This is a note to let you know that I've just added the patch titled
genirq/affinity: Remove the 'firstvec' parameter from irq_build_affinity_masks
to the 6.1-stable tree which can be found at:
http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary
The filename of the patch is:
genirq-affinity-remove-the-firstvec-parameter-from-i.patch
and it can be found in the queue-6.1 subdirectory.
If you, or anyone else, feels it should not be added to the stable tree,
please let <stable@xxxxxxxxxxxxxxx> know about it.

genirq/affinity: Remove the 'firstvec' parameter from irq_build_affinity_masks
[ Upstream commit cdf07f0ea48a3b52f924714d477366ac510ee870 ]
The 'firstvec' parameter is always same with the parameter of
'startvec', so use 'startvec' directly inside irq_build_affinity_masks().
