Intersil chips ISL29018, ISL29023 and ISL29035 are very similar. They're
all ambience light sensors. The ISL29018, however, is also a proximity
sensor. The registers are similar too:
-------------+----------+----------
AVAILABLE IN | ADDR REG | NAME
290xx | |
-------------+----------+----------
18/23/35| 00h| COMMANDI
18/23/35| 01h| COMMANDII (B4-7 are used only in 29018 for proximity)
18/23/35| 02h| DATALSB
18/23/35| 03h| DATAMSB
18/23/35| 04h| INT_LT_LSB
18/23/35| 05h| INT_LT_MSB
18/23/35| 06h| INT_HT_LSB
18/23/35| 07h| INT_HT_MSB
18/23| 08h| TEST
35| 0Fh| ID
-------------+----------+-----------
So, this patch will add support for ISL29023 and ISL29035 to the
existing isl29018 driver. Since these 2 chips don't have proximity
detection, the proximity sysfs attribute is not needed.
Also, for ISL29035, since it has an ID register, make use of it in order
to properly detect the chip and clear the brownout bit.

Since SCTP day 1, that is, 19b55a2af145 ("Initial commit") from lksctp
tree, the official <netinet/sctp.h> header carries a copy of enum
sctp_sstat_state that looks like (compared to the current in-kernel
enumeration):
User definition: Kernel definition:
enum sctp_sstat_state { typedef enum {
SCTP_EMPTY = 0, <removed>
SCTP_CLOSED = 1, SCTP_STATE_CLOSED = 0,
SCTP_COOKIE_WAIT = 2, SCTP_STATE_COOKIE_WAIT = 1,
SCTP_COOKIE_ECHOED = 3, SCTP_STATE_COOKIE_ECHOED = 2,
SCTP_ESTABLISHED = 4, SCTP_STATE_ESTABLISHED = 3,
SCTP_SHUTDOWN_PENDING = 5, SCTP_STATE_SHUTDOWN_PENDING = 4,
SCTP_SHUTDOWN_SENT = 6, SCTP_STATE_SHUTDOWN_SENT = 5,
SCTP_SHUTDOWN_RECEIVED = 7, SCTP_STATE_SHUTDOWN_RECEIVED = 6,
SCTP_SHUTDOWN_ACK_SENT = 8, SCTP_STATE_SHUTDOWN_ACK_SENT = 7,
}; } sctp_state_t;
This header was later on also placed into the uapi, so that user space
programs can compile without having <netinet/sctp.h>, but the shipped
with <linux/sctp.h> instead.
While RFC6458 under 8.2.1.Association Status (SCTP_STATUS) says that
sstat_state can range from SCTP_CLOSED to SCTP_SHUTDOWN_ACK_SENT, we
nevertheless have a what it appears to be dummy SCTP_EMPTY state from
the very early days.
While it seems to do just nothing, commit 0b8f9e25b0 ("sctp: remove
completely unsed EMPTY state") did the right thing and removed this dead
code. That however, causes an off-by-one when the user asks the SCTP
stack via SCTP_STATUS API and checks for the current socket state thus
yielding possibly undefined behaviour in applications as they expect
the kernel to tell the right thing.
The enumeration had to be changed however as based on the current socket
state, we access a function pointer lookup-table through this. Therefore,
I think the best way to deal with this is just to add a helper function
sctp_assoc_to_state() to encapsulate the off-by-one quirk.

In commit ed98df3361 ("net: use __GFP_NORETRY for high order
allocations") we tried to address one issue caused by order-3
allocations.
We still observe high latencies and system overhead in situations where
compaction is not successful.
Instead of trying order-3, order-2, and order-1, do a single order-3
best effort and immediately fallback to plain order-0.
This mimics slub strategy to fallback to slab min order if the high
order allocation used for performance failed.
Order-3 allocations give a performance boost only if they can be done
without recurring and expensive memory scan.
Quoting David :
The page allocator relies on synchronous (sync light) memory compaction
after direct reclaim for allocations that don't retry and deferred
compaction doesn't work with this strategy because the allocation order
is always decreasing from the previous failed attempt.
This means sync light compaction will always be encountered if memory
cannot be defragmented or reclaimed several times during the
skb_page_frag_refill() iteration.

Enabling DMA_API_DEBUG, warnings are reported at runtime
because the device driver frees DMA memory with wrong functions
and it does not call dma_mapping_error after mapping dma memory.
The first problem is fixed by of introducing a flag that helps us
keeping track which mapping technique was used, so that we can use
the right API for unmap.
This approach was inspired by the e1000 driver, which uses a similar
technique.

The PTP reference clock, used for setting the addend in the Timestamp Addend
Register, was erroneously hard-coded (as reported in the databook just as
example).
The patch removes the macro named: STMMAC_SYSCLOCK and allows to use a
reference clock (clk_ptp_ref_i) that can be passed from the platform.
If not passed, the main driver clock will be used as default; note that
this can be fine on some platforms.
Note that, prior this patch, using the old STMMAC_SYSCLOCK on some platforms,
as side effect, the ptp clock can move faster/slower than the system clock.

This patch is to w/a a problem that happens on some boxes when run at 10Mbps
Half duplex mode.
During the transmission the CSR signal is asserted for some time and the frames
aborted because of carrier sense error.
This is reported by MMC HW counter: txcarrier signal.
This actually is a false carrier so the frames are good and there is no reason
to ask for dropping them.
This patch so disables the Carrier Sense During Transmission
and this means that the MAC transmitter ignore the CRS signal
during frame transmission in Half-Duplex mode.
