Merge tag 'kgdb-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux
Pull kgdb updates from Daniel Thompson:
"Changes for kgdb/kdb this cycle are dominated by a change from Sumit
that removes as small (256K) private heap from kdb. This is change
I've hoped for ever since I discovered how few users of this heap
remained in the kernel, so many thanks to Sumit for hunting these
down.
The other change is an incremental step towards SPDX headers"
