2007-06-08sh: Support for multiple nodes.Paul Mundt3-0/+104
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 <[email protected]>
2007-06-08sh: Use asm/sections.h for linker section symbols.Paul Mundt1-7/+4
Kill off a bunch of externs, and use sections.h instead.. Signed-off-by: Paul Mundt <[email protected]>
2007-06-08sh: Fix up max_zone_pfns[] with multiple nodes.Paul Mundt1-12/+17
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 <[email protected]>
2007-06-08sh: Wire up mempolicy syscalls.Paul Mundt1-3/+3
Wire up mbind and get/set_mempolicy() in their reserved places. Signed-off-by: Paul Mundt <[email protected]>
2007-06-08sh: Tidy compiler warnings for SH-2A build.Paul Mundt2-1/+1
Signed-off-by: Paul Mundt <[email protected]>
2007-06-08sh: Wrap CPU tuning through cc-option.Paul Mundt1-5/+7
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 <[email protected]>
2007-06-08sh: Enable IPR-IRQ for SH7206.Paul Mundt1-0/+1
Signed-off-by: Paul Mundt <[email protected]>
2007-06-08sh: Mark sparsemem regions present earlier.Paul Mundt1-4/+5
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 <[email protected]>
2007-06-08sh: Register multiple nodes in topology_init().Paul Mundt1-0/+7
If we have multiple nodes, register these at topology_init() time. Signed-off-by: Paul Mundt <[email protected]>
2007-06-08sh: Allow for bootmem debug support.Paul Mundt1-0/+4
Handy for debugging bootmem troubles. Signed-off-by: Paul Mundt <[email protected]>
2007-06-08sh: sparsemem support.Paul Mundt3-25/+22
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 <[email protected]>
2007-06-08sh: Add L-BOX RE2 to mach-types.Nobuhiro Iwamatsu1-0/+1
Signed-off-by: Nobuhiro Iwamatsu <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2007-06-08sh: Align .machvec.init section on a 4-byte boundary.Takashi YOSHII1-0/+1
.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 <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2007-06-08sh: Fix SH-4 CPU selects.Paul Mundt3-7/+7
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 <[email protected]>
2007-06-08sh: Rip out special unknown machvec.Paul Mundt7-48/+13
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 <[email protected]>
2007-06-08sh: Kill off machvec aliases.Paul Mundt30-71/+66
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 <[email protected]>
2007-06-08sh: Get multiple boards in one image working again.Paul Mundt1-38/+50
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 <[email protected]>
2007-06-08sh: Fixup cmdline handling from machvec changes.Paul Mundt1-6/+7
The command line wasn't being saved off properly after the machvec changes went in, fix it up. Signed-off-by: Paul Mundt <[email protected]>
2007-06-08sh: Rework CPU/board dependencies.Paul Mundt3-158/+165
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 <[email protected]>
2007-06-08sh: Shut up SH2-DSP compile warnings.Paul Mundt2-2/+2
Signed-off-by: Paul Mundt <[email protected]>
2007-06-08sh: Fixup machvec support.Paul Mundt4-150/+122
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 <[email protected]>
2007-06-08sh: __user annotations for __get/__put_user().Paul Mundt4-14/+12
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 <[email protected]>
2007-06-08sh: Split out CPU topology initialization.Paul Mundt3-19/+26
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 <[email protected]>
2007-06-04sh: Fix se73180 platform device registration.Paul Mundt1-2/+2
Copy and paste error from se7343, fix it up. Signed-off-by: Paul Mundt <[email protected]>
2007-06-04sh: ioremap() through PMB needs asm/mmu.h.Paul Mundt1-0/+1
Signed-off-by: Paul Mundt <[email protected]>
2007-06-04sh: voyagergx: Fix build warnings.Paul Mundt1-6/+7
pr_debug() was using a %x on an unsigned long, which was making the build a bit noisy. Signed-off-by: Paul Mundt <[email protected]>
2007-06-04sh: Fix SH4-202 clock fwk set_rate() mismatch.Paul Mundt1-1/+1
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 <[email protected]>
2007-06-04sh: microdev: Fix compile warnings.Paul Mundt1-0/+1
irq.c needs linux/interrupt.h. Signed-off-by: Paul Mundt <[email protected]>
2007-06-04sh: Fix in_nmi symbol build error.Paul Mundt1-0/+2
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 <[email protected]>
2007-05-31sh: support older gcc'sAndrew Morton1-1/+1
Make my version of gcc happy. Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2007-05-31sh: trivial build cleanups.Evgeniy Polyakov3-0/+9
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 <[email protected]> Signed-off-by: Paul Mundt <[email protected]>

2007-05-21sh: Wire up kdump crash kernel exec in die().Paul Mundt1-0/+11
Now that we have the basic kdump support in place, add it in to die() so we can enter the crash kernel automatically. Signed-off-by: Paul Mundt <[email protected]>
2007-05-21sh: sr.bl toggling around idle sleep.Paul Mundt1-6/+27
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 <[email protected]>
2007-05-21sh: Disable psw support for R7785RP.Paul Mundt1-1/+4
While R7780RP and R7780MP support this, R7785RP does not. Signed-off-by: Paul Mundt <[email protected]>
2007-05-21sh: Fix page size alignment in __copy_user_page().Paul Mundt1-0/+1

2007-05-21sh: Fix up various compile warnings for SE boards.Paul Mundt3-2/+6
- setup-sh7750.c only defines the sh7751_ipr_map when building with SH7751 support. - 7722 Solution Engine was missing a mach-type entry, causing the macro in cf-enabler to be undefined. - arch/sh/mm/init.c needs linux/pagemap.h. Signed-off-by: Paul Mundt <[email protected]>

2007-05-21sh: revert addition of page fault notifiersChristoph Hellwig1-37/+0
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.

2007-05-14sh: Kill off pmb slab cache destructor.Paul Mundt1-41/+38
This is the last remaining slab destructor in the kernel, which we kill off and move the resultant list tracking logic up to the pmb_alloc()/pmb_free() paths. As Christoph Lameter pointed out, it's potentially unsafe to be taking the list lock in the destructor anyways, so this is also more fundamentally correct. With this in place, we're all set for killing off slab destructors from the kernel entirely. Signed-off-by: Paul Mundt <[email protected]>
2007-05-14sh: Fix up psw build rules for r7780rp.Paul Mundt1-1/+1
When reordering the Makefile rules, the psw support was being clobbered. Fix it up so it's linked in again. Signed-off-by: Paul Mundt <[email protected]>
