| * [ARM] Acorn: move the i2c bus driver into drivers/i2cRussell King2007-03-047-694/+108
| | | | | | | | | | | | | | | | Move the Acorn IOC/IOMD I2C bus driver from drivers/i2c, strip out the reminants of the platform specific parts of the old PCF8583 RTC code, and remove the old obsolete PCF8583 driver. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * [ARM] ARM SCSI: Don't try to dma_map_sg too many scatterlist entriesRussell King2007-03-043-6/+7
| | | | | | | | | | | | | | | | | | | | An off-by-one bug meant we were always trying to map one too many scatterlist entries. This was mostly harmless prior to the checks going in to consistent_sync(), but now causes the kernel to BUG. Also, powertec.c was missing an assignment to info->ec.

| * [ARM] ARM FAS216: don't modify scsi_cmnd request_bufflenRussell King2007-03-042-4/+7
| | | | | | | | | | | | | | SCSI doesn't want drivers to modify request_bufflen, so keep a driver-private copy of this in the scsi_pointer structure instead. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * [ARM] rtc-pcf8583: Final fixes for this RTC on RiscPCRussell King2007-03-042-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace the I2C bus address, as per drivers/acorn/char/pcf8583.c. Also, since this driver also contains Acorn RiscPC specific code for obtaining the current year from the SRAM (and updating the platform specific checksum when writing new data back) this is NOT a platform independent driver. Document it as such, and update the dependencies to reflect this fact. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| * [ARM] rtc-pcf8583: don't use BCD_TO_BIN/BIN_TO_BCDRussell King2007-03-041-10/+10
| | | | | | | | | | | | | | | | | | | | Both BCD_TO_BIN(x) and BIN_TO_BCD(x) have an unexpected side-effect - not only do they return the value as expected, they _modify_ their argument in the process. Let's play it safe and avoid these macros. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* | KVM: Fix bogus failure in kvm.ko module initializationAvi Kivity2007-03-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | A bogus 'return r' can cause an otherwise successful module load to fail. This both denies users the use of kvm, and it also denies them the use of their machine, as it leaves a filesystem registered with its callbacks pointing into now-freed module memory. Fix by returning a zero like a good module. Thanks to Richard Lucassen <mailinglists@lucassen.org> (?) for reporting the problem and for providing access to a machine which exhibited it.

* | KVM: Remove write access permissions when dirty-page-logging is enabledUri Lublin2007-03-041-0/+2
| | | | | | | | | | | | | | | | | | Enabling dirty page logging is done using KVM_SET_MEMORY_REGION ioctl. If the memory region already exists, we need to remove write accesses, so writes will be caught, and dirty pages will be logged.

* | KVM: Fix dirty page log bitmap size/access calculationUri Lublin2007-03-041-2/+2
| | | | | | | | | | | | | | | | Since dirty_bitmap is an unsigned long array, the alignment and size need to take that into account. Signed-off-by: Uri Lublin <uril@qumranet.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
* | KVM: Add missing calls to mark_page_dirty()Uri Lublin2007-03-041-0/+6
| | | | | | | | | | | | | | | | A few places where we modify guest memory fail to call mark_page_dirty(), causing live migration to fail. This adds the missing calls. Signed-off-by: Uri Lublin <uril@qumranet.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
* | KVM: Per-vcpu inodesAvi Kivity2007-03-044-119/+153
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allocate a distinct inode for every vcpu in a VM. This has the following benefits: - the filp cachelines are no longer bounced when f_count is incremented on every ioctl() - the API and internal code are distinctly clearer; for example, on the KVM_GET_REGS ioctl, there is no need to copy the vcpu number from userspace and then copy the registers back; the vcpu identity is derived from the fd used to make the call Right now the performance benefits are completely theoretical since (a) we don't support more than one vcpu per VM and (b) virtualization hardware inefficiencies completely everwhelm any cacheline bouncing effects. But both of these will change, and we need to prepare the API today. Signed-off-by: Avi Kivity <avi@qumranet.com>

* | KVM: Rename some kvm_dev_ioctl_*() functions to kvm_vm_ioctl_*()Avi Kivity2007-03-041-24/+24
| | | | | | | | | | | | | | This reflects the changed scope, from device-wide to single vm (previously every device open created a virtual machine). Signed-off-by: Avi Kivity <avi@qumranet.com>
* | KVM: Create an inode per virtual machineAvi Kivity2007-03-041-41/+171
| | | | | | | | | | | | | | | | | | | | This avoids having filp->f_op and the corresponding inode->i_fop different, which is a little unorthodox. The ioctl list is split into two: global kvm ioctls and per-vm ioctls. A new ioctl, KVM_CREATE_VM, is used to create VMs and return the VM fd. Signed-off-by: Avi Kivity <avi@qumranet.com>
* | KVM: Add internal filesystem for generating inodesAvi Kivity2007-03-041-1/+32
| | | | | | | | | | | | | | The kvmfs inodes will represent virtual machines and vcpus, as necessary, reducing cacheline bouncing due to inodes and filps being shared. Signed-off-by: Avi Kivity <avi@qumranet.com>

| * | [libata] change master/slave IDENTIFY orderJeff Garzik2007-03-021-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2.6.21-rc has horrible problems with libata and PATA cable types (and thus speeds). This occurs because Tejun fixed a pile of other bugs and we now do cable detect enforcement for drive side detection properly. Unfortunately we don't do the process around cable detection right. Tejun identified the problem and pointed to the right Annex in the spec, this patch implements the needed changes. The basic requirement is that we have to identify the slave before the master. The patch switches the identify order so that we can do the drive side detection correctly.

| * | libata-core: Fix simplex handlingAlan2007-03-021-3/+2
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The initial simplex handling code is fooled if you suspend and resume. This also causes problems with some single channel controllers which claim to be simplex. The fix is fairly simple, instead of keeping a flag to remember if we gave away the simplex channel we remember the actual owner. As the owner is always part of the host_set we don't even need a refcount. Knowing the owner also means we can reassign simplex DMA channels in future hotplug code etc if we need to Signed-off-by: Alan Cox <alan@redhat.com> (and a signed-off for the patch I sent before while I remember) Signed-off-by: Jeff Garzik <jeff@garzik.org>
