| * [S390] cio: Fixup interface for setting options on ccw devices.Cornelia Huck2007-02-122-3/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current ccw_device_set_options() sets a specified mask of options and clears those not specified, but there is no way to find out which options have already been set. In order to fix this up, introduce the following interface changes: ccw_device_set_options() now only sets the specified bits, but does not clear those that are not specified. ccw_device_clear_options() clears the specified bits. ccw_device_set_options_mask() provides the old semantics (setting only the specified bits and clearing the others). Device drivers now work as expected. qdio has been adapted. Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
* | [PATCH] mark struct file_operations const 9Arjan van de Ven2007-02-122-2/+2
| | | | | | | | | | | | | | | | | | | | | | Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the PS3 Virtual Frame Buffer Driver. As the actual graphics hardware cannot be accessed directly by Linux, ps3fb uses a virtual frame buffer in main memory. The actual screen image is copied to graphics memory by the GPU on every vertical blank, by making a hypervisor call.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fb_videomode_to_var(): reset the virtual screen parameters when converting from an fb_videomode to an fb_var_screeninfo. Without this the old virtual screen parameters are kept. Hence you cannot switch to a video mode with a lower resolution on frame buffer devices that don't support virtual screens and panning, as values are not supposed to be rounded down when they don't fit. I also reordered the assignments to match the order of the individual members.

* | [PATCH] kvm: fix vcpu freeing bugIngo Molnar2007-02-121-1/+3
| | | | | | | | | | | | | | | | | | | | | | vcpu_load() can return NULL and it sometimes does in failure paths (for example when the userspace ABI version is too old) - causing a preemption count underflow in the ->vcpu_free() later on. So check for NULL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | We report the value of cr8 to userspace on an exit. Also let userspace change cr8 when we re-enter the guest. The lets 64-bit guest code maintain the tpr correctly. Thanks for Yaniv Kamay for the idea.

* | [PATCH] kvm: Fix mmu going crazy of guest sets cr0.wp == 0Avi Kivity2007-02-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | The kvm mmu relies on cr0.wp being set even if the guest does not set it. The vmx code correctly forces cr0.wp at all times, the svm code does not, so it can't boot solaris without this patch.

Use the opportunity to remove all the code duplication in gva_to_gpa(), which essentially repeats the calculations in walk_addr().
