[PATCH 0/8] Falcon library
...ad and execure code, and not care about implementation details.
This series also updates gr and secboot use the falcon library as an example.
Converting other engines is trivial and should make our use of falcons generally
safer.
Alexandre Courbot (8):
core: constify nv*_printk macros
mc: add nvkm_mc_enabled() function
core: add falcon library functions
secboot: use falcon library definitions
secboot: use falcon library
gr/gf100: split gf100_gr_init_ctxctl()
gr/gf100: use falcon library
secboot: remove nvkm_secboot_start()

[PATCH 0/8] Add workaround for fixing runpm
Changes since last sent:
* add a patch to set the device into DRM_SWITCH_POWER_CHANGING state
(can be dropped actually, I thought I was needing it, came up with a
different approach and forgot to delete it, doesn't hurt though)
* expose information about runtime suspending to nvkm so that we can run
the pcie workaround only on runtime suspend
