2007-10-11[MIPS] ARC: Get rid of mips_machgroupRalf Baechle1-2/+0
This has not been any serious user of this ill conceived thing since the original invention in like '95. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-07-10[MIPS] Add some debugfs files to debug unaligned accessesAtsushi Nemoto1-0/+16
Currently a number of unaligned instructions is counted but not used. Add /debug/mips/unaligned_instructions file to show the value. And add /debug/mips/unaligned_action to control behavior upon an unaligned access. Possible actions are: 0: silently fixup the unaligned access. 1: send SIGBUS. 2: dump registers, process name, etc. and fixup.

2007-02-06[MIPS] FLATMEM: introduce PHYS_OFFSET.Franck Bui-Huu1-4/+8
The old code was assuming that min_low_pfn was always 0. This means that platforms having a big hole at their memory start paid the price of wasting some memory for the allocation of unused entries in mem_map[]. This patch prevents this waste. It introduces PHYS_OFFSET define which is the start of the physical memory and uses it wherever needed. Specially when converting physical/virtual addresses into virtual/physical ones. Currently all platforms defines PHYS_OFFSET to 0. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-02-06[MIPS] Setup min_low_pfn/max_low_pfn correctlyFranck Bui-Huu1-9/+27
This patch makes a better usage of these two globals. 'min_low_pfn' is now correctly setup for all configs, which allow us to rely on it in boot memory code init. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2006-09-27[MIPS] setup.c: use early_param() for early command line parsingFranck Bui-Huu1-112/+60
There's no point to rewrite some logic to parse command line to pass initrd parameters or to declare a user memory area. We could use instead parse_early_param() that does the same thing. Signed-off-by: Franck Bui-Huu <vagabon.xyz@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2006-09-27[MIPS] setup.c: cleanup bootmem_init()Franck Bui-Huu1-78/+57
This function although doing simple thing is hard to follow. It's mainly due to: - a lot of #ifdef - bad local names - redundant tests So this patch try to address these issues. It also do not use max_pfn global which is marked as an unused exported symbol. As a bonus side, it's now really easy to see what part of the code is for no-numa system. There's also no point to make this function inline. Signed-off-by: Franck Bui-Huu <vagabon.xyz@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2006-07-10[PATCH] tty: Remove include of screen_info.h from tty.hJon Smirl1-1/+1
screen_info.h doesn't have anything to do with the tty layer and shouldn't be included by tty.h. This patches removes the include and modifies all users to directly include screen_info.h. struct screen_info is mainly used to communicate with the console drivers in drivers/video/console. Note that this patch touches every arch and I have no way of testing it. If there is a mistake the worst thing that will happen is a compile error.

2006-06-29[MIPS] Only register RAM as resources if UNCAC_BASE != IO_BASE.Ralf Baechle1-0/+3

2006-06-19[MIPS] Cleanup memory managment initialization.Ralf Baechle1-13/+43
Historically plat_mem_setup did the entire platform initialization. This was rather impractical because it meant plat_mem_setup had to get away without any kind of memory allocator. To keep old code from breaking plat_setup was just renamed to plat_setup and a second platform initialization hook for anything else was introduced. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2006-06-06[MIPS] Fix sparsemem support.Chad Reese1-2/+1
Move memory_present() in arch/mips/kernel/setup.c. When using sparsemem extreme, this function does an allocate for bootmem. This would always fail since init_bootmem hasn't been called yet. Move memory_present after free_bootmem. This only marks actual memory ranges as present instead of the entire address space.

2006-03-27[PATCH] unify PFN_* macrosDave Hansen1-8/+1
Just about every architecture defines some macros to do operations on pfns. They're all virtually identical. This patch consolidates all of them. One minor glitch is that at least i386 uses them in a very skeletal header file. To keep away from #include dependency hell, I stuck the new definitions in a new, isolated header. Of all of the implementations, sh64 is the only one that varied by a bit. It used some masks to ensure that any sign-extension got ripped away before the arithmetic is done. This has been posted to that sh64 maintainers and the development list. Compiles on x86, x86_64, ia64 and ppc64.

2006-02-27[MIPS] SMP: Fix initialization order bug.Ralf Baechle1-0/+3
A recent change requires cpu_possible_map to be initialized before smp_sched_init() but most MIPS platforms were initializing their processors in the prom_prepare_cpus callback of smp_prepare_cpus. The simple fix of calling prom_prepare_cpus from one of the earlier SMP initialization hooks doesn't work well either since IPIs may require init_IRQ() to have completed, so bit the bullet and split prom_prepare_cpus into two initialization functions, plat_smp_setup which is called early from setup_arch and plat_prepare_cpus called where prom_prepare_cpus used to be called.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+571
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
