vdso: Introduce vdso/page.h

2024-10-15T22:13:04Z

The VDSO implementation includes headers from outside of the vdso/ namespace. Introduce vdso/page.h to make sure that the generic library uses only the allowed namespace.

arch: consolidate existing CONFIG_PAGE_SIZE_*KB definitions

2024-03-06T18:28:26Z

These four architectures define the same Kconfig symbols for configuring the page size. Move the logic into a common place where it can be shared with all other architectures. Reviewed-by: Thomas Gleixner Signed-off-by: Arnd Bergmann

mm, arch: add generic implementation of pfn_valid() for FLATMEM

2023-02-10T00:51:41Z

Every architecture that supports FLATMEM memory model defines its own version of pfn_valid() that essentially compares a pfn to max_mapnr. Use mips/powerpc version implemented as static inline as a generic implementation of pfn_valid() and drop its per-architecture definitions.

mm: replace CONFIG_NEED_MULTIPLE_NODES with CONFIG_NUMA

2021-06-29T17:53:55Z

After removal of DISCINTIGMEM the NEED_MULTIPLE_NODES and NUMA configuration options are equivalent. Drop CONFIG_NEED_MULTIPLE_NODES and use CONFIG_NUMA instead. Done with $ sed -i 's/CONFIG_NEED_MULTIPLE_NODES/CONFIG_NUMA/' \ $(git grep -wl CONFIG_NEED_MULTIPLE_NODES) $ sed -i 's/NEED_MULTIPLE_NODES/NUMA/' \ $(git grep -wl NEED_MULTIPLE_NODES) with manual tweaks afterwards.

MIPS: Add support for CONFIG_DEBUG_VIRTUAL

2021-04-06T12:34:02Z

Provide hooks to intercept bad usages of virt_to_phys() and __pa_symbol() throughout the kernel. To make this possible, we need to rename the current implement of virt_to_phys() into __virt_to_phys_nodebug() and wrap it around depending on CONFIG_DEBUG_VIRTUAL. A similar thing is needed for __pa_symbol() which is now aliased to __phys_addr_symbol() whose implementation is either the direct return of RELOC_HIDE or goes through the debug version.
