2019-09-16drm/amdgpu: Check for valid number of registers to readTrek
Do not try to allocate any amount of memory requested by the user. Instead limit it to 128 registers. Actually the longest series of consecutive allowed registers are 48, mmGB_TILE_MODE0-31 and mmGB_MACROTILE_MODE0-15 (0x2644-0x2673).

2019-09-16drm/radeon: Bail earlier when radeon.cik_/si_support=0 is passedHans de Goede
Bail from the pci_driver probe function instead of from the drm_driver load function. This avoid /dev/dri/card0 temporarily getting registered and then unregistered again, sending unwanted add / remove udev events to userspace. Specifically this avoids triggering the (userspace) bug fixed by this plymouth merge-request: https://gitlab.freedesktop.org/plymouth/plymouth/merge_requests/59 Note that despite that being an userspace bug, not sending unnecessary udev events is a good idea in general.

This reverts commit e01f2d41895102d824c6b8f5e011dd5e286d5e8b. VG20 did not require this workaround, as the fix is in the VBIOS.

2019-09-16drm/amdgpu: Fix mutex lock from atomic context.Andrey Grodzovsky
Problem: amdgpu_ras_reserve_bad_pages was moved to amdgpu_ras_reset_gpu because writing to EEPROM during ASIC reset was unstable. But for ERREVENT_ATHUB_INTERRUPT amdgpu_ras_reset_gpu is called directly from ISR context and so locking is not allowed. Also it's irrelevant for this partilcular interrupt as this is generic RAS interrupt and not memory errors specific. Fix: Avoid calling amdgpu_ras_reserve_bad_pages if not in task context.
