Hi Joonas:
Thanks for the introduction. I have been thinking about the possibility of
introducing GEM_BUG_ON into GVT-g recently and investigating on it. I'm just a
bit confused about the usage between GEM_BUG_ON and WARN_ON.
GEM_BUG_ON is only enabled when kernel debug is enabled, which mostly

The cached node mechanism provides a significant performance benefit for

or where the 32-bit space is full, the loss of this benefit can be
significant - on large systems there can be many thousands of entries in

Now that the cached node optimisation can apply to all allocations, the
couple of users which were playing tricks with dma_32bit_pfn in order to
benefit from it can stop doing so. Conversely, there is also no need for
all the other users to explicitly calculate a 'real' 32-bit PFN,
Add a permanent dummy IOVA reservation to the rbtree, such that we can

simplifications.

I found myself about to add a driver that was a sub-optimal clone of
uio_pdrv_genirq the only difference was that I didn't want to modify the args
passed to the kernel by my bootloader. If uio_pdrv_genirq had a default
of_match entry I could simply use that. This series attempts to implement this.
Add a default compatible string "linux,uio-pdrv-genirq" to
uio_pdrv_genirq to make it usable without supplying a module parameter.
The module parameter is still supported in addition to the default.

The commit log is weirdly indented and no need to have "wireless:
broadcom:" in the title. I can fix both of those.

After the first few months, the message has not led to many bug reports.
It's been almost five years now, and in practice the main source of
