[7/9] x86/cpu: Use EXPORT_PER_CPU_SYMBOL_GPL() for x86_spec_ctrl_current

Series x86: Cure tons of sparse warnings (mostly __percpu) | expand

Commit Message

Thomas Gleixner March 4, 2024, 10:12 a.m. UTC 
sparse rightfully complains:

bugs.c:71:9: sparse: warning: incorrect type in initializer (different address spaces)
bugs.c:71:9: sparse:    expected void const [noderef] __percpu *__vpp_verify
bugs.c:71:9: sparse:    got unsigned long long *

The reason is that x86_spec_ctrl_current which is a per CPU variable is
exported with EXPORT_SYMBOL_GPL().

Use EXPORT_PER_CPU_SYMBOL_GPL() instead.
