* NTFS: - Split ntfs_map_runlist() into ntfs_map_runlist() and a non-lockingAnton Altaparmakov2005-05-056-113/+119
| | | | | | | | | | | | | helper ntfs_map_runlist_nolock() which is used by ntfs_map_runlist(). This allows us to map runlist fragments with the runlist lock already held without having to drop and reacquire it around the call. Adapt all callers. - Change ntfs_find_vcn() to ntfs_find_vcn_nolock() which takes a locked runlist. This allows us to find runlist elements with the runlist lock already held without having to drop and reacquire it around the call. Adapt all callers.

| | * [IA64] perfmon & PAL_HALT againStephane Eranian2005-05-032-3/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pmu_active test is based on the values of PSR.up. THIS IS THE PROBLEM as it does not take into account the lazy restore logic which is as follow (simplified): context switch out: save PMDs clear psr.up release ownership context switch in: if (ctx->last_cpu == smp_processor_id() && ctx->cpu_activation == cpu_activation) { set psr.up return } restore PMD restore PMC ctx->last_cpu = smp_processor_id(); ctx->activation = ++cpu_activation; set psr.up The key here is that on context switch out, we clear psr.up and on context switch in we check if nobody else used the PMU on that processor since last time we came. In that case, we assume the PMD/PMC are ours and we simply reactivate. The Caliper problem is that between the moment we context switch out and the moment we come back, nobody effectively used the PMU BUT the processor went idle. Normally this would have no incidence but PAL_HALT does alter the PMU registers. In default_idle(), the test on psr.up is not strong enough to cover this case and we go into PAL which trashed the PMU resgisters. When we come back we falsely assume that this is our state yet it is corrupted. Very nasty indeed. To avoid the problem it is necessary to forbid going to PAL_HALT as soon as perfmon installs some valid state in the PMU registers. This happens with an application attaches a context to a thread or CPU. It is not enough to check the psr/dcr bits. Hence I propose the attached patch. It adds a callback in process.c to modify the condition to enter PAL on idle. Basically, now it is conditional to pal_halt=1 AND perfmon saying it is okay.

| | * [patch] MCA recovery module undefined symbol fixRuss Anderson2005-05-031-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch "MCA recovery improvements" added do_exit to mca_drv.c. That's fine when the mca recovery code is built in the kernel (CONFIG_IA64_MCA_RECOVERY=y) but breaks building the mca recovery code as a module (CONFIG_IA64_MCA_RECOVERY=m). Most users are currently building this as a module, as loading and unloading the module provides a very convenient way to turn on/off error recovery. This patch exports do_exit, so mca_drv.c can build as a module. Signed-off-by: Russ Anderson (rja@sgi.com) Signed-off-by: Tony Luck <tony.luck@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Jack Steiner uncovered some opportunities for improvement in the MCA recovery code. 1) Set bsp to save registers on the kernel stack. 2) Disable interrupts while in the MCA recovery code. 3) Change the way the user process is killed, to avoid a panic in schedule.

| | * [IA64] fix ia64 syscall auditingDavid Woodhouse2005-05-032-2/+5

The patch enables auditing of system calls set up via fsys_bubble_down, as well as ensuring that audit_syscall_exit() is called on return from sigreturn. Neglecting to check for TIF_SYSCALL_AUDIT at these points results in incorrect information in audit_context, causing frequent system panics when system call auditing is enabled on an ia64 system. I have tested this patch and have seen no problems with it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Andi noted that during normal runtime cpu_idle_map is bounced around a lot, and occassionally at a higher frequency than the timer interrupt wakeup which we normally exit pm_idle from. So switch to a percpu variable. I didn't move things to the slow path because it would involve adding scheduler code to wakeup the idle thread on the cpus we're waiting for.
