This patch makes the mmap call fail outright if the requested region is
larger than the problem state area assigned to the context so the error
is reported immediately rather than waiting for an attempt to access an
address out of bounds.
Although we never expect users to map mo
From: Ian Munsie
It was discovered that if a process mmaped their problem state area they
were able to access one page more than expected, potentially allowing
them to access the problem state area of an unrelated process.
This was due to a simple off by one error in the mmap fault handler
intro
mtmsr() does the right thing on 32bit and 64bit, so use it everywhere.

Shouldn't this be part of patch #1?

Currently the kernel API AFU dev refcounting is done on context start and stop.
This patch moves this refcounting to context init and release, bringing it
inline with how the userspace API does it.
Without this we've seen the refcounting on the AFU get out of whack between the
user and kernel API

For device resource PREF bit setting under bridge 64-bit pref resource,
we need to make sure only set PREF for 64bit resource, so set
IORESOUCE_MEM_64 for 64bit resource during of device resource flags
parsing.

core_idle_state is maintained for each core. It uses 0-7 bits to track
whether a thread in the core has entered fastsleep or winkle. 8th bit is
used as a lock bit.
The lock bit is set in these 2 scenarios-
- The thread is first in subcore to wakeup from sleep/winkle.
- If its the last thread in t

Currently tm_orig_msr is getting used during process context switch only.
Then there is ckpt_regs which saves the checkpointed userspace context
The MSR slot contained in ckpt_regs structure can be used during process
context switch instead of tm_orig_msr, thus allowing us to drop it from

As 'vmx_reserve' array element had been expanded to contain 101 double

the array size declaration to reflect the logic mentioned in the comment
