* cpumask: x86: Introduce cpumask_of_{node,pcibus} to replace ↵Rusty Russell2008-12-26
| | | | | | | | | | | | | | | {node,pcibus}_to_cpumask Impact: New APIs The old node_to_cpumask/node_to_pcibus returned a cpumask_t: these return a pointer to a struct cpumask. Part of removing cpumasks from the stack. Also makes __pcibus_to_node take a const pointer. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Acked-by: Ingo Molnar <mingo@elte.hu>
* cpumask: convert struct clock_event_device to cpumask pointers.Rusty Russell2008-12-13
| | | | | | | | | | | | | Impact: change calling convention of existing clock_event APIs struct clock_event_timer's cpumask field gets changed to take pointer, as does the ->broadcast function. Another single-patch change. For safety, we BUG_ON() in clockevents_register_device() if it's not set. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: Ingo Molnar <mingo@elte.hu>
* cpumask: make irq_set_affinity() take a const struct cpumaskRusty Russell2008-12-13
| | | | | | | | | | | | | | | | | | | | | | | Impact: change existing irq_chip API Not much point with gentle transition here: the struct irq_chip's setaffinity method signature needs to change. Fortunately, not widely used code, but hits a few architectures. Note: In irq_select_affinity() I save a temporary in by mangling irq_desc[irq].affinity directly. Ingo, does this break anything?

* cpumask: change cpumask_scnprintf, cpumask_parse_user, cpulist_parse, and ↵Rusty Russell2008-12-13
| | | | | | | | | | | | | | | | | | | | | | | cpulist_scnprintf to take pointers. Impact: change calling convention of existing cpumask APIs Most cpumask functions started with cpus_: these have been replaced by cpumask_ ones which take struct cpumask pointers as expected. These four functions don't have good replacement names; fortunately they're rarely used, so we just change them over.

* cpumask: centralize cpu_online_map and cpu_possible_mapRusty Russell2008-12-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: cleanup Each SMP arch defines these themselves. Move them to a central location. Twists: 1) Some archs (m32, parisc, s390) set possible_map to all 1, so we add a CONFIG_INIT_ALL_POSSIBLE for this rather than break them. 2) mips and sparc32 '#define cpu_possible_map phys_cpu_present_map'. Those archs simply have phys_cpu_present_map replaced everywhere. 3) Alpha defined cpu_possible_map to cpu_present_map; this is tricky so I just manipulate them both in sync. 4) IA64, cris and m32r have gratuitous 'extern cpumask_t cpu_possible_map' declarations.

* MN10300: Discard low-priority Tx interrupts when closing an on-chip serial portAkira Takeuchi2008-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Discard low-prioriy Tx interrupts when closing an MN10300 on-chip serial port. The MN10300 on-chip serial port uses three interrupts to manage its serial ports: (1) A very high priority interrupt that drives virtual DMA for Rx. (2) A very high priority interrupt that drives virtual DMA for Tx. (3) A normal priority virtual interrupt that does the normal UART interrupt stuff and is shared between Rx and Tx. mn10300_serial_stop_tx() only disables the high priority Tx interrupt. It doesn't also disable the normal priority one because it is shared with Rx. However, the high priority interrupt may interrupt local_irq_disabled() sections, and so may have queued up a low priority virtual interrupt whilst the UART driver is asking for the Tx interrupt to be disabled. The result of this can be an oops when we try to process the interrupt in mn10300_serial_transmit_interrupt() as port->uart.info and port->uart.info->tty may have gone away. To deal with this, if either of those pointers is NULL, we make sure the high-priority Tx interrupt is disabled and discard the interrupt. The low priority interrupt is disabled by the mn10300_serial_pic irq_chip table.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the introduction of the generic affinity autoselector, irq_select_affinity(), IRQs are now being retargetted, using a default mask, via the request_irq() path.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On ARMv6 and later CPUs, it is possible for userspace processes to get stuck on a misaligned load or store due to the "ignore fault" setting; unlike previous CPUs, retrying the instruction without the 'A' bit set does not always cause the load to succeed. We have no real option but to default to fixing up alignment faults on these CPUs, and having the CPU fix up those misaligned accesses which it can.

One of the things it does is to make READ_IMPLIES_EXEC be set in ->personality if we are running on a CPU that doesn't support the XN ("Execute Never") page table bit or if we are running a binary that needs an executable stack. This exposed a latent bug in ARM's asm/processor.h due to which we'll end up placing the stack at a very low address, where it will bump into the heap on any application that uses significant amount of stack or heap or both, causing many interesting crashes. Fix this by testing the ADDR_LIMIT_32BIT bit in ->personality instead of testing for equality against PER_LINUX_32BIT.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 0c65f459ce6c intended to fix truncation issues with fls() on ARMv5+ by renaming it to __fls() and wrapping it into a C function. However that didn't take into account the fact that __fls() already already had different semantics in the kernel. Let's move the __fls() code into fls() function directly, and redefine __fls() with the appropriate semantics. While at it, bring a generic __fls() definition for pre ARMv5 too.

The emulation code for the pdist instruction uses RS1(insn) for both source registers rs1 and rs2, which is obviously wrong and leads to the instruction doing nothing (the observed problem), and further inspection of the code shows that RS1 uses a shift of 24 and RD a shift of 25, which clearly cannot both be right; examining SPARC documentation indicates the correct shift for RS1 is 14. This patch fixes the bug if single-stepping over the affected instruction in the debugger, but not if the testcase is run standalone. For that, Wind River has another patch I hope they will send as a followup to this patch submission. Signed-off-by: Joseph Myers <joseph@codesourcery.com> Signed-off-by: David S.

However, looking at the user-space oprofile code there isn't the matching entry in libop/op_cpu_type.c or the events/unit_mask files in events/i386 directory. The Intel AP-485 says this is a "Intel Pentium M processor model D". Seems like the oprofile kernel driver should be identifying the processor as "i386/p6_mobile" The driver identification code doesn't look quite right in nmi_init.c http://git.kernel.org/?p=linux/kernel/git/sfr/linux-next.git;a=blob;f=arch/x86/oprofile/nmi_int.c;h=022cd41ea9b4106e5884277096e80e9088a7c7a9;hb=HEAD has: 409 case 10 ... 13: 410 *cpu_type = "i386/p6"; 411 break; Referring to the Intel AP-485: case 10 and 11 should produce "i386/piii" case 13 should produce "i386/p6_mobile" I didn't see anything for case 12. Something like the attached patch. I don't have a celeron machine to verify that changes in this area of the kernel fix thing. -Will Signed-off-by: William Cohen <wcohen@redhat.com> Tested-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Acked-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Robert Richter <robert.richter@amd.com>
