If some abnormal users try lots of atomic write operations, f2fs is able to
produce pinned pages in the main memory which affects system performance.
This patch limits that as 20% over total memory size, and if f2fs reaches
to the limit, it will drop all the inmemory pages.

2. add new example for command gzip.
3. fix 2 number errors.
4. fix format of chapter 7.x, make it looks the same as other chapters.

Because Realtek PCIE card reader driver is a pcie driver,
and it bridges mmc subsystem and memstick subsystem, it's
not a mfd driver. Greg and Lee Jones had a discussion about
where to put the driver, the result is that misc is a good
place for it, so I move all files to misc. If I

Add support for new chip rts5260.
In order to support rts5260, the definitions of
some internal registers and workflow have to be
modified and are different from its predecessors
and OCP function is added for RTS5260. So we need
this patch to ensure RTS5260 can work.

Without the patch, when hvs_open_connection() hasn't completely established
a connection (e.g. it has changed sk->sk_state to SS_CONNECTED, but hasn't
inserted the sock into the connected queue), vsock_stream_connect() may see
the sk_state change and return the connection to the userspace, and nex

Remove unnecessary init code, since we would do it in the power_on()
callback.
Also move of parse code to probe().

The driver that instantiates the bridge should own the drvdata, as all
driver model callbacks (probe, remove, shutdown, PM ops, etc.) are also
owned by its driver struct. Moreover, storing two different pointer
types in driver data depending on driver initialization status is barely
a good practice
The rockchip_drm_psr_register() can fail, so add a sanity check for that.
Also reorder the calls in unbind() to match bind().
