Dan Carpenter a69ede709f xen/acpi: off by one in read_acpi_id() ...

[ Upstream commit c37a3c9477 ]

If acpi_id is == nr_acpi_bits, then we access one element beyond the end
of the acpi_psd[] array or we set one bit beyond the end of the bit map
when we do __set_bit(acpi_id, acpi_id_present);

Fixes: 59a5680291 ("xen/acpi-processor: C and P-state driver that uploads said data to hypervisor.")
