make[4]: *** [arch/x86/mm/init_64.o] Error 1
make[4]: *** Waiting for unfinished jobs....

Workaround

add below line in 'build/linux-windriver/linux/include/linux/bootmem.h'

extern void __free_pages_bootmem(struct page *page, unsigned int order);

Steps to Reproduce

1. create a x86 project of RCPL 13: /WindRiver-6.0.0/wrlinux-6/wrlinux/configure --enable-board=intel-x86-64 --enable-kernel=standard --enable-rootfs=glibc-std+initramfs --with-template=feature/initramfs,feature/intel-ras,feature/kexec,feature/kdump --enable-parallel-pkgbuilds=4 --enable-jobs=4 --enable-reconfig --with-rcpl-version=0013

2. build kernel: make -C build linux-windriver
