* powerpc: Make syscall tracing use tracehook.h helpersRoland McGrath2008-07-28
| | | | | | | | | | | | This changes powerpc syscall tracing to use the new tracehook.h entry points. There is no change, only cleanup. In addition, the assembly changes allow do_syscall_trace_enter() to abort the syscall without losing the information about the original r0 value.

* powerpc: Call tracehook_signal_handler() when setting up signal framesRoland McGrath2008-07-28
| | | | | | | | | | | | | This makes the powerpc signal handling code call tracehook_signal_handler() after a handler is set up. This means that using PTRACE_SINGLESTEP to enter a signal handler will report to ptrace on the first instruction of the handler, instead of the second. This is consistent with what x86 and other machines do, and what users and debuggers want. BenH: Fixed up the test for the trap value.

* powerpc: Update cpu_sibling_maps dynamicallyNathan Lynch2008-07-28
| | | | | | | | | | | | | Rather doing one initialization pass over all the per-cpu cpu_sibling_maps at boot, update the maps at cpu online/offline time. This is a behavior change -- the thread_siblings attribute now reflects only online siblings, whereas it would display offline siblings before. The new behavior matches that of x86, and is arguably more useful. Signed-off-by: Nathan Lynch <ntl@pobox.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

| | | | | | | | | | | | This piece of code is broken for >2 threads, and possibly in some other subtle ways (such as comparing a value obtained from an "ibm,ppc-interrupt-server#s" property to a value obtained from a "reg" property) and doesn't seem to have any useful purpose in the first place other than a dubious warning in case NR_CPUS is too small, which probably isn't the right place to do so.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Minor cleanups for the MMC/SD support on avr32: - Make at32_add_device_mci() properly initialize "missing" platform data ... so boards like STK1002 won't try GPIO 0. - Switch over to gpio_is_valid() instead of testing for only one designated value. - Provide STK1002 platform data for the unlikely case that switches are set so first Ethernet controller isn't in use. (That's the only way to get card detect and writeprotect switch sensing on the STK1000.) And get rid of one "unused variable" warning.

| * | avr32: allow system timer to share interrupt to make OProfile workVoss, Nikolaus2008-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following patch allows the avr32_comparator interrupt to be shared. This is necessary as the avr32 oprofile driver shares the irq group 0 with the timer. To make OProfile actually work on AVR32, a small patch for oprofiled is also needed (posted to the oprofile mailing list).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does a few small cleanups around the atmel mci platform code and in the atmel-mci driver. The platform changes simply removes an unused variable, uses the fact that by the end we always have some form of platform data and notes that GPIO_PIN_NONE != 0. This last point could cause the incorrect attempt to twice reserve pin PA0. While we've got the hood up, add linux/err.h to the atmel-mci.c include list. It needs it and generally pulls it by voodoo but I did once stumble across a config which don't build. This is against Linus' latest git.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current interrupt handling on s390 misbehaves on an error case. On s390 each cpu has the prefix area (lowcore) for interrupt delivery. This memory must always be available. If we fail to access the prefix area for a guest on interrupt delivery the configuration is completely unusable. There is no point in sending another program interrupt to an inaccessible lowcore. Furthermore, we should not bug the host kernel, because this can be triggered by userspace. I think the guest kernel itself can not trigger the problem, as SET PREFIX and SIGNAL PROCESSOR SET PREFIX both check that the memory is available and sane. As this is a userspace bug (e.g. setting the wrong guest offset, unmapping guest memory) we should kill the userspace process instead of BUGing the host kernel. In the long term we probably should notify the userspace process about this problem. Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Avi Kivity <avi@qumranet.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an event (such as an interrupt) is injected, and the stack is shadowed (and therefore write protected), the guest will exit. The current code will see that the stack is shadowed and emulate a few instructions, each time postponing the injection. Eventually the injection may succeed, but at that time the guest may be unwilling to accept the interrupt (for example, the TPR may have changed). This occurs every once in a while during a Windows 2008 boot. Fix by unshadowing the fault address if the fault was due to an event injection. Signed-off-by: Avi Kivity <avi@qumranet.com>
