* [SPARC64]: Fix memory corruption in pci_4u_free_consistent().David S. Miller2006-10-26

* [SPARC64]: Fix central/FHC bus handling on Ex000 systems.David S. Miller2006-10-26
| | | | | | | | | | | | | | | | | | | | | 1) probe_other_fhcs() wants to see only non-central FHC busses, so skip FHCs that don't sit off the root 2) Like SBUS, FHC can lack the appropriate address and size cell count properties, so add an of_busses[] entry and handlers for that. 3) Central FHC irq translator probing was buggy. We were trying to use dp->child in irq_trans_init but that linkage is not setup at this point. So instead, pass in the parent of "dp" and look for the child "fhc" with parent "central". Thanks to the tireless assistence of Ben Collins in tracking down these problems and testing out these fixes. Signed-off-by: David S. Miller <davem@davemloft.net>

* [PATCH] AVR32: Use __raw MMIO access for internal peripheralsHaavard Skinnemoen2006-10-25
| | | | | | | | | | | | | | | The read[bwl] and write[bwl] functions are meant for accessing PCI devices. How this is achieved on AVR32 is unknown, as there are no systems with a PCI bridge available yet. On-chip peripheral access, however, should not depend on how we end up implementing PCI access, so using __raw_read[bwl]/__raw_write[bwl] is the right thing to do for on-chip peripherals. This patch converts the drivers for the static memory controller, interrupt controller, PIO controller and system manager to use __raw MMIO access.

| * [PATCH] x86-64: Only look at per_cpu data for online cpus.Eric W. Biederman2006-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When I generalized __assign_irq_vector I failed to pay attention to what happens when you access a per cpu data structure for a cpu that is not online. It is an undefined case making any code that does it have undefined behavior as well. The code still needs to be able to allocate a vector across cpus that are not online to properly handle combinations like lowest priority interrupt delivery and cpu_hotplug. Not that we can do that today but the infrastructure shouldn't prevent it. So this patch updates the places where we touch per cpu data to only touch online cpus, it makes cpu vector allocation an atomic operation with respect to cpu hotplug, and it updates the cpu start code to properly initialize vector_irq so we don't have inconsistencies.

| * [PATCH] x86-64: Simplify the vector allocator.Eric W. Biederman2006-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no reason to remember a per cpu position of which vector to try. Keeping a global position is simpler and more likely to result in a global vector allocation even if I don't need or require it. For level triggered interrupts this means we are less likely to acknowledge another cpus irq, and cause the level triggered irq to harmlessly refire. This simplification makes it easier to only access data structures of online cpus, by having fewer special cases to deal with. Signed-off-by: Eric W.

| * | [POWERPC] IPIC: Fix spinlock recursion in set_irq_handlerScott Wood2006-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This causes ipic_set_irq_type to set the handler directly rather than call set_irq_handler, which causes spinlock recursion because the lock is already held when ipic_set_irq_type is called. I'm also not convinced that ipic_set_irq_type should be changing the handler at all. There seem to be several controllers that don't and several that do. Those that do would break what appears to be a common usage of calling set_irq_chip_and_handler followed by set_irq_type, if a non-standard handler were to be used. OTOH, irq_create_of_mapping() doesn't set the handler, but only calls set_irq_type(). This patch gets things working in the spinlock-debugging-enabled case, but I'm curious as to where the handler setting is ideally supposed to be done. I don't see any documentation on set_irq_type() that clarifies what the semantics are supposed to be.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, spufs_mbox_read transfers more bytes than requested on a read. If you ask for four bytes, you get eight. This fixes it to transfer the largest multiple of four bytes that is less than or equal to the number you asked for. Note: one nasty property of this file in spufs is that you can only read multiples of four bytes in the first place, since there is no way to atomically put back a few bytes into the hardware register. Thus, reading less than four bytes returns -EINVAL. Asking for more than four returns the largest possible multiple of four.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Cell CPU timebase has an erratum. When reading the entire 64 bits of the timebase with one mftb instruction, there is a handful of cycles window during which one might read a value with the low order 32 bits already reset to 0x00000000 but the high order bits not yet incremeted by one. This fixes it by reading the timebase again until the low order 32 bits is no longer 0. That might introduce occasional latencies if hitting mftb just at the wrong time, but no more than 70ns on a cell blade, and that was considered acceptable.

