Please apply db05ddf7f32 to 5.4.x and 5.10.x

Please apply:

db05ddf7f32 ("ipmi:watchdog: Set panic count to proper value on a panic to stable kernel")

to the stable branches from 5.4.x to 5.10.x.

It requires as a pre-requisite:

a01a89b1db ("ipmi/watchdog: replace atomic_add() and atomic_sub()")

This change went in to 5.16 and a backport war requested and put into 5.15. It was missed in the earlier kernels; it didn't apply because the prerequisite was missed. It fixes a lockup at panic time. I think distros have picked it up, but I had a user report this.

Thank you,
