2008-06-11[IA64] Update check_sal_cache_flush to use platform_send_ipi()Alex Chiang
check_sal_cache_flush is used to detect broken firmware that drops pending interrupts. The old implementation schedules a timer interrupt for itself in the future by getting the current value of the Interval Timer Counter + 1000 cycles, waits for the interrupt to be pended, calls SAL_CACHE_FLUSH, and finally checks to see if the interrupt is still pending. This implementation can cause problems for virtual machine code if the process of scheduling the timer interrupt takes more than 1000 cycles; the virtual machine can end up sleeping for several hundred years while waiting for the ITC to wrap around. The fix is to use platform_send_ipi. The processor will still send an interrupt to itself, using the IA64_IPI_DM_INT delivery mode, which causes the IPI to look like an external interrupt. The rest of the SAL_CACHE_FLUSH + checking to see if the interrupt is still pending remains unchanged. This fix has been boot tested successfully on: - intel tiger2 - hp rx6600 - hp rx5670 The rx5670 has known buggy firmware, where SAL_CACHE_FLUSH drops pending interrupts. A boot test on this machine showed this message on the console: SAL: SAL_CACHE_FLUSH drops interrupts; PAL_CACHE_FLUSH will be used instead Which proves that the self-inflicted IPI approach is viable. And as expected, the other tested platforms correctly did not display the warning. Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
2008-06-11[IA64] perfmon: fix async exit bugstephane eranian
Move the cleanup of the async queue to the close callback from the flush callback. This avoids losing asynchronous overflow notifications when the file descriptor is shared by multiple processes and one terminates.

2008-06-09Fix invalid access errors in blk_lookup_devtLinus Torvalds
Commit 30f2f0eb4bd2c43d10a8b0d872c6e5ad8f31c9a0 ("block: do_mounts - accept root=<non-existant partition>") extended blk_lookup_devt() to be able to look up partitions that had not yet been registered, but in the process made the assumption that the '&block_class.devices' list only contains disk devices and that you can do 'dev_to_disk(dev)' on them. That isn't actually true. The block_class device list also contains the partitions we've discovered so far, and you can't just do a 'dev_to_disk()' on those. So make sure to only work on devices that block/genhd.c has registered itself, something we can test by checking the 'dev->type' member. This makes the loop in blk_lookup_devt() match the other such loops in this file. [ We may want to do an alternate version that knows to handle _either_ whole-disk devices or partitions, but for now this is the minimal fix for a series of crashes reported by Mariusz Kozlowski in http://lkml.org/lkml/2008/5/25/25 and Ingo in http://lkml.org/lkml/2008/6/9/39 ] Reported-by: Mariusz Kozlowski <m.kozlowski@tuxland.pl> Reported-by: Ingo Molnar <mingo@elte.hu> Cc: Neil Brown <neilb@suse.de> Cc: Joao Luis Meloni Assirati <assirati@nonada.if.usp.br> Acked-by: Kay Sievers <kay.sievers@vrfy.org> Cc: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-06-09IB/core: Remove IB_DEVICE_SEND_W_INV capability flagRoland Dreier
In 2.6.26, we added some support for send with invalidate work requests, including a device capability flag to indicate whether a device supports such requests. However, the support was incomplete: the completion structure was not extended with a field for the key contained in incoming send with invalidate requests. Full support for memory management extensions (send with invalidate, local invalidate, fast register through a send queue, etc) is planned for 2.6.27. Since send with invalidate is not very useful by itself, just remove the IB_DEVICE_SEND_W_INV bit before the 2.6.26 final release; we will add an IB_DEVICE_MEM_MGT_EXTENSIONS bit in 2.6.27, which makes things simpler for applications, since they will not have quite as confusing an array of fine-grained bits to check.

Now that walk_memory_resource() is available regardless of MEMORY_HOTPLUG's setting, this dependency is not needed. Signed-off-by: Nathan Lynch <ntl@pobox.com> Acked-by: Jeff Garzik <jeff@garzik.org> Acked-by: Yasunori Goto <y-goto@jp.fujitsu.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2008-06-09[POWERPC] Make walk_memory_resource available with MEMORY_HOTPLUG=nNathan Lynch
The ehea driver was recently changed[1] to use walk_memory_resource() to detect the system's memory layout. However, walk_memory_resource() is available only when memory hotplug is enabled. So CONFIG_EHEA was made to depend on MEMORY_HOTPLUG [2], but it is inappropriate for a network driver to have such a dependency. Make the declaration of walk_memory_resource() and its powerpc implementation (ehea is powerpc-specific) unconditionally available.

2008-06-09[POWERPC] Fix incorrect enabling of VMX when building signal or user contextBenjamin Herrenschmidt
When building a signal or a ucontext, we can incorrectly set the MSR_VEC bit of the kernel pt_regs->msr before returning to userspace if the task -ever- used VMX. This can lead to funny result if that stack used it in the past, then "lost" it (ie. it wasn't enabled after a context switch for example) and then called get_context. It can end up with VMX enabled and the registers containing values from some other task.
