* MIPS: PCI: Move fixups from __init to __devinit.Sebastian Andrzej Siewior2012-07-191-1/+1
| | | | | | | | | | | | | | | | Fixups are executed once the pci-device is found which is during boot process so __init seems fine as long as the platform does not support hotplug. However it is possible to remove the PCI bus at run time and have it rediscovered again via "echo 1 > /sys/bus/pci/rescan" and this will call the fixups again.

* mips: mark const init data with __initconst instead of __initdataUwe Kleine-König2012-07-191-1/+1
| | | | | | | | | | | | | | | | | | | As long as there is no other non-const variable marked __initdata in the same compilation unit it doesn't hurt. If there were one however compilation would fail with error: $variablename causes a section type conflict because a section containing const variables is marked read only and so cannot contain non-const variables.

* MIPS: irq: Remove IRQF_DISABLEDYong Zhang2011-12-071-2/+2
| | | | | | | | | | | | | | | | | | | | Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled], We run all interrupt handlers with interrupts disabled and we even check and yell when an interrupt handler returns with interrupts enabled (see commit [b738a50a: genirq: Warn when handler enables interrupts]). So now this flag is a NOOP and can be removed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 6be63bbbdab66b9185dc6f67c8b1bacb6f37f946 (lmo) rsp. af3a1f6f4813907e143f87030cde67a9971db533 (kernel.org) the Malta code does no longer probe for presence of GCMP if CMP is not configured. This means that the variable gcmp_present well be left at its default value of -1 which normally is meant to indicate that GCMP has not yet been mmapped. This non-zero value is now interpreted as GCMP being present resulting in a write attempt to a GCMP register resulting in a crash.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

| | | | | | | | This is to move the gcmp_probe call to before the use of and selection of the smp_ops functions. This allows malta with 1004K to work. Signed-off-by: Tim Anderson <tanderson@mvista.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* MIPS: CMP: activate CMP supportTim Anderson2009-07-031-0/+10
| | | | | | | | | Most of the CMP support was added before, this mostly correct compile problems but adds a platform specific translation for the interrupt number based on cpu number. Signed-off-by: Tim Anderson <tanderson@mvista.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* MIPS: CMP: Extend IPI handling to CPU numberTim Anderson2009-07-031-38/+36
| | | | | | | | This takes the current IPI interrupt assignment from the fix number of 4 to the number of CPUs defined in the system. Signed-off-by: Tim Anderson <tanderson@mvista.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* MIPS: Build fix - include <linux/smp.h> into all smp_processor_id() users.Ralf Baechle2009-06-241-0/+1
| | | | | | | | | Some of the were relying into smp.h being dragged in by another header which of course is fragile. <asm/cpu-info.h> uses smp_processor_id() only in macros and including smp.h there leads to an include loop, so don't change cpu-info.h.

* irq: change ->set_affinity() to return statusYinghai Lu2009-04-281-1/+3
| | | | | | | | | | | | | | | | | | | according to Ingo, change set_affinity() in irq_chip should return int, because that way we can handle failure cases in a much cleaner way, in the genirq layer. v2: fix two typos [ Impact: extend API ] Signed-off-by: Yinghai Lu <yinghai@kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Suresh Siddha <suresh.b.siddha@intel.com> Cc: "Eric W.

* MIPS: Malta: make a needlessly global integer variable staticDmitri Vorobiev2009-03-301-1/+1
| | | | | | | | | | The variable `mips_revision_corid' is needlessly defined global in arch/mips/mti-malta/malta-init.c, and this patch makes it static. Build-tested with malta_defconfig. Signed-off-by: Dmitri Vorobiev <dmitri.vorobiev@movial.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* irq: update all arches for new irq_descMike Travis2009-01-121-2/+3
| | | | | | | | | Impact: cleanup, update to new cpumask API Irq_desc.affinity and irq_desc.pending_mask are now cpumask_var_t's so access to them should be using the new cpumask API. Signed-off-by: Mike Travis <travis@sgi.com>
* cpumask: make irq_set_affinity() take a const struct cpumaskRusty Russell2008-12-131-3/+3
| | | | | | | | | | | | | | | | | | | | | | | Impact: change existing irq_chip API Not much point with gentle transition here: the struct irq_chip's setaffinity method signature needs to change. Fortunately, not widely used code, but hits a few architectures. Note: In irq_select_affinity() I save a temporary in by mangling irq_desc[irq].affinity directly. Ingo, does this break anything?

* MIPS: Malta: Consolidate platform device code.Ralf Baechle2008-12-043-69/+50
| | | | | After adding the RTC platform device to malta-platform.c malta-mtd.c should get unified with the rest of the platform device code.
* MIPS: Malta: Add back RTC supportTiejun Chen2008-12-041-9/+47
| | | | | | | | | | | With the conversion of MIPS to RTC_LIB the old RTC driver CONFIG_RTC became unselectable. Fix by setting up a platform device. Also enable RTC_CLASS so system time gets set from RTC on kernel initialization.
