clkdev: remove CONFIG_CLKDEV_LOOKUP

2024-12-14T18:47:46Z

[ Upstream commit 2f4574dd6dd19eb3e8ab0415a3ae960d04be3a65 ] This option is now synonymous with CONFIG_HAVE_CLK, so use the latter globally. Any out-of-tree platform ports that still use a private clk_get()/clk_put() implementation should move to CONFIG_COMMON_CLK.

commit 01eb454e9bfe593f320ecbc9aaec60bf87cd453d upstream check_bugs() is about to be phased out. Switch over to the new arch_cpu_finalize_init() implementation. No functional change.

seccomp: Move config option SECCOMP to arch/Kconfig

2020-10-08T20:17:47Z

In order to make adding configurable features into seccomp easier, it's better to have the options at one single location, considering especially that the bulk of seccomp code is arch-independent. An quick look also show that many SECCOMP descriptions are outdated; they talk about /proc rather than prctl. As a result of moving the config option and keeping it default on, architectures arm, arm64, csky, riscv, sh, and xtensa did not have SECCOMP on by default prior to this and SECCOMP will be default in this change. Architectures microblaze, mips, powerpc, s390, sh, and sparc have an outdated depend on PROC_FS and this dependency is removed in this change.

uaccess: add infrastructure for kernel builds with set_fs()

2020-09-09T02:21:32Z

Add a CONFIG_SET_FS option that is selected by architecturess that implement set_fs, which is all of them initially. If the option is not set stubs for routines related to overriding the address space are provided so that architectures can start to opt out of providing set_fs.

sh: switch to copy_thread_tls()

2020-08-15T02:05:18Z

Use the copy_thread_tls() calling convention which passes tls through a register. This is required so we can remove the copy_thread{_tls}() split and remove the HAVE_COPY_THREAD_TLS macro.

sh: use the generic dma coherent remap allocator

2020-08-15T02:05:18Z

This switches to using common code for the DMA allocations, including potential use of the CMA allocator if configured. Switching to the generic code enables DMA allocations from atomic context, which is required by the DMA API documentation, and also adds various other minor features drivers start relying upon. It also makes sure we have on tested code base for all architectures that require uncached pte bits for coherent DMA allocations. Signed-off-by: Christoph Hellwig Signed-off-by: Rich Felker
