2007-07-26sh: remove support for sh7300 and solution engine 7300Magnus Damm
This patch removes old dead code: - kill off sh7300 cpu support - get rid of broken solution engine 7300 board support Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-07-26sh: Kill off virt_to_bus()/bus_to_virt().Paul Mundt
Wire up ARCH_NO_VIRT_TO_BUS, and kill off the remaining users. The dma-mapping code really wanted virt_to_phys()/phys_to_virt() anyways, there are no inherently special bus addresses. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-07-26sh: Restrict DSP support to specific CPUs.Paul Mundt
Not all CPUs support the DSP, and this leads to problems when mixing and matching CPU types and DSP opcodes. Fix this up by only allowing CONFIG_SH_DSP to be enabled for the CPUs that explicitly have such a block. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2007-07-25sh: remove old broken pint codeMagnus Damm
The code in arch/sh/kernel/cpu/irq/pint.c doesn't compile, so let's get rid of it to make space for a future pint implementation on top of intc. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-07-25sh: Reclaim beginning of P3 space for vmalloc area.Paul Mundt
The first 1MB of P3 space was reserved and used for page colouring, as we've reworked that to use fixmaps, we can reclaim the space and hand it back to VMALLOC_START. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-07-24sh: Fix Dreamcast DMA issues.Adrian McMenamin
The current SH DMA API is somewhat broken, not correctly matching virtual channel to the correct SH DMAC. This wasn't noticeable when using g2 DMA for the sound driver - one channel 0 is as good as any other! - but caused the pvr2 driver to fail. This patch fixes the pvr2 problem and consequently fixes the sound driver to ensure it continues to function.

2007-07-24sh: Add kmap_coherent()/kunmap_coherent() interface for SH-4.Paul Mundt
This wires up kmap_coherent() and kunmap_coherent() on SH-4, and moves away from the p3map_mutex and reserved P3 space, opting to use fixmaps for colouring instead. The copy_user_page()/clear_user_page() implementations are moved to this, which fixes the nasty blowups with spinlock debugging as a result of having some of these calls nested under the page table lock.

2007-07-22x86: Replace NSC/Cyrix specific chipset access macros by inlined functions.Juergen Beisert
Due to index register access ordering problems, when using macros a line like this fails (and does nothing): setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88); With inlined functions this line will work as expected. Note about a side effect: Seems on Geode GX1 based systems the "suspend on halt power saving feature" was never enabled due to this wrong macro expansion. With inlined functions it will be enabled, but this will stop the TSC when the CPU runs into a HLT instruction. Kernel output something like this: Clocksource tsc unstable (delta = -472746897 ns) This is the 3rd version of this patch. - Adding missed arch/i386/kernel/cpu/mtrr/state.c Thanks to Andres Salomon - Adding some big fat comments into the new header file Suggested by Andi Kleen AK: fixed x86-64 compilation Signed-off-by: Juergen Beisert <juergen@kreuzholzen.de> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-07-22x86: Fix alternatives and kprobes to remap write-protected kernel textAndi Kleen
Reenable kprobes and alternative patching when the kernel text is write protected by DEBUG_RODATA Add a general utility function to change write protected text. The new function remaps the code using vmap to write it and takes care of CPU synchronization. It also does CLFLUSH to make icache recovery faster. There are some limitations on when the function can be used, see the comment. This is a newer version that also changes the paravirt_ops code. text_poke also supports multi byte patching now. Contains bug fixes from Zach Amsden and suggestions from Mathieu Desnoyers.

2007-07-22x86: i386-show-unhandled-signals-v3Masoud Asgharifard Sharbiani
This patch makes the i386 behave the same way that x86_64 does when a segfault happens. A line gets printed to the kernel log so that tools that need to check for failures can behave more uniformly between debug.show_unhandled_signals sysctl variable to 0 (or by doing echo 0 > /proc/sys/debug/exception-trace) Also, all of the lines being printed are now using printk_ratelimit() to deny the ability of DoS from a local user with a program like the following: main() { while (1) if (!fork()) *(int *)0 = 0; } This new revision also includes the fix that Andrew did which got rid of new sysctl that was added to the system in earlier versions of this. Also, 'show-unhandled-signals' sysctl has been renamed back to the old 'exception-trace' to avoid breakage of people's scripts. AK: Enabling by default for i386 will be likely controversal, but let's see what happens AK: Really folks, before complaining just fix your segfaults AK: I bet this will find a lot of silent issues Signed-off-by: Masoud Sharbiani <masouds@google.com> Signed-off-by: Andi Kleen <ak@suse.de> [ Personally, I've found the complaints useful on x86-64, so I'm all for this.

2007-07-22[POWERPC] MPIC protected sourcesBenjamin Herrenschmidt
Some HW platforms, such as the new cell blades, requires some MPIC sources to be left alone by the operating system. This implements support for a "protected-sources" property in the mpic controller node containing a list of source numbers to be protected against operating system interference. For those interested in the gory details, the MPIC on the southbridge of those blades has some of the processor outputs routed to the cell, and at least one routed as a GPIO to the service processor. It will be used in the GA product for routing some of the southbridge error interrupts to the service processor which implements some of the RAS stuff, such as checkstopping when fatal errors occurs before they can propagate.

2007-07-22[POWERPC] Allow smp_call_function_single() to current cpuAvi Kivity
This removes the requirement for callers to get_cpu() to check in simple cases. i386 and x86_64 already received a similar treatment. Signed-off-by: Avi Kivity <avi@qumranet.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
