Hi all,
After merging the kvm tree, today's linux-next build (arm64 defconfig)
failed like this:
In file included from <command-line>:
In function 'check_res_bits',
inlined from 'kvm_sys_reg_table_init' at arch/arm64/kvm/sys_regs.c:4109:2:

I bisected this to the merge of the kvm-arm tree into linux-next but I
could not figure out why it fails :-(
