| | | | | | | | | | | | | | | | | | | | | | | | The function type_check() in aicasm grammar code was never used properly due to a bug. This patch fixes it up and ensures it's only called if appropriate. In addition the unused 16bit instruction are disabled, but left in the code for reference.

| * [SCSI] fix SLUB WARN_ONJames Bottomley2008-04-271-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We're getting a WARN_ON from SLUB indicating that we're trying to free caches with in-use objects. The root cause is a new dependency in the command/sense free on unchecked_isa_dma. The WARN_ON is caused by drivers which change this in their setup after the command/sense cache is allocated. The fix is to move the allocation of this cache into scsi_add_host() so things like gdth have an opportunity to modify it between alloc and add (but *not* after). The true fix would be to move unchecked_isa_dma into the template and out of the host, so it because a truly read only variable. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - remove pointless casts from void* - remove needless references to 'irq' function argument, when that information is already stored somewhere in a driver-private struct. - where the 'irq' function argument is known never to be used, rename it to 'dummy' to make this more obvious - remove always-false tests for dev_id==NULL - remove always-true tests for 'irq == host_struct->irq' - replace per-irq lookup functions and tables with a direct reference to data object obtained via 'dev_id' function argument, passed from request_irq() This change's main purpose is to prepare for the patchset in jgarzik/misc-2.6.git#irq-remove, that explores removal of the never-used 'irq' argument in each interrupt handler.

| * [SCSI] aic79xx: fix MMIO for PPC 44x platformsSergei Shtylyov2008-04-242-15/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver stores the PCI resource address into 'u_long' variable before calling ioremap_nocache() on it. This warrants kernel oops when the registers are accessed on PPC 44x platforms which (being 32-bit) have PCI memory space mapped beyond 4 GB. The arch/ppc/ kernel has a fixup in ioremap() that helps create an illusion that the PCI memory resources are mapped below 4 GB, but arch/powerpc/ code got rid of this trick, having instead CONFIG_RESOURCES_64BIT enabled.

| * [SCSI] scsi_transport_sas: fix the lifetime of sas bsg objectsFUJITA Tomonori2008-04-221-2/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | scsi_transport_sas calls blk_cleanup_queue too early for bsg queues. If a user holds a sas_host, end_device, or expander device open, remove the device, then send a request to it, we get a kernel crash. We need to call blk_cleanup_queue in the release callback as we do with scsi devices. This patch moves blk_cleanup_queue to sas_expander_release and sas_end_device_release from sas_bsg_remove. sas_host can't use the release callback in struct device so use bsg's release callback.

| * [SCSI] bsg: add release callback supportFUJITA Tomonori2008-04-224-20/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds release callback support, which is called when a bsg device goes away. bsg_register_queue() takes a pointer to a callback function. This feature is useful for stuff like sas_host that can't use the release callback in struct device. If a caller doesn't need bsg's release callback, it can call bsg_register_queue() with NULL pointer (e.g. scsi devices can use release callback in struct device so they don't need bsg's callback). With this patch, bsg uses kref for refcounts on bsg devices instead of get/put_device in fops->open/release. bsg calls put_device and the caller's release callback (if it was registered) in kref_put's release.

| * [SCSI] rework scsi_target allocationJames Bottomley2008-04-223-39/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current target allocation code registeres each possible target with sysfs; it will be deleted again if no useable LUN on this target was found. This results in a string of 'target add/target remove' uevents. Based on a patch by Hannes Reinecke <hare@suse.de> this patch reworks the target allocation code so that only uevents for existing targets are sent. The sysfs registration is split off from the existing scsi_target_alloc() into a in a new scsi_add_target() function, which should be called whenever an existing target is found. Only then a uevent is sent, so we'll be generating events for existing targets only. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | We have a problem in scsi_transport_spi in that we need to customise not only the visibility of the attributes, but also their mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is not selective cr0 intercept bug. The code in the comment sets the CR0.PG bit. But KVM sets the CR4.PG bit for SVM always to implement the paged real mode. So the 'mov %eax,%cr0' instruction does not change the CR0.PG bit. Selective CR0 intercepts only occur when a bit is actually changed. So its the right behavior that there is no intercept on this instruction.

| * | KVM: SVM: add intercept for machine check exceptionJoerg Roedel2008-04-272-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | To properly forward a MCE occured while the guest is running to the host, we have to intercept this exception and call the host handler by hand. This is implemented by this patch. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
| * | KVM: SVM: align shadow CR4.MCE with hostJoerg Roedel2008-04-271-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | This patch aligns the host version of the CR4.MCE bit with the CR4 active in the guest. This is necessary to get MCE exceptions when the guest is running. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
| * | KVM: SVM: indent svm_set_cr4 with tabs instead of spacesJoerg Roedel2008-04-271-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | The svm_set_cr4 function is indented with spaces. This patch replaces them with tabs. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
