build error while building arch/x86/purgatory/sha256.o: invalid 'asm': operand is not a condition code [...]

Hi! My linux-next builds for Fedora[1] since yesterday fail with the
following error:

> In file included from <command-line>:
> ./include/crypto/sha256_base.h: In function ‘lib_sha256_base_do_update.constprop.isra’:
> ././include/linux/compiler_types.h:332:20: error: invalid 'asm': operand is not a condition code, invalid operand code 'c'
>   332 | #define asm_inline asm __inline
>       |                    ^~~

See below for the full error message[2]. This happens on Fedora rawhide
and 38 (both use gcc13), but not on Fedora 37 (which uses gcc12).

Is this known already or do I have to bisect this?

Ciao, Thorsten
