commit 268a1 "regulator: twl-regulator: Use DIV_ROUND_UP at appropriate places" introduced an off-by-one bug for setting vsel. The linear calculation code in twl6030smps_list_voltage() does subtract index by 1 so we need the vsel++ after DIV_ROUND_UP. The original code use this trick to differentiate if we are going to set the voltage to 0 or the voltage falls within the linear calculation range.

This patch makes the code easier to read. Also add checking the case when no desc id is matched. This is required because if no desc id is matched, the poiner info is pointed to twl_of_match[i].data which may be not NULL. Checking info is NULL or not latter does not catch the error.

The n_bits is only used in max8997_get_voltage_proper_val to check the valid range for variable i. Current code already ensures min_vol never greater than desc->max, which means the variable i always in the valid range: 0 .. (desc->max - desc->min)/desc->step. Thus we can remove the checking (i >= (1 << desc->n_bits) and then remove n_bits from struct voltage_map_desc.

s5m8767_set_voltage not only implement set_voltage callbacks for LDOs, but also for BUCKs when s5m8767->buck_gpioindex is not set. s5m8767_set_voltage_buck actually only for buck[2|3|4] when s5m8767->buck_gpioindex is set. Conditionally calling s5m8767_set_voltage in s5m8767_set_voltage_buck makes the code hard to read. I think merging s5m8767_set_voltage_buck and s5m8767_set_voltage actually simplifies things. It's easy to use buck234_vol pointer to differentiate if we need to control voltage for buck[2|3|4] by DVS GPIOs. This patch reworks s5m8767_set_voltage to support both LDOx and BUCKx in all cases.

Rather than adding new arguments to regulator_register() every time we want to add a new bit of dynamic information at runtime change the function to take these via a struct. By doing this we avoid needing to do further changes like the recent addition of device tree support which required each regulator driver to be updated to take an additional parameter. The regulator_desc which should (mostly) be static data is still passed separately as most drivers are able to configure this statically at build time.

Add abort flag and use it to terminate processing when an exchange is timed out or is reset. The abort flag is used in place of the transport_generic_free_cmd function call in the reset and timeout cases, because calling that function in that context would free memory that was in use. The aborted flag allows the lifetime to be managed in a more normal way, while truncating the processing. This change eliminates a source of memory corruption which manifested in a variety of ugly ways.

I have a new optimized x86 "strncpy_from_user()" that will use these same helper functions for all the same reasons the name lookup code uses them. This is preparation for that. This moves them into an architecture-specific header file. It's architecture-specific for two reasons: - some of the functions are likely to want architecture-specific implementations. Even if the current code happens to be "generic" in the sense that it should work on any little-endian machine, it's likely that the "multiply by a big constant and shift" implementation is less than optimal for an architecture that has a guaranteed fast bit count instruction, for example. - I expect that if architectures like sparc want to start playing around with this, we'll need to abstract out a few more details (in particular the actual unaligned accesses). So we're likely to have more architecture-specific stuff if non-x86 architectures start using this. (and if it turns out that non-x86 architectures don't start using this, then having it in an architecture-specific header is still the right thing to do, of course) Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Fix from Eric Dumazet. 11) do_tcp_sendpage() unloads the send queue way too fast, because it invokes tcp_push() when it shouldn't. Let the natural sequence generated by the splice paths, and the assosciated MSG_MORE settings, guide the tcp_push() calls. Otherwise what goes out of TCP is spaghetti and doesn't batch effectively into GSO/TSO clusters. From Eric Dumazet. 12) Once we put a SKB into either the netlink receiver's queue or a socket error queue, it can be consumed and freed up, therefore we cannot touch it after queueing it like that. Fixes from Eric Dumazet. 13) PPP has this annoying behavior in that for every transmit call it immediately stops the TX queue, then calls down into the next layer to transmit the PPP frame. But if that next layer can take it immediately, it just un-stops the TX queue right before returning from the transmit method. Besides being useless work, it makes several facilities unusable, in particular things like the equalizers. Well behaved devices should only stop the TX queue when they really are full, and in PPP's case when it gets backlogged to the downstream device. David Woodhouse therefore fixed PPP to not stop the TX queue until it's downstream can't take data any more. 14) IFF_UNICAST_FLT got accidently lost in some recent stmmac driver changes, re-add.

Not every regulator driver should implement set_voltage_sel callback. See commit e8eef82b "regulator: Provide a selector based set_voltage_sel() operation". For rc5t583, the regulator voltage can be mapped onto selector values with a simple calculation, thus implement set_voltage is better than set_voltage_sel.
