One more round of drm-misc, again mostly atomic. Big thing is the

now added to the atomic ioctl. Finally we can do atomic modesets!
Note that the atomic ioctl is still behind the module knob since the
weston patches aren't quite ready yet imo - they lack TEST_ONLY support,
which is a fairly crucial bit of the atomic api. But besides that I think
it's all good to go. That's also why we didn't bother to hide the new blob
ioctls behind the knob, that part won't need to change. And if weston
patches get in shape in time we could throw the "atomic by default patch"

- Add the H/W debugger support module, including new IOCTLs to:
- register/unregister a process as a debugged process
- Set address watch-point in the debugged process's GPU kernel
- Do a wave control operation in the debugged process's waves
See the commit messages for more details on the available operations.
The debugged process can only perform debug operation on itself. It is
blocked by the amdkfd+H/W from performing operations on other processes's
waves or GPU kernels. The blocking is done by setting the VMID and PASID of
the debugged process in the packets that are sent to the CP with the debug
instructions.
- Add support for static user-mode queues. These queues are regular queues,
but because they belong to the debugged process, we need to make sure the CP
doesn't preempt them during a debug operation. Therefore, we mark them as
static for the CP ignore them during preemption.
- Support killing all the waves when a process is terminated. This is needed
in case a process is terminated but we can't UNMAP its queues (can occur due
to several reasons). In that case, the CP could be stuck unless we kill all
its waves. This function is *very* important as it provides the kernel a high
level of control over the GPU. The reason we didn't upstream this function
so far, is because it is implemented using the H/W debugger module functions,
so we had to wait until we can upstream the H/W debugger module.

Add virtio gpu driver.
This patch adds a kms driver for the virtio gpu. The xorg modesetting
driver can handle the device just fine, the framebuffer for fbcon is
there too.
Qemu patches for the host side are under review currently.
The pci version of the device comes in two variants: with and without
vga compatibility. The former has a extra memory bar for the vga
framebuffer, the later is a pure virtio device. The only concern for
this driver is that in the virtio-vga case we have to kick out the
firmware framebuffer.

some more work on the qemu side and will be added later.

drm/amdkfd: add H/W debugger IOCTL set definitions
This patch adds four new IOCTLs to amdkfd. These IOCTLs expose a H/W
debugger functionality to the userspace.
The IOCTLs are:
- AMDKFD_IOC_DBG_REGISTER:
The purpose of this IOCTL is to notify amdkfd that a process wants to use
GPU debugging facilities on itself only.
It is expected that this IOCTL would be called before any other H/W
debugger requests are sent to amdkfd and for each GPU where the H/W
debugging needs to be enabled. The use of this IOCTL ensures that only
one instance of a debugger is active in the system.
- AMDKFD_IOC_DBG_UNREGISTER:
This IOCTL detaches the debugger/debugged process from the H/W
Debug which was established by the AMDKFD_IOC_DBG_REGISTER IOCTL.
- AMDKFD_IOC_DBG_ADDRESS_WATCH:
This IOCTL allows to set different watchpoints with various conditions as
indicated by the IOCTL's arguments. The available number of watchpoints
is retrieved from topology. This operation is confined to the current
debugged process, which was registered through AMDKFD_IOC_DBG_REGISTER.
- AMDKFD_IOC_DBG_WAVE_CONTROL:
This IOCTL allows to control a wavefront as indicated by the IOCTL's
arguments. For example, you can halt/resume or kill either a
single wavefront or a set of wavefronts. This operation is confined to
the current debugged process, which was registered through
AMDKFD_IOC_DBG_REGISTER.
Because the arguments for the address watch IOCTL and wave control IOCTL
are dynamic, meaning that they could vary in size, the userspace passes a
pointer to a structure (in userspace) that contains the value of the
arguments. The kernel driver is responsible to parse this structure and
validate its contents.

strictly rely on its second argument to be either NULL or a valid

As it turns out, pcibios_root_bridge_prepare() on x86 and ia64 works
with the assumption that the only code path calling pci_create_root_bus()
is pci_acpi_scan_root() and therefore the sysdata argument passed to
it will always match the expectations of pcibios_root_bridge_prepare().
That need not be the case, however, and in particular it is not the
case for the Xen pcifront driver that passes a pointer to its own
private data strcture as sysdata to pci_scan_bus_parented() which then
passes it to pci_create_root_bus() and it ends up being used incorrectly

dm: fix casting bug in dm_merge_bvec()
dm_merge_bvec() was originally added in f6fccb ("dm: introduce
merge_bvec_fn"). In that commit a value in sectors is converted to
bytes using << 9, and then assigned to an int. This code made
assumptions about the value of BIO_MAX_SECTORS.
A later commit 148e51 ("dm: improve documentation and code clarity in
dm_merge_bvec") was meant to have no functional change but it removed
the use of BIO_MAX_SECTORS in favor of using queue_max_sectors(). At
this point the cast from sector_t to int resulted in a zero value. The
fallout being dm_merge_bvec() would only allow a single page to be added
to a bio.
This interim fix is minimal for the benefit of stable@ because the more
comprehensive cleanup of passing a sector_t to all DM targets' merge
function will impact quite a few DM targets.

dm: fix reload failure of 0 path multipath mapping on blk-mq devices
dm-multipath accepts 0 path mapping.
# echo '0 2097152 multipath 0 0 0 0' | dmsetup create newdev
Such a mapping can be used to release underlying devices while still
holding requests in its queue until working paths come back.
However, once the multipath device is created over blk-mq devices,
it rejects reloading of 0 path mapping:
# echo '0 2097152 multipath 0 0 1 1 queue-length 0 1 1 /dev/sda 1' \
| dmsetup create mpath1
# echo '0 2097152 multipath 0 0 0 0' | dmsetup load mpath1
device-mapper: reload ioctl on mpath1 failed: Invalid argument
Command failed
With following kernel message:
device-mapper: ioctl: can't change device type after initial table load.
DM tries to inherit the current table type using dm_table_set_type()
but it doesn't work as expected because of unnecessary check about
whether the target type is hybrid or not.
Hybrid type is for targets that work as either request-based or bio-based
and not required for blk-mq or non blk-mq checking.

dm: fix false warning in free_rq_clone() for unmapped requests
When stacking request-based dm device on non blk-mq device and
device-mapper target could not map the request (error target is used,
multipath target with all paths down, etc), the WARN_ON_ONCE() in
free_rq_clone() will trigger when it shouldn't.
The warning was added by commit aa6df8d ("dm: fix free_rq_clone() NULL
pointer when requeueing unmapped request"). But free_rq_clone() with
clone->q == NULL is valid usage for the case where
dm_kill_unmapped_request() initiates request cleanup.
Fix this false warning by just removing the WARN_ON -- it only generated
false positives and was never useful in catching the intended case
(completing clone request not being mapped e.g. clone->q being NULL).

The count variable is used to iterate down to (below) zero from the size

partial bitmap block. The loop conditional expects count to be signed
in order to detect when the final block is processed, after which count
goes negative.
Unfortunately, a recent change made this unsigned along with some other
related fields. The result of is this is that during mount,
omfs_get_imap will overrun the bitmap array and corrupt memory unless
number of blocks happens to be a multiple of 8 * blocksize.
