kvm selftests build fails with below info: rseq_test.c:48:13: error: conflicting types for ‘sys_getcpu’; have ‘void(unsigned int *)’ 48 | static void sys_getcpu(unsigned *cpu) | ^~~~~~~~~~ In file included from rseq_test.c:23: ../rseq/rseq.c:82:12: note: previous definition of ‘sys_getcpu’ with type ‘int(unsigned int *, unsigned int *)’ 82 | static int sys_getcpu(unsigned *cpu, unsigned *node) | ^~~~~~~~~~ commit 66d42ac73fc6 ("KVM: selftests: Make rseq compatible with glibc-2.35") has include "../rseq/rseq.c", and commit 99babd04b250 ("selftests/rseq: Implement rseq numa node id field selftest") add sys_getcpu() implement, so use sys_getcpu in rseq/rseq.c to fix this.
