Per Bilse 415dab3c17 drivers/xen/hypervisor: Expose Xen SIF flags to userspace ... /proc/xen is a legacy pseudo filesystem which predates Xen support getting merged into Linux. It has largely been replaced with more normal locations for data (/sys/hypervisor/ for info, /dev/xen/ for user devices). We want to compile xenfs support out of the dom0 kernel. There is one item which only exists in /proc/xen, namely /proc/xen/capabilities with "control_d" being the signal of "you're in the control domain". This ultimately comes from the SIF flags provided at VM start. This patch exposes all SIF flags in /sys/hypervisor/start_flags/ as boolean files, one for each bit, returning '1' if set, '0' otherwise. Two known flags, 'privileged' and 'initdomain', are explicitly named, and all remaining flags can be accessed via generically named files, as suggested by Andrew Cooper.
