2017-10-23ARM: dts: imx6sx: Use nvmem-cells for tempmonLeonard Crestez
On imx6sx accessing OCOTP directly is wrong because the ocotp clock needs to be enabled first. Use the nvmem-cells binding instead. This requirement does not apply to older imx6qdl chips because there the ocotp access clock (clk_ipg_s) is always enabled. This is visible by comparing the "System Clocks, Gating, and Override" tables (OCOTP rows) in the 6DQ and 6SX manuals: http://www.nxp.com/assets/documents/data/en/reference-manuals/IMX6SXRM.pdf http://www.nxp.com/assets/documents/data/en/reference-manuals/IMX6DQRM.pdf This happens to work right now because the ocotp clock might be enabled for some other reason. In particular the it might be enabled from the bootloader and it only gets disabled late during boot in clk_disable_unused, after imx-thermal has completed probing. If imx-thermal is compiled as a module then the system can hang on probe.

2017-10-23ARM: dts: imx6ul-14x14-evk: switch lcdif pixel clock to video pllPhilipp Zabel
By default, the lcdif_pre_sel mux is switched to the pll3_pfd1_540m PFD source. If this mux is allowed to propagate rate changes to its parent, setting the LCDIF pixel clock rate to 9 MHz, as required by the LCD panel, will cause the pll3_pfd1_540m PFD to be switched away from its nominal rate to 288 MHz. This has no negative side effects, as there are no other children to this PFD. Still, to avoid surprises, it might be preferrable to switch to the designated video PLL (pll5_video_div) as clock source for the LCDIF pixel clock.

2017-10-22Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/netDavid S. Miller
There were quite a few overlapping sets of changes here. Daniel's bug fix for off-by-ones in the new BPF branch instructions, along with the added allowances for "data_end > ptr + x" forms collided with the metadata additions. Along with those three changes came veritifer test cases, which in their final form I tried to group together properly. If I had just trimmed GIT's conflict tags as-is, this would have split up the meta tests unnecessarily. In the socketmap code, a set of preemption disabling changes overlapped with the rename of bpf_compute_data_end() to bpf_compute_data_pointers(). Changes were made to the mv88e6060.c driver set addr method which got removed in net-next. The hyperv transport socket layer had a locking change in 'net' which overlapped with a change of socket state macro usage in 'net-next'. Signed-off-by: David S. Miller <davem@davemloft.net>

2017-10-22powerpc/perf/hv-24x7: Fix incorrect comparison in memordMichael Ellerman
In the hv-24x7 code there is a function memord() which tries to implement a sort function return -1, 0, 1. However one of the conditions is incorrect, such that it can never be true, because we will have already returned. I don't believe there is a bug in practice though, because the comparisons are an optimisation prior to calling memcmp(). Fix it by swapping the second comparision, so it can be true.

2017-10-22powerpc: Disable the fast-endian switch syscall by defaultMichael Ellerman
Back in 2008 we added support for "fast little-endian switch" in the syscall path. This added a special case syscall number 0x1ebe, which is caught very early in the system call exception and switches endian with as little overhead as possible. See commit 745a14cc264b ("[POWERPC] Add fast little-endian switch system call") for full details. Although it is fast, it's also completely non standard. The "syscall number" is out of the range of normal syscalls, it can't be traced or audited, and it's a bit of a wart. To the best of our knowledge it was only used by one program, now long since discontinued. So in an effort to shake out any current users, put it behind a config option, and make it default n. If anyone *is* using it they can quickly reinstate it with a rebuild, and we can flip it to default y. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