| * | [POWERPC] Support feature fixups in vdso'sBenjamin Herrenschmidt2006-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reworks the feature fixup mecanism so vdso's can be fixed up. The main issue was that the construct: .long label (or .llong on 64 bits) will not work in the case of a shared library like the vdso. It will generate an empty placeholder in the fixup table along with a reloc, which is not something we can deal with in the vdso. The idea here (thanks Alan Modra !) is to instead use something like: 1: .long label - 1b That is, the feature fixup tables no longer contain addresses of bits of code to patch, but offsets of such code from the fixup table entry itself. That is properly resolved by ld when building the .so's. I've modified the fixup mecanism generically to use that method for the rest of the kernel as well. Another trick is that the 32 bits vDSO included in the 64 bits kernel need to have a table in the 64 bits format. However, gas does not support 32 bits code with a statement of the form: .llong label - 1b (Or even just .llong label) That is, it cannot emit the right fixup/relocation for the linker to use to assign a 32 bits address to an .llong field. Thus, in the specific case of the 32 bits vdso built as part of the 64 bits kernel, we are using a modified macro that generates: .long 0xffffffff .llong label - 1b Note that is assumes that the value is negative which is enforced by the .lds (those offsets are always negative as the .text is always before the fixup table and gas doesn't support emiting the reloc the other way around).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are currently two versions of the functions for applying the feature fixups, one for CPU features and one for firmware features. In addition, they are both in assembly and with separate implementations for 32 and 64 bits. identify_cpu() is also implemented in assembly and separately for 32 and 64 bits. This patch replaces them with a pair of C functions. The call sites are slightly moved on ppc64 as well to be called from C instead of from assembly, though it's a very small change, and thus shouldn't cause any problem.

We don't really have enough information to do that accurately, so don't try. Instead, we now calculate stolen time as time that the current cpu thread is not actually dispatching instructions. On chips without a PURR, we cannot do this, so stolen time will always be zero. On chips with a PURR, this is merely the difference between the elapsed PURR values and the elapsed TB values. This gives us much more sane vaules from tools such as mpstat, even if they are still a bit strange e.g. 2 busy threads on one cpu will both appear to have 50% user time and 50% stolen time while 1 busy thread on a cpu will look like 100% user on one of them and 100% idle on the other.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the INTC2 code contains a fixed IRQ table that it iterates through to set the handler type, we move this in to the CPU subtype setup code instead and allow for submitting the table that way. This drops the ST40 tables, as nothing has been happening with those processors, while converting the only existing users to use the new table directly (SH7760 and SH7780).

| * | sh: Fix exception_handling_table alignment.Paul Mundt2006-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the recent change ripping out interrupt_table, explicit padding of the table was missing, causing bad things to happen when manually inserting handlers in to the table. This problem particularly showed up in relation to do_fpu_state_restore() which was inserted quite deeply in to the table and ended up scribbling over a slab object.

| | | | | | | | | | | | | | | | | | | | | | | | Now with the ide.h mess sorted out, most of these boards don't need their own directory. Move the headers out, and update the driver paths. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | sh: Proper show_stack/show_trace() implementation.Paul Mundt2006-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This splits out some of the previous show_stack() implementation which was mostly doing the show_trace() work without actually dumping any of the stack contents. This now gets split in to two sections, where we do the fetching of the stack pointer and subsequent stack dumping in show_stack(), while moving the call trace in to show_trace().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a typo in the C3 latency test to decide of the TSC should be used or not. It used the C2 latency threshold, not the C3 one. Fix that. This should fix the time on various dual core laptops. Signed-off-by: Andi Kleen <ak@suse.de>
* | | | [MIPS] Fix aliasing bug in copy_to_user_page / copy_from_user_pageRalf Baechle2006-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current implementation uses a sequence of a cacheflush and a copy. This is racy in case of a multithreaded debuggee and renders GDB virtually unusable. Aside this fixes a performance hog rendering access to /proc/cmdline very slow and resulting in a enough cache stalls for the 34K AP/SP programming model to make the bare metal code on the non-Linux VPE miss RT deadlines. The main part of this patch was originally written by Ralf Baechle; Atushi Nemoto did the the debugging.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default route the 8254 over the 8259 and only disable it on ATI boards where this causes double timer interrupts. This should unbreak some Nvidia boards where the timer doesn't seem to tick of it isn't enabled in the 8259. At least one VIA board also seemed to have a little trouble with the disabled 8259. For 2.6.20 we'll try both dynamically without black listing, but I think for .19 this is the safer approach because it has been already well tested in earlier kernels. This also makes the x86-64 behaviour the same as i386. Command line options can change all this of course. Signed-off-by: Andi Kleen <ak@suse.de>
