2009-06-10KVM: Add MSI-X interrupt injection logicSheng Yang
We have to handle more than one interrupt with one handler for MSI-X. Avi suggested to use a flag to indicate the pending. So here is it. Signed-off-by: Sheng Yang <sheng@linux.intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2009-06-10KVM: Ioctls for init MSI-X entrySheng Yang
Introduce KVM_SET_MSIX_NR and KVM_SET_MSIX_ENTRY two ioctls. This two ioctls are used by userspace to specific guest device MSI-X entry number and correlate MSI-X entry with GSI during the initialization stage. MSI-X should be well initialzed before enabling. Don't support change MSI-X entry number for now. Signed-off-by: Sheng Yang <sheng@linux.intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2009-06-10KVM: bit ops for deliver_bitmapSheng Yang
It's also convenient when we extend KVM supported vcpu number in the future. Signed-off-by: Sheng Yang <sheng@linux.intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2009-06-10KVM: Update intr delivery func to accept unsigned long* bitmapSheng Yang
Would be used with bit ops, and would be easily extended if KVM_MAX_VCPUS is increased. Signed-off-by: Sheng Yang <sheng@linux.intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2009-06-10KVM: Change API of kvm_ioapic_get_delivery_bitmaskSheng Yang

2009-06-10KVM: Split IOAPIC structureSheng Yang

2009-06-10KVM: VMX: Don't intercept MSR_KERNEL_GS_BASEAvi Kivity
Windows 2008 accesses this MSR often on context switch intensive workloads; since we run in guest context with the guest MSR value loaded (so swapgs can work correctly), we can simply disable interception of rdmsr/wrmsr for this MSR. A complication occurs since in legacy mode, we run with the host MSR value loaded. In this case we enable interception. This means we need two MSR bitmaps, one for legacy mode and one for long mode. Signed-off-by: Avi Kivity <avi@redhat.com>
2009-06-10KVM: VMX: Don't use highmem pages for the msr and pio bitmapsAvi Kivity
Highmem pages are a pain, and saving three lowmem pages on i386 isn't worth the extra code. Signed-off-by: Avi Kivity <avi@redhat.com>
2009-06-10HID: fix inverted wheel for bluetooth version of apple mighty mouseJiri Kosina
Bluetooth version of Apple Mighty mouse (0x05ac/0x030c) doesn't, according to multiple reports on linux-input@, need the same quirk as the USB version of this mouse (0x05ac/0x0304) does. Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2009-06-10can: sja1000_of_platform: fix build problems with printk formatWolfgang Grandegger
According to "Documentation/printk-formats.txt", if the type is dependent on a config option for its size, like resource_size_t, we should use a format specifier of its largest possible type and explicitly cast to it.

2009-06-10sunrpc/auth_gss: Call rcu_barrier() on module unload.Jesper Dangaard Brouer
As the module uses rcu_call() we should make sure that all rcu callback has been completed before removing the code. Signed-off-by: Jesper Dangaard Brouer <hawk@comx.dk> Acked-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-06-10sctp: protocol.c call rcu_barrier() on unload.Jesper Dangaard Brouer
On module unload call rcu_barrier(), this is needed as synchronize_rcu() is not strong enough. The kmem_cache_destroy() does invoke synchronize_rcu() but it does not provide same protection.

2009-06-108021q: Vlan driver should use rcu_barrier() on unload instead of ↵Jesper Dangaard Brouer
syncronize_net() The VLAN 8021q driver needs to call rcu_barrier() when unloading the module, instead of syncronize_net(). This is needed to make sure that outstanding call_rcu() callbacks have completed, before the callback function code is removed on module unload.

2009-06-10qlge: Add support for varied pcie function numbers.Ron Mercer
Currently we support only PCIe NIC functions zero and one, and FCoE functions as 3 and 4. Future configurations can mix these up in any fashion. This patch removes the 0-1 dependancy and allows usage of any of the 4 functions. We also find the alternate NIC function (if exist) and determine our port number based on the comparison of the two functions: Lower function number gets first port, higher function gets second port.

2009-06-10qlge: Add support for using alternate MAC address.Ron Mercer
Extract either manufacturer or Bladecenter Open Fabric Manager (BOFM) MAC address. BOFM may indicate an alternate MAC address.

2009-06-09Make /dev/zero reads interruptible by signalsLinus Torvalds
This helps with bad latencies for large reads from /dev/zero, but might conceivably break some application that "knows" that a read of /dev/zero cannot return early. So do this early in the merge window to give us maximal test coverage, even if the patch is totally trivial. Obviously, no well-behaved application should ever depend on the read being uninterruptible, but hey, bugs happen. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
