git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc updates from Michael Ellerman: "Highlights include: - Support for the kexec_file_load() syscall, which is a prereq for secure and trusted boot. - Prevent kernel execution of userspace on P9 Radix (similar to SMEP/PXN). - Sort the exception tables at build time, to save time at boot, and store them as relative offsets to save space in the kernel image & memory. - Allow building the kernel with thin archives, which should allow us to build an allyesconfig once some other fixes land. - Build fixes to allow us to correctly rebuild when changing the kernel endian from big to little or vice versa. - Plumbing so that we can avoid doing a full mm TLB flush on P9 Radix. - Initial stack protector support (-fstack-protector). - Support for dumping the radix (aka. Linux) and hash page tables via debugfs. - Fix an oops in cxl coredump generation when cxl_get_fd() is used. - Freescale updates from Scott: "Highlights include 8xx hugepage support, qbman fixes/cleanup, device tree updates, and some misc cleanup." - Many and varied fixes and minor enhancements as always.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This is a fairly quiet release. We don't have any patches to the core framework. The only patch that can even be considered "core" adds another clk_get() variant. The rest of the changes are in drivers for various SoCs, and we have a few bits for ARM shmobile architecture code (dts and mach) due to the dependency we're breaking between shmobile architecture code and its clk driver. Those shmobile bits have also been pulled into arm-soc tree.

We get the following warning with the driver is compiled in: WARNING: modpost: Found 1 section mismatch(es). To see full details build your kernel with: 'make CONFIG_DEBUG_SECTION_MISMATCH=y' With CONFIG_DEBUG_SECTION_MISMATCH enabled, the details are reported: WARNING: vmlinux.o(.text+0x55d014): Section mismatch in reference from the function fsl_guts_probe() to the function .init.text:of_flat_dt_get_machine_name() The function fsl_guts_probe() references the function __init of_flat_dt_get_machine_name(). This is often because fsl_guts_probe lacks a __init annotation or the annotation of of_flat_dt_get_machine_name is wrong.

2016-11-15soc/tegra: pmc: Use consistent naming for PM domainsThierry Reding
The various error messages refer to the PM domains as "power domain", "genpd" and "PM domain". That's confusing, so convert all error messages to use the most prominent: "PM domain". Acked-by: Jon Hunter <jonathanh@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
2016-11-15soc/tegra: pmc: Remove genpd when adding provider failsJon Hunter
Commit 3fe577107ccf ("PM / Domains: Add support for removing PM domains") add support for removing PM domains. Update the Tegra PMC driver to remove PM domains if we fail to add a provider for the PM domain. Please note that the code under 'power_on_cleanup' label does not really belong in the clean-up error path for tegra_powergate_add(). To keep the error path simple, remove this label and move the associated code to where it needs to be invoked.

2016-11-15soc/tegra: pmc: Simplify IO rail bit handlingJon Hunter
The function tegra_io_rail_prepare() converts the IO rail ID into a bit position that is used to check the status and control the IO rail in the PMC registers. However, rather than converting to a bit position it is more useful to convert to a bit-mask because this is what is actually used. By doing so the BIT() marco only needs to be used once and we can use the IO_DPD_REQ_CODE_MASK when checking for erroneous rail IDs.

2016-11-15soc/tegra: pmc: Guard against uninitialised PMC clockJon Hunter
It is possible for the public functions, tegra_io_rail_power_on/off() to be called before the PMC device has been probed. If this happens then the pmc->clk member will not be initialised and the call to clk_get_rate() in tegra_io_rail_prepare() will return zero and lead to a divide-by-zero exception. The function clk_get_rate() will return zero if a NULl clk pointer is passed. Therefore, rather that checking if pmc->clk is initialised, fix this by checking the return value for clk_get_rate() to make sure it is not zero.

2016-11-15soc/tegra: pmc: Add I/O pad voltage supportLaxman Dewangan
I/O pins on Tegra SoCs are grouped into so-called I/O pads. Each such pad can be used to control the common voltage signal level and power state of the pins in the given pad. I/O pads can be powered down even if the system is active, which can save power from that I/O interface. For SoC generations prior to Tegra124 the I/O pad voltage is automatically detected and hence the system software doesn't need to configure it. However, starting with Tegra210 the detection logic has been removed, so explicit control of the I/O pad voltage by system software is required.
