2007-07-10[MIPS] Fix PHYS_OFFSET for 64-bits kernels with 32-bits symbolsFranck Bui-Huu
The current implementation of __pa() for 64-bits kernels with 32-bits symbols is broken. In this configuration, we need 2 values for PAGE_OFFSET, one in XKPHYS and the other in CKSEG0 space. When the value in CKSEG0 space is used, it doesn't take into account of PHYS_OFFSET. Even worse we can't redefine this value. The patch restores CPHYSADDR() but in __pa()'s implementation because it removes the need of 2 PAGE_OFFSET. OTOH, CPHYSADDR() is quite bad when dealing with mapped kernels. So this patch assumes there's no need to deal with such kernel in 64-bits world. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-07-10[MIPS] Make PAGE_OFFSET aware of PHYS_OFFSETFranck Bui-Huu
For platforms that use PHYS_OFFSET and do not use a mapped kernel, this patch automatically adds PHYS_OFFSET into PAGE_OFFSET. Therefore there are no more needs for them to redefine PAGE_OFFSET. For mapped kernel, they need to redefine PAGE_OFFSET anyways. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-07-10[MIPS] Clean up asm-mips/mach-generic/spaces.hFranck Bui-Huu
PAGE_OFFSET definition is now using CAC_BASE by default. This patch also reorder some macros to make them appear in the same order for both 32 and 64 bits configs. It also makes use of const.h generic header file to annotate constants. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-07-10[MIPS] Allow generic spaces.h to be included by platform specific onesFranck Bui-Huu
Before this patch, when a platform needed to customize one constant in spaces.h, they need to redefine all of them. Now they can just redefine one constant and include the generic file header at the end: #include <asm/mach-generic/spaces.h> This patch doesn't allow to redefine CAC_BASE, IO_BASE and UNCAC_BASE for 32 bits platforms because there's no need to do so. This will avoid some macro duplications. It's important specially if we'll add complex macros.

2007-07-06[MIPS] Fix scheduling latency issue on 24K, 34K and 74K coresRalf Baechle
The idle loop goes to sleep using the WAIT instruction if !need_resched(). This has is suffering from from a race condition that if if just after need_resched has returned 0 an interrupt might set TIF_NEED_RESCHED but we've just completed the test so go to sleep anyway. This would be trivial to fix by just disabling interrupts during that sequence as in: local_irq_disable(); if (!need_resched()) __asm__("wait"); local_irq_enable(); but the processor architecture leaves it undefined if a processor calling WAIT with interrupts disabled will ever restart its pipeline and indeed some processors have made use of the freedom provided by the architecture definition. This has been resolved and the Config7.WII bit indicates that the use of WAIT is safe on 24K, 24KE and 34K cores. It also is safe on 74K starting revision 2.1.0 so enable the use of WAIT with interrupts disabled for 74K based on a c0_prid of at least that. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2007-07-06[MIPS] Add macros to encode processor revisions.Ralf Baechle
Older processors used to encode processor version and revision in two 4-bit bitfields, the 4K seems to simply count up and even newer MTI cores have switched to use the 8-bits as 3:3:2 bitfield with the last field as the patch number. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-06-11[MIPS] Fix KMODE for the R3000Maciej W. Rozycki
This must be the oldest bug that we have got. Leaving interrupts "as they are" for the R3000 obviously means copying IEp to IEc. Since we have got STATMASK now, I took this opportunity to mask the status register "correctly" for the R3000 now too. Oh, and the R3000 hardly ever is 64-bit. Signed-off-by: Maciej W.

2007-05-21Detach sched.h from mm.hAlexey Dobriyan
First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%). Cross-compile tested on all arm defconfigs, all mips defconfigs, all powerpc defconfigs, alpha alpha-up arm i386 i386-up i386-defconfig i386-allnoconfig ia64 ia64-up m68k mips parisc parisc-up powerpc powerpc-up s390 s390-up sparc sparc-up sparc64 sparc64-up um-x86_64 x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig as well as my two usual configs.
