Subject[PATCH v1] ARM: vfp: Use long jump to fix THUMB2 kernel compilation error
Date
The vfp_kmode_exception() function now is unreachable using relative
branching in THUMB2 kernel configuration, resulting in a "relocation
truncated to fit: R_ARM_THM_JUMP19 against symbol `vfp_kmode_exception'"
linker error. Let's use long jump in order to fix the issue.

Fixes: eff8728fe698 ("vmlinux.lds.h: Add PGO and AutoFDO input sections")
