This baseboard from SWAC is equipped with the ICnova-A20 SoM from Incircuit. This board is equipped with the following interfaces / devices: - 512 MiB SDRAM - 4 GiB MLC NAND (Micron MT29F32G08CBACAWP or Hynix H27UBG8T2BTR) - USB host - LCD 800x480 - HDMI - CAN Note that the NAND support is still missing. As its currently not supported in mainline for sunxi and especially for these MLC devices. The original plan was to also provide a dtsi for the ICnova SoM, to put all the SoM internal nodes / properties there. But as I don't have a clear overview of the SoM specific and baseboard specific differences, I'm putting all in one dts for now. Once somebody pushed support for some other baseboard using the A20 SoM from Incircuit (e.g. the ADB4006 reference design), this should be separated.

The PH00 GPIO is wired for headphone plug detection: it reads 0 when nothing's plugged in, and 1 when a plug is inserted. LINEINL/R and FMINL/R are not connected.

mm, page_alloc: distinguish between being unable to sleep, unwilling to sleep and avoiding waking kswapd __GFP_WAIT has been used to identify atomic context in callers that hold spinlocks or are in interrupts. They are expected to be high priority and have access one of two watermarks lower than "min" which can be referred to as the "atomic reserve". __GFP_HIGH users get access to the first lower watermark and can be called the "high priority reserve". Over time, callers had a requirement to not block when fallback options were available. Some have abused __GFP_WAIT leading to a situation where an optimisitic allocation with a fallback option can access atomic reserves. This patch uses __GFP_ATOMIC to identify callers that are truely atomic, cannot sleep and have no alternative. High priority users continue to use __GFP_HIGH. __GFP_DIRECT_RECLAIM identifies callers that can sleep and are willing to enter direct reclaim. __GFP_KSWAPD_RECLAIM to identify callers that want to wake kswapd for background reclaim. __GFP_WAIT is redefined as a caller that is willing to enter direct reclaim and wake kswapd for background reclaim. This patch then converts a number of sites o __GFP_ATOMIC is used by callers that are high priority and have memory pools for those requests. GFP_ATOMIC uses this flag. o Callers that have a limited mempool to guarantee forward progress clear __GFP_DIRECT_RECLAIM but keep __GFP_KSWAPD_RECLAIM. bio allocations fall into this category where kswapd will still be woken but atomic reserves are not used as there is a one-entry mempool to guarantee progress. o Callers that are checking if they are non-blocking should use the helper gfpflags_allow_blocking() where possible. This is because checking for __GFP_WAIT as was done historically now can trigger false positives. Some exceptions like dm-crypt.c exist where the code intent is clearer if __GFP_DIRECT_RECLAIM is used instead of the helper due to flag manipulations. o Callers that built their own GFP flags instead of starting with GFP_KERNEL and friends now also need to specify __GFP_KSWAPD_RECLAIM. The first key hazard to watch out for is callers that removed __GFP_WAIT and was depending on access to atomic reserves for inconspicuous reasons. In some cases it may be appropriate for them to use __GFP_HIGH. The second key hazard is callers that assembled their own combination of GFP flags instead of starting with something like GFP_KERNEL. They may now wish to specify __GFP_KSWAPD_RECLAIM. It's almost certainly harmless if it's missed in most cases as other activity will wake kswapd.

This reverts commit af19161a, which breaks the omap3 device tree build due to a wrong reference. I accidently queued this change via the power supply subsystem while telling Marek at the same time, that it should go through Tony. Following that I did miss Stephen's messages about the build failure in linux-next and since he switched to merging an older snapshot nobody else noticed the problem in my tree. I didn't notice myself, since I did not build any device tree files assuming none have changed by me.

probe_kernel_address() is basically the same as the (later added) probe_kernel_read(). The return value on EFAULT is a bit different: probe_kernel_address() returns number-of-bytes-not-copied whereas probe_kernel_read() returns -EFAULT. All callers have been checked, none cared. probe_kernel_read() can be overridden by the architecture whereas probe_kernel_address() cannot. parisc, blackfin and um do this, to insert additional checking. Hence this patch possibly fixes obscure bugs, although there are only two probe_kernel_address() callsites outside arch/. My first attempt involved removing probe_kernel_address() entirely and converting all callsites to use probe_kernel_read() directly, but that got tiresome. This patch shrinks mm/slab_common.o by 218 bytes. For a single probe_kernel_address() callsite.
