The binder driver makes the assumption proc->context pointer is invariant after
initialization (as documented in the kerneldoc header for struct proc).
However, in commit f0fe2c0f050d ("binder: prevent UAF for binderfs devices II")
proc->context is set to NULL during binder_deferred_release().
Another proc was in the middle of setting up a transaction to the dying
process and crashed on a NULL pointer deref on "context" which is a local
set to &proc->context:
new_ref->data.desc = (node == context->binder_context_mgr_node) ? 0 : 1;
Here's the stack:

The fix is to move the kfree of the binder_device to binder_free_proc()
so the binder_device is freed when we know there are no references
remaining on the binder_proc.

Currently, geni driver is depending on header inclusion tree for symbol
and prototypes of irq.h. If the dependent header removes the header, geni
driver is failing to compile. To fix the compilation error, include the
header(irq.h) in geni i2c driver.

fault_around aims to reduce minor faults of file-backed pages via
speculative ahead pte mapping and relying on readahead logic. However,
on non-HW access bit architecture the benefit is highly limited because
they should emulate the young bit with minor faults for reclaim's page
aging algorithm. IOW, we cannot reduce minor faults on those
architectures.
I did quick a test on my ARM machine.
512M file mmap sequential every word read on eSATA drive 4 times.
stddev is stable.
= fault_around 4096 =
elapsed time(usec): 6747645
= fault_around 65536 =
elapsed time(usec): 6709263
0.5% gain.
Even when I tested it with eMMC there is no gain because I guess with
slow storage the major fault is the dominant factor.
Also, fault_around has the side effect of shrinking slab more
aggressively and causes higher vmpressure, so if such speculation fails,
it can evict slab more which can result in page I/O (e.g., inode cache).
In the end, it would make void any benefit of fault_around.
So let's make the default "disabled" on those architectures.
