It would be nice to have the hack more localized to parisc
and guarded with a CONFIG_GCC_VERSION check so we can kill
it off in the future, once we drop either gcc-10 or parisc
support.
I vote for dropping parisc -- it's the only 64bit arch that doesn't have
sane atomics.
Of course I'm against dropping parisc.

Anyway, the below seems to work -- build tested with GCC-10.1
I don't think we need to care about gcc-10 on parisc.
Debian and Gentoo are the only supported distributions, while Debian
requires gcc-12 to build > 6.x kernels, and I assume Gentoo uses at least
gcc-12 as well.
So raising the gcc limit for parisc only (at least temporarily for now)
should be fine and your workaround below wouldn't be necessary, right?
Correct, if you're willing to set minimum GCC version to 11 for parisc
all is well and this patch can go play in the bit bucket.
