2018-06-01kvm: Make VM ioctl do valloc for some archsMarc Orr1-0/+4
The kvm struct has been bloating. For example, it's tens of kilo-bytes for x86, which turns out to be a large amount of memory to allocate contiguously via kzalloc. Thus, this patch does the following: 1. Uses architecture-specific routines to allocate the kvm struct via vzalloc for x86. 2. Switches arm to __KVM_HAVE_ARCH_VM_ALLOC so that it can use vzalloc when has_vhe() is true. Other architectures continue to default to kalloc, as they have a dependency on kalloc or have a small-enough struct kvm.

2018-06-01kbuild: add machine size to CHECKFLAGSLuc Van Oostenryck1-1/+1
By default, sparse assumes a 64bit machine when compiled on x86-64 and 32bit when compiled on anything else. This can of course create all sort of problems for the other archs, like issuing false warnings ('shift too big (32) for type unsigned long'), or worse, failing to emit legitimate warnings. Fix this by adding the -m32/-m64 flag, depending on CONFIG_64BIT, to CHECKFLAGS in the main Makefile (and so for all archs). Also, remove the now unneeded -m32/-m64 in arch specific Makefiles.

2018-05-30crypto: clarify licensing of OpenSSL asm codeAdam Langley5-8/+46
Several source files have been taken from OpenSSL. In some of them a comment that "permission to use under GPL terms is granted" was included below a contradictory license statement. In several cases, there was no indication that the license of the code was compatible with the GPLv2. This change clarifies the licensing for all of these files. I've confirmed with the author (Andy Polyakov) that a) he has licensed the files with the GPLv2 comment under that license and b) that he's also happy to license the other files under GPLv2 too. In one case, the file is already contained in his CRYPTOGAMS bundle, which has a GPLv2 option, and so no special measures are needed. In all cases, the license status of code has been clarified by making the GPLv2 license prominent. The .S files have been regenerated from the updated .pl files. This is a comment-only change.

We then pass this into the regulator core which has been prepared to hande enable descriptors in a separate patch.

2018-05-29regulator: fixed: Convert to use GPIO descriptor onlyLinus Walleij16-36/+137
As we augmented the regulator core to accept a GPIO descriptor instead of a GPIO number, we can augment the fixed GPIO regulator to look up and pass that descriptor directly from device tree or board GPIO descriptor look up tables. Some boards just auto-enumerate their fixed regulator platform devices and I have assumed they get names like "fixed-regulator.0" but it's pretty hard to guess this. I need some testing from board maintainers to be sure. Other boards are straight forward, using just plain "fixed-regulator" (ID -1) or "fixed-regulator.1" hammering down the device ID. The OMAP didn't have proper label names on its GPIO chips so I have fixed this with a separate patch to the GPIO tree, see commit 088413bc0bd5f5fb66ca22a19d66a49d7154ba4c "gpio: omap: Give unique labels to each GPIO bank/chip" It seems the da9055 and da9211 has never got around to actually passing any enable gpio into its platform data (not the in-tree code anyway) so we can just decide to simply pass a descriptor instead. The fixed GPIO-controlled regulator in mach-pxa/ezx.c was confusingly named "*_dummy_supply_device" while it is a very real device backed by a GPIO line. There is nothing dummy about it at all, so I renamed it with the infix *_regulator_* as part of this patch set. For the patch hunk hitting arch/blackfin I would say I do not expect testing, review or ACKs anymore so if it works, it works. The hunk hitting the x86 BCM43xx driver is especially tricky as the number comes out of SFI which is a mystery to me. I definately need someone to look at this. (Hi Andy.)

2018-05-26ARM: stm32: Don't select DMA unconditionally on STM32MP157CArnd Bergmann1-3/+0
The patch that enabled these had no useful changelog that explains why it is done, and it causes a build warning: WARNING: unmet direct dependencies detected for STM32_DMA Depends on [n]: DMADEVICES [=n] && (ARCH_STM32 [=y] || COMPILE_TEST [=y]) Selected by [y]: - MACH_STM32MP157 [=y] && ARCH_STM32 [=y] && ARCH_MULTI_V7 [=y] Generally, platforms should not select arbitrary drivers, so let's just revert that change.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc Late omap soc changes for v4.18 merge window This series contains two omap1 ams-delta GPIO clean-up patches to get started with removal of hard-coded GPIO numbers from drivers. And then the removal of board mach includes from drivers. The second patch mostly touches the ams-delta audio driver but is included here because of the removal of the latch gpios and is acked by Mark Brown. And there are two more am437x related PM patches to save and restore control module and timer registers for RTC only suspend mode. Looks like the patch title for the timer changes is a bit misleading, not all the timer code is yet living under drivers/clocksource. But I had already pushed out the branch before I noticed this. * tag 'omap-for-v4.18/soc-late-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: OMAP: CLK: CLKSRC: Add suspend resume hooks ARM: AM43XX: Add functions to save/restore am43xx control registers ASoC: ams_delta: use GPIO lookup table ARM: OMAP1: ams-delta: add GPIO lookup tables Signed-off-by: Olof Johansson <olof@lixom.net>
