I am having problems with following commit
aed44286efa8ae8717a77d94b51ac3614e2ca6dc. 

When trying to build the Linux kernel I get a lot of:
./arch/riscv/include/asm/irqflags.h:34: Error: unrecognized opcode
`csrrc s2,0x100,2'
./arch/riscv/include/asm/irqflags.h:52: Error: unrecognized opcode
`csrs 0x100,s2'

The kernel is compiled with gcc 11.2 and  -mabi=lp64 -march=rv64ima.

When I revert the commit, everything is fine.

What can we do about it?

best regards
 Waldemar
