crtc_state is accessed by both vblank_handle() and the ordered
work_struct handle vkms_crc_work_handle() to retrieve and or update
the frame number for computed CRC.
Since work_struct can fail, add frame_end to account for missing frame
numbers.
Use (frame_[start/end]) for synchronization between hrtimer callback
and ordered work_struct handle.
This patch passes the following subtests from igt kms_pipe_crc_basic test:
bad-source, read-crc-pipe-A, read-crc-pipe-A-frame-sequence,
nonblocking-crc-pipe-A, nonblocking-crc-pipe-A-frame-sequence

Some Rockchip CRTCs, like rv1108 and px30, can directly output parallel
and serial RGB data to panel or conversion chip.
So add a feature-bit for vops to mark the ability for these direct
outputs and add an internal encoder in that case, that can attach to
bridge chipsor panels.
Changes in v7:
1. forget to delete rockchip_rgb_driver and delete it.
Changes in v6:
1. Update according to Heiko Stuebner' implemention, rgb output is
part of vop's feature, should not register as a independent
driver.
Changes in v5:
1. add SPDX-License-Identifier tag
Changes in v4:
1. add support px30;
Changes in v3:
1. update for rgb-mode move to panel node.
Changes in v2:
1. add error log when probe failed;
2. update name_to_output_mode() according to sean's suggest;
3. Fix uninitialized use of ret.

To be able to have both internal subdrivers and external bridge
drivers as output endpoints of vops, add a function to be able
to distinguish these.
changes in v8:
- improved function documentation
- better error handling
- put calls for node and pdev references
changes in v6:
- added function to check subdriver vs. bridge

"crtc->helper_private" is not initialized by the QXL driver and thus the
"crtc_funcs->disable" call would crash (resulting in suspend failure).
Fix this by converting the suspend/resume functions to use the
drm_mode_config_helper_* helpers.
Tested system sleep with QEMU 3.0 using "echo mem > /sys/power/state".
During suspend the following message is visible from QEMU:
spice/server/display-channel.c:2425:display_channel_validate_surface: canvas address is 0x7fd05da68308 for 0 (and is NULL)
spice/server/display-channel.c:2426:display_channel_validate_surface: failed on 0
This seems to be triggered by QXL_IO_NOTIFY_CMD after
QXL_IO_DESTROY_PRIMARY_ASYNC, but aside from the warning things still
seem to work (tested with both the GTK and -spice options).

The ioctl arguments are under control of the user and as such we should
resist any temptation to flood the kernel logs with their errors.
Relegate the DRM_ERROR to a DRM_DEBUG so the user has to opt into
hearing of their own mistakes. (One day we will have a small ringbuffer
attached to the task, so that the concerned process can inspect its own
debug info for EINVAL without them being hitting syslog at all.)

text_poke() functions
- Repair the fallout of giving native_restore_fl() a prototype

The trick with flipping bit 63 to avoid loading the address of the 1:1
mapping of the poisoned page while the 1:1 map is updated used to work when
unmapping the page. But it falls down horribly when attempting to directly
set the page as uncacheable.
The problem is that when the cache mode is changed to uncachable, the pages
needs to be flushed from the cache first. But the decoy address is
non-canonical due to bit 63 flipped, and the CLFLUSH instruction throws a
#GP fault.
Add code to change_page_attr_set_clr() to fix the address before calling
flush.

When PTI is enabled on x86-32 the kernel uses the GDT mapped in the fixmap
for the simple reason that this address is also mapped for user-space.
The efi_call_phys_prolog()/efi_call_phys_epilog() wrappers change the GDT
to call EFI runtime services and switch back to the kernel GDT when they
return. But the switch-back uses the writable GDT, not the fixmap GDT.
When that happened and and the CPU returns to user-space it switches to the
user %cr3 and tries to restore user segment registers. This fails because
the writable GDT is not mapped in the user page-table, and without a GDT
the fault handlers also can't be launched. The result is a triple fault and
reboot of the machine.
Fix that by restoring the GDT back to the fixmap GDT which is also mapped
in the user page-table.
