evaluated during tb_switch_add() before device registration. Split router NVM handling into two phases: - tb_switch_nvm_init() allocates the NVM object and reads the version - tb_switch_nvm_add() registers the NVMem devices using the pre-read NVM This makes the NVM major/minor version available before tb_check_quirks() without changing when the NVMem devices are registered.

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

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

kernel.h: drop hex.h and update all hex.h users

2026-01-21T03:44:19+00:00

Remove from and update all users/callers of hex.h interfaces to directly #include as part of the process of putting kernel.h on a diet. Removing hex.h from kernel.h means that 36K C source files don't have to pay the price of parsing hex.h for the roughly 120 C source files that need it. This change has been build-tested with allmodconfig on most ARCHes. Also, all users/callers of in the entire source tree have been updated if needed (if not already #included).

thunderbolt: Fix bit masking in tb_dp_port_set_hops()

2025-06-23T09:52:08+00:00

The tb_dp_port_set_hops() function was incorrectly clearing ADP_DP_CS_1_AUX_RX_HOPID_MASK twice. According to the function's purpose, it should clear both TX and RX AUX HopID fields. Replace the first instance with ADP_DP_CS_1_AUX_TX_HOPID_MASK to ensure proper configuration of both AUX directions.
