posix_cpu_timers_exit_group() and removes all !CPUCLOCK_PERTHREAD

the fact that the user may have locked the socket. It proceeded

Interrupt-remapping gets enabled very early in the boot, as it determines the
apic mode that the processor can use. And the current code enables the vt-d
fault handling before the setup_local_APIC(). And hence the APIC LDR registers
and data structure in the memory may not be initialized. So the vt-d fault

4.6. Pass gcc-style -m options, instead.
