sh: Fix bogus regs pointer in do_IRQ().

2007-03-14T04:03:35Z

SH-3 and SH-4 were trampling the register, and SH-2 wasn't even setting it in the first place. This ended up with some rather broken behaviour in the sysrq show_regs(). Signed-off-by: Paul Mundt

sh: Revert TLB miss fast-path changes that broke PTEA parts.

2007-02-14T05:13:10Z

This ended up causing problems for older parts (particularly ones using PTEA). Revert this for now, it can be added back in once it's had some more testing. Signed-off-by: Paul Mundt

sh: Fixup cpu_data references for the non-boot CPUs.

2007-02-13T01:54:45Z

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

sh: More tidying for large base pages.

2007-02-13T01:54:44Z

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

sh: shmin updates.

2007-02-13T01:54:44Z

This fixes up shmin (and SH7706/SH7708) IPR support for some of the recent API changes. Signed-off-by: Takashi YOSHII Signed-off-by: Paul Mundt

sh: Use a jump call table for debug trap handlers.

2007-02-13T01:54:43Z

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

sh: stacktrace/lockdep/irqflags tracing support.

2006-12-06T01:45:40Z

Wire up all of the essentials for lockdep.. Signed-off-by: Paul Mundt

sh: Clock framework tidying.

2006-12-06T01:45:40Z

This syncs up the SH clock framework with the linux/clk.h API, for which there were only some minor changes required, namely the clk_get() dev_id and subsequent callsites. Signed-off-by: Paul Mundt

sh: Fixup various PAGE_SIZE == 4096 assumptions.

2006-12-06T01:45:39Z

There were a number of places that made evil PAGE_SIZE == 4k assumptions that ended up breaking when trying to play with 8k and 64k page sizes, this fixes those up. The most significant change is the way we load THREAD_SIZE, previously this was done via: mov #(THREAD_SIZE >> 8), reg shll8 reg to avoid a memory access and allow the immediate load. With a 64k PAGE_SIZE, we're out of range for the immediate load size without resorting to special instructions available in later ISAs (movi20s and so on). The "workaround" for this is to bump up the shift to 10 and insert a shll2, which gives a bit more flexibility while still being much cheaper than a memory access. Signed-off-by: Paul Mundt

sh: TLB miss fast-path optimizations.

2006-12-06T01:45:38Z

Handle simple TLB miss faults which can be resolved completely from the page table in assembler. Signed-off-by: Stuart Menefy Signed-off-by: Paul Mundt
