* [PATCH] m68k: thread_info header cleanupAl Viro2005-11-13
| | | | | | | | | | | | | | | | | | | | a) in smp_lock.h #include of sched.h and spinlock.h moved under #ifdef CONFIG_LOCK_KERNEL. b) interrupt.h now explicitly pulls sched.h (not via smp_lock.h from hardirq.h as it used to) c) in three more places we need changes to compensate for (a) - one place in arch/sparc needs string.h now, hardirq.h needs forward declaration of task_struct and preempt.h needs direct include of thread_info.h. d) thread_info-related helpers in sched.h and thread_info.h put under ifndef __HAVE_THREAD_FUNCTIONS. Obviously safe.

* [PATCH] x86: fix cpu_khz with clock=pitTim Mann2005-11-13
| | | | | | | | | | | | | | | | | | Fix http://bugzilla.kernel.org/show_bug.cgi?id=5546 The cpu_khz global is not initialized and remains 0 if you boot with clock=pit, even if the processor does have a TSC. This may have bad ramifications since the variable is used in various places scattered around the kernel, though I didn't check them all to see if they can tolerate cpu_khz = 0. You can observe the problem by doing "cat /proc/cpuinfo"; the cpu MHz line says 0.000. The fix is trivial; call init_cpu_khz() from init_pit(), just as it's called from the timers/timer_foo.c:init_foo() for other values of foo.

We had similar problems with other ioctls where userspace did things like that. What we did there was to put the compat handler to generic code.

Since SN firmware does not pass enough ACPI information to identify VGA cards and the associated legacy IO/MEM addresses, we rely on the EFI PCDP table.

Tom,Steve: The implementation of get_tbfreq() I've done for 32 bits returns a long long (r3, r4) not a long. This is such that if we ever add support for >4Ghz timebases on ppc32, the userland interface won't have to change. I have tested gettimeofday() using some glibc patches in both ppc32 and ppc64 kernels using 32 bits userland (I haven't had a chance to test a 64 bits userland yet, but the implementation didn't change and was tested earlier).

The only change during the move is to standardise the protecting #ifdef/#define in udbg.h, and move its banner comment above the initial #ifdef (which seems to be normal practice).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After much testing and agony, I've discovered that my previous ohci1394 quirk for Toshiba laptops is not 100% reliable. It apparently fails to do the interrupt line change either correctly or in time, since in about 2 out of 5 boots, the kernel's irqdebug code will *still* disable irq 11 when the ohci1394 driver is loaded (at pci_enable_device time I think). This patch switches things around a little in the workaround. First, it removes the mdelay. I didn't see a need for it and my testing has shown that it's not necessary for the quirk to work. Secondly, instead of trying to change the interrupt line to what ACPI tells us it should be, this patch makes the quirk use the value in the PCI_INTERRUPT_LINE register. On this laptop at least, that seems to be the right thing to do, though additional testing on other laptops and/or with actual firewire devices would be appreciated.

Instead of walking the task_list of all processes, 2 bitmaps are used to efficently store and lookup state, inuse and needs flushing. The entire rid address space is now used before calling wrap_mmu_context and global tlb flushing. Special thanks to Ken and Rohit for their review and modifications in using a bit flushmap.

We need multiple notification points for these events because they can take many seconds to run which has nasty effects on the behaviour of the rest of the system. DIE_SS replaced by a generic DIE_FAULT which checks the vector number, to allow interception of faults other than SS. DIE_MACHINE_{HALT,RESTART} added to allow last minute close down processing, especially when the halt/restart routines are called from error handlers. DIE_OOPS added. The check for kprobe's break numbers has been moved from traps.c to kprobes.c, allowing DIE_BREAK to be used for any additional break numbers, i.e. it is no longer kprobes specific. Hooks for kernel debuggers and kernel dumpers added, ENTER and LEAVE. Both of these disable the system for long periods which impact on watchdogs and heartbeat systems in general. More patches to come that use these events to reset watchdogs and heartbeats. unregister_die_notifier() added and both routines exported. Requested by Dean Nelson. Lock removed from {un,}register_die_notifier. notifier_chain_register() already takes a lock. Also the generic notifier chain locking is being reworked to distinguish between callbacks that can block and those that cannot, the lock in {un,}register_die_notifier would interfere with that change. http://marc.theaimsgroup.com/?l=linux-kernel&m=113018709002036&w=2 Leading white space removed from arch/ia64/kernel/kprobes.c. Typo in mca.c in original version of this patch found & fixed by Dean Nelson.

The bootmem allocator only allows a power of two alignments. This causes a BUG_ON for some nodes. For cpu only nodes just allocate with a PERCPU_PAGE_SIZE alignment. Some older firmware reports SLIT distances of 0xff and results in bestnode not being computed. This is now treated correctly. The failed allocation check was removed because it's redundant. The bootmem allocator already makes this check. This fix has been boot tested on 4 node machine which has 4 cpu only nodes and 1 memory node. Thanks to Pete Keilty for reporting this and helping me test it. Signed-off-by: Bob Picco <bob.picco@hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
