In the current implementation handles hold references to a

result when a process terminates it's handles can't be cleaned
up and we leak memory. Instead only hold references to handles
from clients.

In LP1 suspend, or during a failed LP0 suspend, the core power is

remove areas of memory from the 1:1 mapping, allowing them to be

tegra_reserve should be called from the machine reserve callback
after any board-specific memory areas are reserved.

virtio: console: Don't block entire guest if host doesn't read data
If the host is slow in reading data or doesn't read data at all,
blocking write calls not only blocked the program that called write()
but the entire guest itself.
To overcome this, let's not block till the host signals it has given
back the virtio ring element we passed it. Instead, send the buffer to
the host and return to userspace. This operation then becomes similar
to how non-blocking writes work, so let's use the existing code for this
path as well.
This code change also ensures blocking write calls do get blocked if
there's not enough room in the virtio ring as well as they don't return
-EAGAIN to userspace.
