2007-06-26x86_64 irq: use mask/unmask and proper locking in fixup_irqs()Siddha, Suresh B1-3/+29
Force irq migration path during cpu offline, is not using proper locks and irq_chip mask/unmask routines. This will result in some races(especially the device generating the interrupt can see some inconsistent state, resulting in issues like stuck irq,..). Appended patch fixes the issue by taking proper lock and encapsulating irq_chip set_affinity() with a mask() before and an unmask() after. This fixes a MSI irq stuck issue reported by Darrick Wong. There are several more general bugs in this area(irq migration in the process context). For example, 1. Possibility of missing edge triggered irq. 2. Reliable method of migrating level triggered irq in the process context. We plan to look and close these in the near future. Eric says: In addition even with the fix from Suresh there is still at least one nasty hardware race in fixup_irqs(). However we exercise that code path rarely enough that we are unlikely to hit it in the real world, and that race seems to have existed since the code was merged. And a fix for that is not coming soon as it is an open investigation area if we can fix irq migration to work outside of irq context or if we have to rework the requirements imposed by the generic cpu hotplug and layer on fixup_irqs(). So this may come up again. Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Cc: Eric W.

This one changes the SN2 specific PCI drivers to use ioremap() for obtaining the real address to access for the PCI registers instead of manually calculating them with __IA64_UNCACHED_OFFSET.

2007-06-26[POWERPC] Fix subtle FP state corruption bug in signal return on SMPPaul Mackerras1-3/+7
This fixes a bug which can cause corruption of the floating-point state on return from a signal handler. If we have a signal handler that has used the floating-point registers, and it happens to context-switch to another task while copying the interrupted floating-point state from the user stack into the thread struct (e.g. because of a page fault, or because it gets preempted), the context switch code will think that the FP registers contain valid FP state that needs to be copied into the thread_struct, and will thus overwrite the values that the signal return code has put into the thread_struct. This can occur because we clear the MSR bits that indicate the presence of valid FP state after copying the state into the thread_struct. To fix this we just move the clearing of the MSR bits to before the copy. A similar potential problem also occurs with the Altivec state, and this fixes that in the same way.

2007-06-26[POWERPC] Fix VDSO gettimeofday() when called with NULL struct timevalTony Breeds2-4/+7
Consider the prototype for gettimeofday(): int gettimofday(struct timeval *tv, struct timezone *tz); Although it is valid to call with /either/ tv or tz being NULL, and the C version of sys_gettimeofday() supports this, the current version of gettimeofday() in the VDSO will SEGV if called with a NULL tv. This adds a check for tv being NULL so that it doesn't SEGV.

2007-06-24ACPI: preserve the ebx value in acpi_copy_wakeup_routineTian Kevin1-0/+2
Register %ebx serves as the "global offset table base register" for position-independent code. For absolute code, %ebx serves as a local register and has no specified role in the function calling sequence. In either case, a function must preserve the register value for the caller. acpi_copy_wakeup_routine overrides %ebx without saving it, this may corrupt the called data. Kevin found that most time the value of Sx is saved in %esi, however sometimes compiler also uses %ebx. When this happens, suspends fails since sleep value in ebx is changed by acpi_copy_wakeup_routine. The same funtion in X86_64 doesn't have this problem.

2007-06-24x86_64: fix misplaced `continue' in mce.cJoshua Wise1-2/+4
Background: When a userspace application wants to know about machine check events, it opens /dev/mcelog and does a read(). Usually, we found that this interface works well, but in some cases, when the system was taking large numbers of machine check exceptions, the read() would hang. The system would output a soft-lockup warning, and the daemon reading from /dev/mcelog would suck up as much of a single CPU as it could spinning in system space. Description: This patch fixes this bug. In particular, there was a "continue" inside a timeout loop that presumably was intended to break out of the outer loop, but instead caused the inner loop to continue. This patch also makes the condition for the break-out a little more evident by changing a !time_before to a time_after_eq. Result: The read() no longer hangs in this test case. Testing: On my system, I could replicate the bug with the following command: # for i in `seq 15000`; do ./inject_sbe.sh; done where inject_sbe.sh contains commands to inject a single-bit error into the next memory write transaction. Patch: This patch is against git f1518a088bde6aea49e7c472ed6ab96178fcba3e.

Hopefully this fixes http://bugzilla.kernel.org/show_bug.cgi?id=8635 The struct in6_addr passed to csum_ipv6_magic() is 4 byte aligned, so we can't use the regular 64-bit loads. Since the cost of handling of 4 byte and 1 byte aligned 64-bit data is roughly the same, this code can cope with any src/dst [mis]alignment.

If (start + size) is not cacheline aligned and (start & mask) > (end & mask), the last but one cacheline won't be invalidated as it should. Fix this by rounding `end' down to the nearest cacheline boundary if it gets adjusted due to misalignment. Also flush the write buffer unconditionally -- if the dcache wrote back a line just before we invalidated it, the dirty data may be sitting in the write buffer waiting to corrupt our buffer later.
