type in argument 1 (incompatible argument 1 (different address spaces))
Hi Christophe,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: a6afa4199d3d038fbfdff5511f7523b0e30cb774
commit: 2255411d1d0f0661d1e5acd5f6edf4e6652a345a powerpc/44x: Fix build failure with GCC 12 (unrecognized opcode: `wrteei')
