MIPS: Remove empty prom_free_prom_memory functions

2021-01-07T16:11:33Z

Most of the prom_free_prom_memory functions are empty. With a new weak prom_free_prom_memory() we can remove all of them. Signed-off-by: Thomas Bogendoerfer Acked-by: Florian Fainelli

MIPS: replace add_memory_region with memblock

2020-10-12T10:01:36Z

add_memory_region was the old interface for registering memory and was already changed to used memblock internaly. Replace it by directly calling memblock functions. Signed-off-by: Thomas Bogendoerfer

mm: don't include asm/pgtable.h if linux/mm.h is already included

2020-06-09T16:39:13Z

Patch series "mm: consolidate definitions of page table accessors", v2. The low level page table accessors (pXY_index(), pXY_offset()) are duplicated across all architectures and sometimes more than once. For instance, we have 31 definition of pgd_offset() for 25 supported architectures. Most of these definitions are actually identical and typically it boils down to, e.g. static inline unsigned long pmd_index(unsigned long address) { return (address >> PMD_SHIFT) & (PTRS_PER_PMD - 1); } static inline pmd_t *pmd_offset(pud_t *pud, unsigned long address) { return (pmd_t *)pud_page_vaddr(*pud) + pmd_index(address); } These definitions can be shared among 90% of the arches provided XYZ_SHIFT, PTRS_PER_XYZ and xyz_page_vaddr() are defined. For architectures that really need a custom version there is always possibility to override the generic version with the usual ifdefs magic. These patches introduce include/linux/pgtable.h that replaces include/asm-generic/pgtable.h and add the definitions of the page table accessors to the new header. This patch (of 12): The linux/mm.h header includes to allow inlining of the functions involving page table manipulations, e.g. pte_alloc() and pmd_alloc(). So, there is no point to explicitly include in the files that include . The include statements in such cases are remove with a simple loop: for f in $(git grep -l "include ") ; do sed -i -e '/include / d' $f done Signed-off-by: Mike Rapoport Signed-off-by: Andrew Morton Cc: Arnd Bergmann Cc: Borislav Petkov Cc: Brian Cain Cc: Catalin Marinas Cc: Chris Zankel Cc: "David S.

MIPS: fw: arc: add __weak to prom_meminit and prom_free_prom_memory

2020-04-08T15:13:45Z

As far as I understood, prom_meminit() in arch/mips/fw/arc/memory.c is overridden by the one in arch/mips/sgi-ip32/ip32-memory.c if CONFIG_SGI_IP32 is enabled. The use of EXPORT_SYMBOL in static libraries potentially causes a problem for the llvm linker [1]. So, I want to forcibly link lib-y objects to vmlinux when CONFIG_MODULES=y. As a groundwork, we must fix multiple definitions that have previously been hidden by lib-y. The prom_cleanup() in this file is already marked as __weak (because it is overridden by the one in arch/mips/sgi-ip22/ip22-mc.c). I think it should be OK to do the same for these two.

MIPS: SGI-IP22/28: Use PROM for memory detection

2019-10-09T21:55:57Z

EARLY_PRINTK uses ArcWrite (via prom_putchar) on IP22/28, which needs to not mess up PROMs data structures. ARC PROM gives out a list of memory chunks, which are used and which are free. This fixes the problem of not working early printk. By using XKPHYS spaces more than 256MB memory on Indigo2 R4k machines is working now, too.
