Reading the file will give you a list of masters which can be
selected for a demultiplexed bus. The format is

there is a period where the timer threshold expires with no packets
seen, then an odd behavior is seen as follows:
The first packet arrival after a timer expiry will trigger a timeout
aevent; i.e we dont wait for a timeout period or a packet threshold
event; i.e we don't wait for a timeout period or a packet threshold
to be reached. This is done for simplicity and efficiency reasons.

but also it allows of more flexibility in the handling of devices during the
removal of their drivers.
Drivers in ->remove() callback should undo the runtime PM changes done
in ->probe(). Usually this means calling pm_runtime_disable(),
pm_runtime_dont_use_autosuspend() etc.
The user space can effectively disallow the driver of the device to power manage
it at run time by changing the value of its /sys/devices/.../power/control
attribute to "on", which causes pm_runtime_forbid() to be called. In principle,

"Zone Order" orders the zonelists by zone type, then by node within each
zone. Specify "[Zz]one" for zone order.
Specify "[Dd]efault" to request automatic configuration. Autoconfiguration
will select "node" order in following case.
(1) if the DMA zone does not exist or
(2) if the DMA zone comprises greater than 50% of the available memory or
(3) if any node's DMA zone comprises greater than 70% of its local memory and
the amount of local memory is big enough.
Specify "[Dd]efault" to request automatic configuration.
Otherwise, "zone" order will be selected. Default order is recommended unless
this is causing problems for your system/application.
On 32-bit, the Normal zone needs to be preserved for allocations accessible
by the kernel, so "zone" order will be selected.
On 64-bit, devices that require DMA32/DMA are relatively rare, so "node"
order will be selected.
Default order is recommended unless this is causing problems for your
system/application.

Memory Protection Keys for Userspace (PKU aka PKEYs) is a CPU feature
which will be found on future Intel CPUs.
Memory Protection Keys provides a mechanism for enforcing page-based
protections, but without requiring modification of the page tables
when an application changes protection domains. It works by
dedicating 4 previously ignored bits in each page table entry to a
"protection key", giving 16 possible keys.
There is also a new user-accessible register (PKRU) with two separate
bits (Access Disable and Write Disable) for each key. Being a CPU
register, PKRU is inherently thread-local, potentially giving each
thread a different set of protections from every other thread.
There are two new instructions (RDPKRU/WRPKRU) for reading and writing
to the new register. The feature is only available in 64-bit mode,
even though there is theoretically space in the PAE PTEs. These
permissions are enforced on data access only and have no effect on
instruction fetches.
=========================== Config Option ===========================
This config option adds approximately 1.5kb of text. and 50 bytes of
data to the executable. A workload which does large O_DIRECT reads
of holes in XFS files was run to exercise get_user_pages_fast(). No
performance delta was observed with the config option
enabled or disabled.
