MIPS: BCM77xx: Remove legacy __cpuinit{,data} sections that crept in

2015-06-21T19:53:42+00:00

We removed __cpuinit support (leaving no-op stubs) quite some time ago. However a few more crept in as of commit 6ee1d93455384cef8a0426effe85da2 ("MIPS: BCM47XX: Detect more then 128 MiB of RAM (HIGHMEM)") Since we want to clobber the stubs soon, get this removed now.

MIPS: Add support for XPA.

2015-03-19T16:39:49+00:00

Add support for extended physical addressing (XPA) so that 32-bit platforms can access equal to or greater than 40 bits of physical addresses. NOTE: 1) XPA and EVA are not the same and cannot be used simultaneously. 2) If you configure your kernel for XPA, the PTEs and all address sizes become 64-bit. 3) Your platform MUST have working HIGHMEM support.

mm: make FIRST_USER_ADDRESS unsigned long on all archs

2015-02-12T01:06:03+00:00

LKP has triggered a compiler warning after my recent patch "mm: account pmd page tables to the process": mm/mmap.c: In function 'exit_mmap': >> mm/mmap.c:2857:2: warning: right shift count >= width of type [enabled by default] The code: > 2857 WARN_ON(mm_nr_pmds(mm) > 2858 round_up(FIRST_USER_ADDRESS, PUD_SIZE) >> PUD_SHIFT); In this, on tile, we have FIRST_USER_ADDRESS defined as 0. round_up() has the same type -- int. PUD_SHIFT. I think the best way to fix it is to define FIRST_USER_ADDRESS as unsigned long. On every arch for consistency. Signed-off-by: Kirill A.

mips: drop _PAGE_FILE and pte_file()-related helpers

2015-02-10T22:30:32+00:00

We've replaced remap_file_pages(2) implementation with emulation. Nobody creates non-linear mapping anymore. Signed-off-by: Kirill A. Shutemov Cc: Ralf Baechle Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

MIPS: Cosmetic cleanups of page table headers.

2014-11-24T21:47:31+00:00

* Clean up white spaces and tabs. * Remove _PAGE_R4KBUG which is no longer used. * Get rid of hardcoded values and calculate shifts and masks where possible. Signed-off-by: Steven J.

MIPS: BCM47XX: Detect more then 128 MiB of RAM (HIGHMEM)

2014-07-30T21:27:02+00:00

So far BCM47XX can only detect amount of HIGHMEM. It still requires adding (registering) and well-testing before enabling by default.

Revert "MIPS: Delete unused function add_temporary_entry."

2014-07-30T21:27:02+00:00

This reverts commit d7a887a73dec6c387b02a966a71aac767bbd9ce6. Function add_temporary_entry is needed by bcm47xx to support highmem. We need to add a temporary entry to check for amount of RAM. The only change made in this revert was replacing (ENTER|EXIT)_CRITICAL.

MIPS: Whitespace cleanup.

2013-02-01T09:00:22+00:00

Having received another series of whitespace patches I decided to do this once and for all rather than dealing with this kind of patches trickling in forever. Signed-off-by: Ralf Baechle
