[IA64] xen: fix xen_get_eflags.

2008-11-20T21:43:01Z

fix xen_get_eflags. It doesn't take any argument. Signed-off-by: Isaku Yamahata Signed-off-by: Tony Luck

[IA64] ia64/pv_ops/pv_cpu_ops: fix _IA64_REG_IP case.

2008-11-20T21:41:20Z

pv_cpu_ops.getreg(_IA64_REG_IP) returned constant. But the returned ip valued should be the one in the caller, not of the callee. This patch fixes that. Signed-off-by: Isaku Yamahata Signed-off-by: Tony Luck

[IA64] remove duplicate include iommu.h

2008-11-20T21:38:16Z

arch/ia64/kernel/pci-dma.c only needs to include iommu once. Signed-off-by: Huang Weiyi Signed-off-by: Tony Luck

[IA64] use mprintk instead of printk, in ia64_mca_modify_original_stack

2008-11-20T21:31:10Z

Using printk from MCA/INIT context is unsafe since it can cause deadlock. The ia64_mca_modify_original_stack is called from both of mca handler and init handler, so it should use mprintk instead of printk. Signed-off-by: Hidetoshi Seto Signed-off-by: Tony Luck

[IA64] Rationalize kernel mode alignment checking

2008-11-20T21:27:12Z

Itanium processors can handle some misaligned data accesses. They also provide a mode where all such accesses are forced to trap. The kernel was schizophrenic about use of this mode: * Base kernel code ran in permissive mode where the only traps generated were from those cases that the h/w could not handle. * Interrupt, syscall and trap code ran in strict mode where all unaligned accesses caused traps to the 0x5a00 unaligned reference vector. Use strict alignment checking throughout the kernel, but make sure that we continue to let user mode use more relaxed mode as the default. Signed-off-by: Tony Luck

x86: Fix interrupt leak due to migration

2008-11-20T21:17:40Z

When we migrate an interrupt from one CPU to another, we set the move_in_progress flag and clean up the vectors later once they're not being used. If you're unlucky and call destroy_irq() before the vectors become un-used, the move_in_progress flag is never cleared, which causes the interrupt to become unusable. This was discovered by Jesse Brandeburg for whom it manifested as an MSI-X device refusing to use MSI-X mode when the driver was unloaded and reloaded repeatedly.

SUNRPC: Fix a performance regression in the RPC authentication code

2008-11-20T21:17:40Z

Fix a regression reported by Max Kellermann whereby kernel profiling showed that his clients were spending 45% of their time in rpcauth_lookup_credcache. It turns out that although his processes had identical uid/gid/groups, generic_match() was failing to detect this, because the task->group_info pointers were not shared. This again lead to the creation of a huge number of identical credentials at the RPC layer. The regression is fixed by comparing the contents of task->group_info if the actual pointers are not identical. Signed-off-by: Trond Myklebust Signed-off-by: Linus Torvalds
