2023-06-12xtensa: add asm-prototypes.hMax Filippov
Move assembly source prototypes from xtensa_ksyms.c to asm/asm-prototypes.h, move corresponding EXPORT_SYMBOLs to the assembly sources and enable HAVE_ASM_MODVERSIONS for xtensa. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
2022-12-06xtensa: add __umulsidi3 helperMax Filippov
xtensa gcc-13 has changed multiplication handling and may now use __umulsidi3 helper where it used to use __muldi3. As a result building the kernel with the new gcc may fail with the following error: linux/init/main.c:1287: undefined reference to `__umulsidi3' Fix the build by providing __umulsidi3 implementation for xtensa.
