2015-08-03ARM: dts: pangolin: Switch led trigger to mmc1Jakob Unterwurzacher
mmc0 and mmc1 have swapped places, mmc0 is the emmc now. Also, let's have better labels.
2015-07-31ARM: sunxi: dts: pangolin: disable 1.2Ghz cpufreqKlaus Goger
disable the 1.2Ghz frequency point so users have to enable it explicity. this should ensure that only boards with installed thermal solutions are used with 1.2Ghz. Note that running on 1.2Ghz will not damage the board as we turn CPU off when overheating. We only want to avoid unexpected shutdowns for users when using the default setup and not mounting the heat sink. Signed-off-by: Klaus Goger <klaus.goger@theobroma-systems.com>

2015-07-30ARM: dts: sun6i: Set PLL6 as parent to AHB1 clock in AHB1 clock nodeChen-Yu Tsai
On sun6i we already have PLL6 as AHB1 clock's parent. However this was previously set in the dma controller node, which takes effect when the dma controller is probed. We want this to take effect as soon as possible, so hrtimer rate calculation is correct, and to be sure the AHB1 clock rate remains as stable as possible.

The cpu core is clocked from the "cpu" clock. Add a reference to it in the first cpu node. Also add "cpu0" label to the node. The operating points were taken from the a list compiled by Maxime Ripard, which is based on A31 FEX files from the sunxi-boards repository. Not all boards have the same settings.

2015-04-10nios2: fix cache coherency issue when debug with gdbLey Foon Tan
Remove the end address checking for flushda function. We need to flush each address line for flushda instruction, from start to end address. This is because flushda instruction only flush the cache if tag and line fields are matched. Change to use ldwio instruction (bypass cache) to load the instruction that causing trap. Our interest is the actual instruction that executed by the processor, this should be uncached. Note, EA address might be an userspace cached address. Signed-off-by: Ley Foon Tan <lftan@altera.com>

2015-04-08x86: clean up/fix 'copy_in_user()' tail zeroingLinus Torvalds
The rule for 'copy_from_user()' is that it zeroes the remaining kernel buffer even when the copy fails halfway, just to make sure that we don't leave uninitialized kernel memory around. Because even if we check for errors, some kernel buffers stay around after thge copy (think page cache). However, the x86-64 logic for user copies uses a copy_user_generic() function for all the cases, that set the "zerorest" flag for any fault on the source buffer. Which meant that it didn't just try to clear the kernel buffer after a failure in copy_from_user(), it also tried to clear the destination user buffer for the "copy_in_user()" case. Not only is that pointless, it also means that the clearing code has to worry about the tail clearing taking page faults for the user buffer case. Which is just stupid, since that case shouldn't happen in the first place. Get rid of the whole "zerorest" thing entirely, and instead just check if the destination is in kernel space or not. And then just use memset() to clear the tail of the kernel buffer if necessary. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2015-04-08Revert "sparc/PCI: Clip bridge windows to fit in upstream windows"Bjorn Helgaas
This reverts commit d63e2e1f3df904bf6bd150bdafb42ddbb3257ea8. David Ahern reported that d63e2e1f3df9 breaks booting on an 8-socket T5 sparc system. He also verified that the system boots with d63e2e1f3df9 reverted. Yinghai has some fixes, but they need a little more polishing than we can do before v4.0.
