Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise.

The first one by Huacai Chen addresses a runtime warning when CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS are selected which occurs because the cpuinfo code on sh incorrectly uses NR_CPUS when iterating CPUs instead of the runtime limit nr_cpu_ids. A second fix by Dan Carpenter fixes a use-after-free bug in register_intc_controller() which occurred as a result of improper error handling in the interrupt controller driver code when registering an interrupt controller during plat_irq_setup() on sh" * tag 'sh-for-v6.13-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux: sh: intc: Fix use-after-free bug in register_intc_controller() sh: cpuinfo: Fix a warning for CONFIG_CPUMASK_OFFSTACK 2024-11-30T12:54:36Z Huacai Chen chenhuacai@loongson.cn 2022-07-14T08:41:36Z urn:sha1:3c891f7c6a4e90bb1199497552f24b26e46383bc When CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS are selected, cpu_max_bits_warn() generates a runtime warning similar as below when showing /proc/cpuinfo.

The VDSO data page handling is architecture specific for historical reasons, but there is no real technical reason to do so. Aside of that VDSO data has become a dump ground for various mechanisms and fail to provide a clear separation of the functionalities. Clean this up by: - consolidating the VDSO page data by getting rid of architecture specific warts especially in x86 and PowerPC. - removing the last includes of header files which are pulling in other headers outside of the VDSO namespace. - seperating timekeeping and other VDSO data accordingly.
