2007-02-13sh: heartbeat consolidation for banked LEDs.Paul Mundt
This consolidates the various board heartbeat LED implementations, used for strobing the load average across a LED bank. Those boards not implementing a full bank can hook in via the LED class. We leave the compat hook in the machvec for now until those non-banked boards are able to migrate to the drivers/leds. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-02-13sh: Switch to local TLB flush variants in additional callsites.Paul Mundt
Convert some of the global flush users over to using the local variants that don't need to use the global routines. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-13sh: Local TLB flushing variants for SMP prep.Paul Mundt
Rename the existing flush routines to local_ variants for use by the IPI-backed global flush routines on SMP. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-13sh: Fixup cpu_data references for the non-boot CPUs.Paul Mundt
There are a lot of bogus cpu_data-> references that only end up working for the boot CPU, convert these to current_cpu_data to fixup SMP. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-13sh: Use a per-cpu ASID cache.Paul Mundt
Previously this was implemented using a global cache, cache this per-CPU instead and bump up the number of context IDs to match NR_CPUS. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-13sh: add SH_CLK_MD Kconfig default.Andrew Morton
This option needs a default - otherwise `make allmodconfig' gets stuck in an infinite loop. Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-02-13sh: SH-DMAC compile fixesManuel Lauss
This patch does the following: - remove the make_ipr_irq stuff from dma-sh.c and replace it with a simple channel<->irq mapping table. - add DMTEx_IRQ constants for sh4 cpus - fix sh7751 DMAE irq number The SH7780 uses the same IRQs for DMA as other SH4 types, so I put the constants on top of the dma.h file. Other CPU types need to #define their own DMTEx_IRQ contants in their appropriate header. Signed-off-by: Manuel Lauss <mano@roarinelk.homelinux.net> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-13sh: add SH7760 IPR IRQ dataManuel Lauss

2007-02-13sh: Fix handle_BUG() compile error.Nobuhiro Iwamatsu
handle_BUG() uses TRAPA_BUG_OPCODE which is only defined for CONFIG_BUG, make sure it's not built when CONFIG_BUG=n. Signed-off-by: Nobuhiro Iwamatsu <hemamu@t-base.ne.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-13sh: Don't set reserved _PAGE_WT bit on SH-3.Paul Mundt
Only SH-4 needs to set _PAGE_WT when using write-through caching, don't attempt to set it on SH-3 where it ends up being a reserved bit. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-13sh: Lazy dcache writeback optimizations.Paul Mundt
This converts the lazy dcache handling to the model described in Documentation/cachetlb.txt and drops the ptep_get_and_clear() hacks used for the aliasing dcaches on SH-4 and SH7705 in 32kB mode. As a bonus, this slightly cuts down on the cache flushing frequency. With that and the PTEA handling out of the way, the update_mmu_cache() implementations can be consolidated, and we no longer have to worry about which configuration the cache is in for the SH7705 case. And finally, explicitly disable the lazy writeback on SMP (SH-4A). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-13sh: More tidying for large base pages.Paul Mundt
There were a few more things that needed fixing up, namely THREAD_SIZE and the TLB miss handler where certain PTRS_PER_PGD == PTRS_PER_PTE assumptions were being made. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-02-13sh: Fixup R7780RP iVDR clock enable.Paul Mundt
The iVDR clock enable bit happens to actually reside in a rather different place than what is documented, so fix it up accordingly. This fixes up SATA boot for some of the R7780RP boards that didn't default-enable the clock in the loader. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-13sh: allow earlyprintk baud rate to be set via command lineJamie Lenehan
This allows the baud rate for earlyprintk for sh4 without the standard BIOS to be set via the command line. This uses the same format as i386 and x86_64, which is: earlyprintk=serial,ttySC1,38400 The second parameter (ttySC1 above) is usually the console device name or the io address of the serial port. I allow that to be specified but ignore it in order to keep the format the same as i386/x86_64. Signed-off-by: Jamie Lenehan <lenehan@twibble.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-02-13sh: Use proper SH-2A CFLAGS on newer compilers.Paul Mundt
-m2 doesn't end up working particularly well when we've got a constrained toolchain target. Switch to the same semantics used by SH-4A to attempt to get it right. Spotted by Alex Song <songqf9@yahoo.ca>. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-13sh: Use a jump call table for debug trap handlers.Paul Mundt
This rips out most of the needlessly complicated sh_bios and kgdb trap handling, and forces it all through a common fast dispatch path. As more debug traps are inserted, it's important to keep them in sync for all of the parts, not just SH-3/4. As the SH-2 parts are unable to do traps in the >= 0x40 range, we restrict the debug traps to the 0x30-0x3f range on all parts, and also bump the kgdb breakpoint trap down in to this range (from 0xff to 0x3c) so it's possible to use for nommu. Optionally, this table can be padded out to catch spurious traps for SH-3/4, but we don't do that yet.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-12[PATCH] mark struct file_operations const 2Arjan van de Ven
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2007-02-11[PATCH] disable init/initramfs.c: architecturesJean-Paul Saman
Update all arch/*/kernel/vmlinux.lds.S to not include space for initramfs when CONFIG_BLK_DEV_INITRAMFS is not selected.

2006-12-12sh: Fixup kernel_execve() for syscall cleanups.Paul Mundt
SH-2 and SH-2A need to use a different syscall base for the trapa vector than the other parts, so fixup the logic in the kernel_execve() case. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-12sh: Fix get_wchan().Paul Mundt
Some time ago the schedule frame size changed and we failed to reflect this in get_wchan() at the time. This first popped up as a problem on SH7751R where schedule_frame ended up being unaligned and generating an unaligned trap. This fixes it up again.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-12sh: BUG() handling through trapa vector.Paul Mundt
Previously we haven't been doing anything with verbose BUG() reporting, and we've been relying on the oops path for handling BUG()'s, which is rather sub-optimal. This switches BUG handling to use a fixed trapa vector (#0x3e) where we construct a small bug frame post trapa instruction to get the context right. This also makes it trivial to wire up a DIE_BUG for the atomic die chain, which we couldn't really do before. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
