Binbin Wu 6c05af8ded hv: ptirq : fix a bug in ptirq_release_entry
The mask valuei 0x3F was added to prevent out of range in array access.
However, it should not be hardcoded.
Since in ptirq_alloc_entry_id, the valid allocated id is no greater
than CONFIG_MAX_PT_IRQ_ENTRIES, it will not cause out of range array
access without mask.
So this patch removes the mask.

Also, use bitmap_clear_lock instead of bitmap_clear_nolock becuase there
could be the chance that more than 1 core to access a same 64bit var.

ACRN Hypervisor
###############

The open source `Project ACRN`_ defines a device hypervisor reference stack and
an architecture for running multiple software subsystems, managed securely, on
a consolidated system by means of a virtual machine manager. It also defines a
reference framework implementation for virtual device emulation, called the
"ACRN Device Model".

The ACRN Hypervisor is a Type 1 reference hypervisor stack, running directly on
the bare-metal hardware, and is suitable for a variety of IoT and embedded
device solutions. The ACRN hypervisor addresses the gap that currently exists
between datacenter hypervisors, and hard partitioning hypervisors. The ACRN
hypervisor architecture partitions the system into different functional
domains, with carefully selected guest OS sharing optimizations for IoT and
embedded devices.

You can find out more about Project ACRN on the `Project ACRN documentation`_
website.
