Thanks, it looks good to me.

Well big NAK to that! Direct I/O is intentionally disabled

Move logo rectangle initialisation, and logo drawing in separate
functions, so they can be re-used by different panic screens.
It prepares the introduction of the QR code panic screen.

This patch adds a new panic screen, with a QR code and the kmsg data
embedded.
If DRM_PANIC_SCREEN_QR_CODE_URL is set, then the kmsg data will be
compressed with zlib and encoded as a numerical segment, and appended
to the URL as a URL parameter. This allows to save space, and put
about ~7500 bytes
Check if two rectangles overlap.
It's a bit similar to drm_rect_intersect() but this won't modify
the rectangle.
Simplifies a bit drm_panic.

Add a parameter to the blit function, to upscale the image.
This is necessary to draw a QR code, otherwise, the pixels are
usually too small to be readable by most QR code reader.
It can also be used later for drawing fonts on high DPI display.

This series adds a new panic screen, with the kmsg data embedded in a QR code.
The main advantage of QR code, is that you can copy/paste the debug data to a
bug report.
The QR code encoder is written in rust, and is very specific to drm panic.
The reason is that it is called in a panic handler,
