MIPS: Refactor 'clear_page' and 'copy_page' functions.

2017-10-12T14:27:21Z

commit c022630633624a75b3b58f43dd3c6cc896a56cff upstream. Remove usage of the '__attribute__((alias("...")))' hack that aliased to integer arrays containing micro-assembled instructions. This hack breaks when building a microMIPS kernel. It also makes the code much easier to understand. [ralf@linux-mips.org: Added back export of the clear_page and copy_page symbols so certain modules will work again. Also fixed build with CONFIG_SIBYTE_DMA_PAGEOPS enabled.] Signed-off-by: Steven J.

MIPS: Move arch_get_unmapped_area and gang to new file.

2011-05-19T08:55:49Z

It never really belonged into syscall.c and it's about to become well more complex. Signed-off-by: Ralf Baechle

MIPS: Kconfig and Makefile update for Netlogic XLR/XLS

Add NLM_XLR_BOARD, CPU_XLR and other config options Makefile updates, mostly based on r4k Signed-off-by: Jayachandran C To: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/2334/ Signed-off-by: Ralf Baechle

MIPS: Add -Werror to arch/mips/Kbuild

2010-08-05T12:25:44Z

Adding subdirs-ccflags-y := -Werror to arch/mips/Kbuild let us in one go cover all files with -Werror. In addition this allows us to remove the individual -Werror definition in various Makefile. Adding the definition to Kbuild as a recursive option help us not to forget to do so. With this change we now compile arch/mips/kernel/cpufreq with -Werror One drawback: When specifying a subdirectory covered by the Kbuild file like this: make arch/mips/kernel/ then kbuild fails to pick up the -Werror definition.

MIPS: Hook up Cavium OCTEON in arch/mips.

2009-01-11T09:57:22Z

Take all the OCTEON specific files that were added, and hook them into the build system for the arch/mips. For versions of GCC that lack OCTEON support, override gas target architecture. Signed-off-by: Tomaso Paoletti Signed-off-by: David Daney Signed-off-by: Ralf Baechle

MIPS: Add CONFIG_CPU_R5500 for NEC VR5500 series processors

2008-10-27T16:18:29Z

We already have sufficient infrastructure to support VR5500 and VR5500A series processors. Here's a Makefile support to make it selectable by ports, and enable it for NEC EMMA2RH Markeins board. This patch also fixes a confused target help, and adds 1Gb PageMask bits supported by VR5500 and its variants. Signed-off-by: Shinya Kuribayashi Signed-off-by: Ralf Baechle

mips: use generic show_mem()

2008-07-26T19:00:11Z

Remove arch-specific show_mem() in favor of the generic version. This also removes the following redundant information display: - pages in swapcache, printed by show_swap_cache_info() where show_mem() calls show_free_areas(), which calls show_swap_cache_info(). And show_mem() does now actually print something on configurations with multiple nodes.

[MIPS] Reimplement clear_page/copy_page

2008-04-28T16:14:23Z

Fold the SB-1 specific implementation of clear_page/copy_page in the generic version, and rewrite that one in tlbex style. The immediate benefits: - It converts the compile-time workaround for SB-1 pass 1 prefetches to a more efficient run-time check. - It allows adjustment of loop unfolling, which helps to reduce the number of redundant cdex cache ops. - It fixes some esoteric cornercases (the cache line length calculations can go wrong, and support for 64k pages without prefetch instructions will overflow the addiu immediate). - Somewhat better guesses of "good" prefetch values.

[MIPS] Split the micro-assembler from tlbex.c.

2008-02-01T14:48:44Z

This patch moves the micro-assembler in a separate implementation, as it is useful for further run-time optimizations. The only change in behaviour is cutting down printk noise at kernel startup time. Checkpatch complains about macro parameters which aren't protected by parentheses. I believe this is a flaw in checkpatch, the paste operator used in those macros won't work with parenthesised parameters. Signed-off-by: Thiemo Seufer Signed-off-by: Ralf Baechle
