It was reported that QEMU monitor command gva2gpa was reporting unmapped
memory for a valid access (qemu-system-aarch64), during a copy from
kernel to user space (__arch_copy_to_user symbol in Linux) [1].
This was affecting cpu_memory_rw_debug also, which
is used in numerous places in our codebase. After investigating, the
problem was specific to arm_cpu_get_phys_page_attrs_debug.
When performing user access from a privileged space, we need to do a
second lookup for user mmu idx, following what get_a64_user_mem_index is
doing at translation time.

According to 'man 2 close' errors returned by close() should only be used
for either diagnostic purposes or for catching data loss due to a previous
write error, as an error result of close() usually indicates a deferred
error of a previous write operation.
Therefore not decrementing 'total_open_fd' on a close() error is wrong
and would yield in a higher open file descriptor count than actually the
case, leading to 9p server reclaiming open file descriptors too soon.
