The example code provided with the i2c device interface documentation
won't compile since it uses the reserved word "register" to name a
variable.
The compiler fails with this error message:
error: expected identifier or '(' before '=' token
__u8 register = 0x20; /* Device register to access */
^
Rename the variable "register" to simply "reg" in the example code.
Another couple of typos has been fixed as well.

Most callers of that functions acqure the mutex by themselves and

The update_walltime() code works on the shadow timekeeper to make the
seqcount protected region as short as possible. But that update to the
shadow timekeeper does not update all timekeeper fields because it's
sufficient to do that once before it becomes life. One of these fields
is tkr.base_mono. That stays stale in the shadow timekeeper unless an
operation happens which copies the real timekeeper to the shadow.
The update function is called after the update calls to vsyscall and
pvclock. While not correct, it did not cause any problems because none
of the invoked update functions used base_mono.
commit cbcf2dd3b3 (x86: kvm: Make kvm_get_time_and_clockread()
nanoseconds based) changed that in the kvm pvclock update function, so
the stale mono_base value got used and caused kvm-clock to malfunction.
Put the update where it belongs and fix the issue.

The following series of patches includes fixes to the driver.
- Proper access to 64 bit management counter registers
- Enable all management counter registers to generate an interrupt when
the counter threshold is reached
This patch series is based on net.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
As the management counters reach a threshold they will generate an
interrupt so the value can be saved and the counter reset. The
current code does not enable this interrupt on all counters. This
can result in inaccurate statistics.
Update the code to enable all the counters to generate an interrupt
when its threshold is exceeded.
Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com>
Signed-off-by: David S. Miller <davem@davemloft.net>
Even if the management counters are configured to be 32 bit register
values, the [rt]xoctetcount_gb and [rt]xoctetcount_g counters are
always 64 bit counter registers. Since they are not being treated as
64 bit values, these statistics are being reported incorrectly (ifconfig,
ethtool, etc.).
Update the routines used to read the registers to access the "hi"
register (an offset of 4 from the "lo" register) to create a 64 bit
value for these 64 bit counters.

This patch does not affect the 10/100 GRETH MAC.
Before all GBit GRETH TX descriptor ring cleaning was done in
start_xmit(), when descriptor list became full it activated
TX interrupt to start the NAPI rx poll function to do TX ring
cleaning.
With this patch the TX descriptor ring is always cleaned from
the NAPI rx poll function, triggered via TX or RX interrupt.
Otherwise we could end up in TX frames being sent but not
reported to the stack being sent. On the 10/100 GRETH this
is not an issue since the SKB is copied&aligned into private
buffers so that the SKB can be freed directly on start_xmit()

The reason this is needed is that starting with 3.15 kernel, due to
Theodore Ts'o's commit 02b9984d64 ("fs: push sync_filesystem() down to
the file system's remount_fs()"), all file systems that have dirty data
to be written out need to call sync_filesystem() from their
->remount_fs() method when remounting read-only.
As this is now a generically required function rather than an internal
