mm: remove xlate_dev_kmem_ptr()

2021-05-07T07:26:34Z

Since /dev/kmem has been removed, let's remove the xlate_dev_kmem_ptr() leftovers.

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.

MIPS: Loongson64: Enlarge IO_SPACE_LIMIT

mips: io.h: delete duplicated word

MIPS: move ioremap_prot und iounmap out of line

2020-04-19T14:12:31Z

Neither of these interfaces is anywhere near the fast path. Move them out of line and avoid exposing implementation details to the drivers. Signed-off-by: Christoph Hellwig Signed-off-by: Thomas Bogendoerfer

MIPS: split out the 64-bit ioremap implementation

2020-04-19T14:11:08Z

Split out the mips64 ioremap implementation entirely, as it will never use page table based remapping. Signed-off-by: Christoph Hellwig Signed-off-by: Thomas Bogendoerfer

MIPS: merge __ioremap_mode into ioremap_prot

2020-04-19T14:10:24Z

There is no reason to have two ioremap with flags interfaces. Merge the historic mips __ioremap_mode into ioremap_prot which is a generic kernel interface. Signed-off-by: Christoph Hellwig Signed-off-by: Thomas Bogendoerfer

MIPS: remove cpu_has_64bit_addresses

2020-04-19T14:08:29Z

This macro is identical to CONFIG_64BIT, and using a Kconfig variable for the only places that checks them (the ioremap implementation) will simplify later patches in this series. Signed-off-by: Christoph Hellwig Signed-off-by: Thomas Bogendoerfer

remove ioremap_nocache and devm_ioremap_nocache

2020-01-06T08:45:59Z

ioremap has provided non-cached semantics by default since the Linux 2.6 days, so remove the additional ioremap_nocache interface. Signed-off-by: Christoph Hellwig Acked-by: Arnd Bergmann

MIPS: define ioremap_nocache to ioremap

2020-01-06T08:43:14Z

They are both defined the same way, but this makes it easier to validate the scripted ioremap_nocache removal following soon. Signed-off-by: Christoph Hellwig Acked-by: Paul Burton
