Merge tag 'timers-vdso-2024-11-18' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull vdso data page handling updates from Thomas Gleixner: "First steps of consolidating the VDSO data page handling. 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. Further consolidation of the VDSO page handling is done in subsequent changes scheduled for the next merge window. This also lays the ground for expanding the VDSO time getters for independent PTP clocks in a generic way without making every architecture add support seperately" * tag 'timers-vdso-2024-11-18' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (42 commits) x86/vdso: Add missing brackets in switch case vdso: Rename struct arch_vdso_data to arch_vdso_time_data powerpc: Split systemcfg struct definitions out from vdso powerpc: Split systemcfg data out of vdso data page powerpc: Add kconfig option for the systemcfg page powerpc/pseries/lparcfg: Use num_possible_cpus() for potential processors powerpc/pseries/lparcfg: Fix printing of system_active_processors powerpc/procfs: Propagate error of remap_pfn_range() powerpc/vdso: Remove offset comment from 32bit vdso_arch_data x86/vdso: Split virtual clock pages into dedicated mapping x86/vdso: Delete vvar.h x86/vdso: Access vdso data without vvar.h x86/vdso: Move the rng offset to vsyscall.h x86/vdso: Access rng vdso data without vvar.h x86/vdso: Access timens vdso data without vvar.h x86/vdso: Allocate vvar page from C code x86/vdso: Access rng data from kernel without vvar x86/vdso: Place vdso_data at beginning of vvar page x86/vdso: Use __arch_get_vdso_data() to access vdso data x86/mm/mmap: Remove arch_vma_name() ...
