2007-06-08sh: Fix up cpu to node mapping in sysfs.Paul Mundt
Currently cpu_to_node() is always 0 in the UP case, though we do want to have the CPU association linked in under sysfs even in the cases where we're only on a single CPU. Fix this up, so we have the cpu0 link on all of the available nodes that don't already have a CPU link of their own. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Fix the SH7722 flatmem build.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Make NUMA depend on sparsemem.Paul Mundt
The only platforms that are supporting NUMA are doing so via sparsemem, so update the dependency. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: URAM node support for SH7722.Paul Mundt
This adds the URAM block on SH7722 as a separate node. Sparsemem is required for this, or it can simply be disabled by explicitly selecting a flatmem model. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Support for multiple nodes.Paul Mundt
This adds basic support for multiple nodes on SH machines. This is primarily useful for boards with many different memory blocks that are otherwise unused (SH7722/SH7785 URAM and so forth). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Use asm/sections.h for linker section symbols.Paul Mundt
Kill off a bunch of externs, and use sections.h instead.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Fix up max_zone_pfns[] with multiple nodes.Paul Mundt
Currently using multiple nodes tramples the ZONE_NORMAL max low pfn, tidy up the logic a bit to get it all working as expected. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Wire up mempolicy syscalls.Paul Mundt
Wire up mbind and get/set_mempolicy() in their reserved places. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Tidy compiler warnings for SH-2A build.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Wrap CPU tuning through cc-option.Paul Mundt
Some compilers don't support the explicit CPU tuning, while binutils is still able to handle the special subtype-specific opcodes. Make the CFLAG optional, falling back on the compiler default if nothing better exists. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Enable IPR-IRQ for SH7206.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Mark sparsemem regions present earlier.Paul Mundt
We have to call in to sparse_memory_present_with_active_regions() earlier in order for sparsemem to be happy. This was being called too late, and was causing troubles with the platforms that needed to enable sparsemem. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Register multiple nodes in topology_init().Paul Mundt
If we have multiple nodes, register these at topology_init() time. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Allow for bootmem debug support.Paul Mundt
Handy for debugging bootmem troubles. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: sparsemem support.Paul Mundt
This implements basic sparsemem support for SH. Presently this only uses static sparsemem, and we still permit explicit selection of flatmem. Those boards that want sparsemem can select it as usual. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Add L-BOX RE2 to mach-types.Nobuhiro Iwamatsu
Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Align .machvec.init section on a 4-byte boundary.Takashi YOSHII
.machvec.init can be misaligned with the recent machvec changes, forcibly align it on the boundary that it expects, as before. Signed-off-by: Takashi YOSHII <takashi.yoshii.ze@hitachi.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Fix SH-4 CPU selects.Paul Mundt
Now that select no longer works for selecting the "closest" CPU, we have to explicitly reference the precise sub-type in the few places where it actually matters (presently only setup code and some legacy sh-sci cruft). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Rip out special unknown machvec.Paul Mundt
This kills off the BareCPU board as a "special" machvec, rather, we leave this as a default for when no other vector is available, or when we want to use it in combination with other vectors for testing with generic ops. As sh_mv is copied out anyways (or overloaded when an alternate vector is explicitly selected), this doesn't consume any additional memory. The generic machvec can be forcibly selected with sh_mv=generic, or by not having any other boards enabled. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Kill off machvec aliases.Paul Mundt
We now throw all of the machvecs in to .machvec.init and either select one on the command line, or copy out the first (and usually only) one to sh_mv. The rest are freed as usual. This gets rid of all of the silly sh_mv aliasing and makes the selection explicit rather than link-order dependent. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Get multiple boards in one image working again.Paul Mundt
This tidies up the build rules and permits multiple boards to be linked in to the same kernel. The earlier Kconfig work ensures that the CPU configuration is consistent across the boards, as this is the only thing that we can't do dynamically. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Fixup cmdline handling from machvec changes.Paul Mundt
The command line wasn't being saved off properly after the machvec changes went in, fix it up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Rework CPU/board dependencies.Paul Mundt
This was a big mess, rework the logic a bit so that we constrain to a particular subtype and figure out the board support based on that. This makes building subtype specific kernels supporting multiple boards possible again. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Shut up SH2-DSP compile warnings.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Fixup machvec support.Paul Mundt
This fixes up much of the machvec handling, allowing for it to be overloaded on boot. Making practical use of this still requires some Kconfig munging, however. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: __user annotations for __get/__put_user().Paul Mundt
This adds in some more __user annotations. These weren't being handled properly in some of the __get_user and __put_user paths, so tidy those up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-08sh: Split out CPU topology initialization.Paul Mundt
Split out the CPU topology initialization to a separate file, and switch it to a percpu type, rather than an NR_CPUS array. At the same time, switch to only registering present CPUs, rather than using the possible CPU map. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-04sh: Fix se73180 platform device registration.Paul Mundt
Copy and paste error from se7343, fix it up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-04sh: ioremap() through PMB needs asm/mmu.h.Paul Mundt
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-04sh: voyagergx: Fix build warnings.Paul Mundt
pr_debug() was using a %x on an unsigned long, which was making the build a bit noisy. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-04sh: Fix SH4-202 clock fwk set_rate() mismatch.Paul Mundt
With the SH7722 changes, ->set_rate() also takes an algo_id, SH4-202 was overlooked when this change went in. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

irq.c needs linux/interrupt.h. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-04sh: Fix in_nmi symbol build error.Paul Mundt
If CONFIG_KGDB_NMI is disabled, we're left with a stray in_nmi reference that can't be resolved. Move the symbol under the ifdef, too. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-05-31sh: trivial build cleanups.Evgeniy Polyakov
Several errors were spotted during building for custom config (SMP included). Although SMP still does not compile (no ipi and __smp_call_function) and does not work, this looks a bit cleaner. Some other errors obtained via gcc-4.1.0 build. Signed-off-by: Evgeniy Polyakov <johnpol@2ka.mipt.ru> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-05-21sh: sr.bl toggling around idle sleep.Paul Mundt
As pointed out by Saito-san, without the sr.bl manipulation we can occasionally hit delays in the idle loop due to interrupt handling, so ensure that interrupts are blocked before going to sleep. At the same time, we throw in TIF_POLLING_NRFLAG for the !hlt_counter case (primarily used by the ST-40 parts). Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-05-21sh: revert addition of page fault notifiersChristoph Hellwig
Just at the time you added them on sh we're removing them from other architectures. As there's no user yet this patch just removes them completely. Once you actually have a kprobes patch it should follow the direct call to kprobes_fault_handler model that powerpc, s390 and sparc64 employ in 2.6.22-rc1 and that I'm updating other architectures to.
