mn10300: Remove the architecture

2018-03-09T22:19:56+00:00

Remove the MN10300 arch as the hardware is defunct. Suggested-by: Arnd Bergmann Signed-off-by: David Howells cc: Masahiro Yamada cc: linux-am33-list@redhat.com Signed-off-by: Arnd Bergmann

Replace with globally

2016-12-24T19:46:01+00:00

This was entirely automated, using the script by Al: PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*' sed -i -e "s!$PATT!#include !" \ $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h) to do the replacement at the end of the merge window.

mm: concentrate modification of totalram_pages into the mm core

2013-07-03T23:07:33+00:00

Concentrate code to modify totalram_pages into the mm core, so the arch memory initialized code doesn't need to take care of it. With these changes applied, only following functions from mm core modify global variable totalram_pages: free_bootmem_late(), free_all_bootmem(), free_all_bootmem_node(), adjust_managed_page_count(). With this patch applied, it will be much more easier for us to keep totalram_pages and zone->managed_pages in consistence. Signed-off-by: Jiang Liu Acked-by: David Howells Cc: "H.

MN10300: Map userspace atomic op regs as a vmalloc page

2010-10-27T16:28:56+00:00

The AM34 processor has an atomic operation that's the equivalent of LL/SC on other architectures. However, rather than being done through a pair of instructions, it's driven by writing to a pair of memory-mapped CPU control registers. One set of these registers (AARU/ADRU/ASRU) is available for use by userspace, but for userspace to access them a PTE must be set up to cover the region. This is done by dedicating the first vmalloc region page to this purpose, setting the permissions on its PTE such that userspace can access the page. glibc is hardcoded to expect the registers to be there. The way atomic ops are done through these registers is straightforward: (1) Write the address of the word you wish to access into AARU. This causes the CPU to go and fetch that word and load it into ADRU. The status bits are also cleared in ASRU. (2) The current data value is read from the ADRU register and modified. (3) To alter the data in RAM, the revised data is written back to the ADRU register, which causes the CPU to attempt to write it back. (4) The ASRU.RW flag (ASRU read watch), ASRU.LW flag (bus lock watch), ASRU.IW (interrupt watch) and the ASRU.BW (bus error watch) flags then must be checked to confirm that the operation wasn't aborted. If any of the watches have been set to true, the operation was aborted. Signed-off-by: Mark Salter Signed-off-by: David Howells

MN10300: Rename __flush_tlb() to local_flush_tlb()

2010-10-27T16:28:49+00:00

Rename __flush_tlb*() to local_flush_tlb*() as it's more appropriate, and ready to differentiate local from global TLB flushes when SMP is introduced. Whilst we're at it, get rid of __flush_tlb_global() and make local_flush_tlb_page() take an mm_struct pointer rather than VMA pointer. Signed-off-by: David Howells
