2011-10-20hwmon: (w83627ehf) Fix negative 8-bit temperature valuesJean Delvare
Since 8-bit temperature values are now handled in 16-bit struct members, values have to be cast to s8 for negative temperatures to be properly handled. This is broken since kernel version 2.6.39 (commit bce26c58df86599c9570cee83eac58bdaae760e4.)

2011-10-20pinctrl: Don't copy function name when requesting a pinStephen Warren
Instead, store a pointer to the currently assigned function. This allows us to delete the mux_requested variable from pin_desc; a pin is requested if its currently assigned function is non-NULL. When a pin is requested as a GPIO rather than a regular function, the assigned function name is dynamically constructed. In this case, we have to kstrdup() the dynamically constructed name, so that mux_function doesn't pointed at stack data. This requires pin_free to be told whether to free the mux_function pointer or not. This removes the hard-coded maximum function name length.

2011-10-20pinctrl: Don't copy pin names when registering themStephen Warren
A pin controller's names array is no longer marked __refdata. Hence, we can avoid copying a pin's name into the descriptor when registering it. Instead, just point at the string supplied in the pin array. This both simplifies and speeds up pin controller initialization, but also removes the hard-coded maximum pin name length.

2011-10-20pinctrl: Remove unsafe __refdataStephen Warren
A pin controller's pin definitions are used both during pinctrl_register() and pinctrl_unregister(). The latter happens outside of __init/__devinit time, and hence it is unsafe to mark the pin array as __refdata.

2011-10-20pinctrl: get_group_pins() const fixesStephen Warren
get_group_pins() "returns" a pointer to an array of const objects, through a pointer parameter. Fix the prototype so what's pointed at by the returned pointer is const, rather than the function parameter being const. This also allows the removal of a cast in each of the two current pinmux drivers. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2011-10-19stmmac: limit max_mtu in case of 4KiB and use __netdev_alloc_skb (V2)Giuseppe CAVALLARO
Problem using big mtu around 4096 bytes is you end allocating (4096 +NET_SKB_PAD + NET_IP_ALIGN + sizeof(struct skb_shared_info) bytes -> 8192 bytes : order-1 pages It's better to limit the mtu to SKB_MAX_HEAD(NET_SKB_PAD), to have no more than one page per skb. Also the patch changes the netdev_alloc_skb_ip_align() done in init_dma_desc_rings() and uses a variant allowing GFP_KERNEL allocations allowing the driver to load even in case of memory pressure.

2011-10-19stmmac: add CHAINED descriptor mode support (V4)Giuseppe CAVALLARO
This patch enhances the STMMAC driver to support CHAINED mode of descriptor. STMMAC supports DMA descriptor to operate both in dual buffer(RING) and linked-list(CHAINED) mode. In RING mode (default) each descriptor points to two data buffer pointers whereas in CHAINED mode they point to only one data buffer pointer. In CHAINED mode each descriptor will have pointer to next descriptor in the list, hence creating the explicit chaining in the descriptor itself, whereas such explicit chaining is not possible in RING mode. First version of this work has been done by Rayagond. Then the patch has been reworked avoiding ifdef inside the C code. A new header file has been added to define all the functions needed for managing enhanced and normal descriptors. In fact, these have to be specialized according to the ring/chain usage. Two new C files have been also added to implement the helper routines needed to manage: jumbo frames, chain and ring setup (i.e. desc3).

The port shouldn't be enabled unless its current MUX state is DISTRIBUTING which is correctly handled by ad_mux_machine(), otherwise the packet sent can be lost because the other end may not be ready. The issue happens on every port initialization, but as the ports are expected to move quickly to DISTRIBUTING, it doesn't cause much problem. However, it does cause constant packet loss if the other peer has the port configured to stay in STANDBY (i.e. SYNC set to OFF). Signed-off-by: Flavio Leitner <fbl@redhat.com> Signed-off-by: David S.

Due to commit 92fc43b4159b518f5baae57301f26d770b0834c9 ("r8169: modify the flow of the hw reset."), rtl8169_hw_reset stomps during driver shutdown on RxConfig bits which are needed for WOL on some versions of the hardware. As these bits were formerly set from the r81{0x, 68}_pll_power_down methods, factor them out for use in the driver shutdown (rtl_shutdown) handler. I favored __rtl8169_get_wol() -hardware state indication- over RTL_FEATURE_WOL as the latter has become a good candidate for removal.

2011-10-19TTY: serial_core: Fix crash if DCD drop during suspendDoug Anderson
This crash was showing up 100% of the time on Tegra CPUs when an agetty was running on the serial port and the console was not running on the serial port. The reason the Tegra saw it so reliably is that the Tegra CPU internally ties DTR to DCD/DSR. That means when we dropped DTR during suspend we would get always get an immediate DCD drop. The specific order of operations that were running: * uart_suspend_port() would be called to put the uart in suspend mode * we'd drop DTR (ops->set_mctrl(uport, 0)). * the DTR drop would be looped back in the CPU to be a DCD drop. * the DCD drop would look to the serial driver as a hangup * the hangup would call uart_shutdown() * ... suspend / resume happens ... * uart_resume_port() would be called and run the code in the (port->flags & ASYNC_SUSPENDED) block, which would startup the port (and enable tx again). * Since the UART would be available for tx, we'd immediately get an interrupt, eventually calling transmit_chars() * The transmit_chars() function would crash. The first crash would be a dereference of a NULL tty member, but since the port has been shutdown that was just a symptom. I have proposed a patch that would fix the Tegra CPUs here (see https://lkml.org/lkml/2011/10/11/444 - tty/serial: Prevent drop of DCD on suspend for Tegra UARTs). However, even with that fix it is still possible for systems that have an externally visible DCD line to see a crash if the DCD drops at just the right time during suspend: thus this patch is still useful.

2011-10-19phylib: Modify Vitesse RGMII skew settingsAndy Fleming
The Vitesse driver was using the RGMII_ID interface type to determine if skew was necessary. However, we want to move away from using that interface type, as it's really a property of the board's PHY connection. However, some boards depend on it, so we want to support it, while allowing new boards to use the more flexible "fixups" approach. To do this, we extract the code which adds skew into its own function, and call that function when RGMII_ID has been selected. Another side-effect of this change is that if your PHY has skew set already, it doesn't clear it. This way, the fixup code can modify the register without config_init then clearing it.
