* [PATCH] uml: fix mcast network driver error handlingPaolo 'Blaisorblade' Giarrusso2005-11-13
| | | | | | | | | | | | | | | | | | | printk clears the host errno (I verified this in debugging and it's reasonable enough, given that it ends via a write call on some fd, especially since printk() goes on /dev/tty0 which is often the host stdout). So save errno earlier. There's no reason to change the printk calls to use -err rather than errno - the assignment can't clear errno. And in the first failure path, we used to return 0 too (and this time more clearly), which is totally wrong. 0 is a success fd, which is then registered and gives a "registering fd twice" warning. Finally, fix up some whitespace.

| | | | | | | | | | | | A few fixups - show the new submenu only for x86 subarchitecture (it does not make sense to show it for x86_64 users) and remove X86_CMPXCHG, which is now a duplicate of Kconfig.i386, even though Kconfig doesn't complain (we also miss the dependency on !M386 CPU).

* [PATCH] uml: remove bogus WARN_ON, triggerable harmlessly on a page fault racePaolo 'Blaisorblade' Giarrusso2005-11-13
| | | | | | | | | | | | | | | | | | | | | | The below warning was added in place of pte_mkyoung(); if (is_write) pte_mkdirty(); In fact, if the PTE is not marked young/dirty, our dirty/accessed bit emulation would cause the TLB permission not to be changed, and so we'd loop, and given we don't support preemption yet, we'd busy-hang here. However, I've seen this warning trigger without crashes during a loop of concurrent kernel builds, at random times (i.e. like a race condition), and I realized that two concurrent faults on the same page, one on read and one on write, can trigger it. The read fault gets serviced and the PTE gets marked writable but clean (it's possible on a shared-writable mapping), while the generic code sees the PTE was already installed and returns without action. In this case, we'll see another fault and service it normally.

* [PATCH] m68k: convert thread flags to use bit fieldsRoman Zippel2005-11-13
| | | | | | | | | | | | | | | Remove task_work structure, use the standard thread flags functions and use shifts in entry.S to test the thread flags. Add a few local labels to entry.S to allow gas to generate short jumps. Finally it changes a number of inline functions in thread_info.h to macros to delay the current_thread_info() usage, which requires on m68k a structure (task_struct) not yet defined at this point.

* [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.

* | [PATCH] PCI: fix for Toshiba ohci1394 quirkJesse Barnes2005-11-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | Move the PPC fixup for old NCR 810 controllers to generic quirks - it's needed for Alpha, x86 and other architectures that use setup-bus.c. Thanks to Jay Estabrook for pointing out the issue. Signed-off-by: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | XPC (as in arch/ia64/sn/kernel/xp*) has a need to notify other partitions (SGI Altix) whenever a partition is going down in order to get them to disengage from accessing the halting partition's memory. If this is not done before the reset of the hardware, the other partitions can find themselves encountering MCAs that bring them down.
