As the code in this file is being executed within irq context in some
cases, we must avoid the clk_get_rate which uses mutex internally.
Switch the code to use clk_hw_get_rate instead which is non-locking.

This fixes an issue where PM runtime will hang the system if enabled
with a serial console before a suspend-resume cycle.

We mis-merged the original patch from Russell here and so the
patch went almost all the way, except that we still failed to
probe when there wasn't a clocks property in the DT node. Allow
that case by making a negative value from
of_clk_get_parent_count() into "no parents", like the original
patch did.

This reverts commit 329cabce.

The commit that caused us to specify LE device endianness here,
29bb45f2 (regmap-mmio: Use native endianness for read/write,
2015-10-29), has been reverted in mainline so now when we specify
LE it actively breaks big endian kernels because the byte
swapping in regmap-mmio is incorrect. Let's revert this change
because it will 1) fix the big endian kernels and 2) be redundant
to specify LE because that will become the default soon.

pll_u can be either controlled by software or hardware and this is
selected via the OVERRIDE bit in the pll_u base register. In the function
tegra210_pll_init(), the OVERRIDE bit for pll_u is cleared, which selects
hardware control of the pll. However, at the same time the pll_u clocks
are populated in the init_table for tegra210 and so software will try to
configure the pll_u if it is not already configured and hence, the above
warning is seen when the pll fails to lock. Remove the pll_u clocks from
the init_table so that software does not try to configure this pll on
boot.

The EMC clock sources for Tegra210 currently incorrectly include pll_c2
and pll_c3. However, both of these should have been pll_mb as shown in
the TRM. If Tegra210 happens to be configured such that the pll_mb is the
default clock for the EMC, as configured by the bootloader, then this will
cause a system hang on boot. This is because the kernel will disable the
pll_mb when disabling unused clock as it appears to be unused when it is
not.

Also add the additional pll_p clock source for the EMC.

Most PLL's don't actually have LOCK_ENABLE bits. However, most PLL's
also had that flag set, which meant that the clk code was trying to
enable locks, and inadvertantly flipping bits in other fields.

For PLLM, ensure the correct register is used for the misc_register.
PLL_MISC0 contains the EN_LCKDET bit which should be used for enabling
the lock, and PLLM_MISC1 shouldn't be used at all.

Lastly, remove some of the settings which would point to the EN_LCKDET
bits for some PLLs. There is no need to enable the locks, and that is
done as part of the set_defaults logic already.

Pull SMB3 fixes from Steve French:
 "A collection of CIFS/SMB3 fixes.

  It includes a couple bug fixes, a few for improved debugging of
  cifs.ko and some improvements to the way cifs does key generation.

  I do have some additional bug fixes I expect in the next week or two
  (to address a problem found by xfstest, and some fixes for SMB3.11
  dialect, and a couple patches that just came in yesterday that I am
  reviewing)"

* 'for-next' of git://git.samba.org/sfrench/cifs-2.6:
  cifs_dbg() outputs an uninitialized buffer in cifs_readdir()
  cifs: fix race between call_async() and reconnect()
  Prepare for encryption support (first part). Add decryption and encryption key generation. Thanks to Metze for helping with this.
  cifs: Allow using O_DIRECT with cache=loose
  cifs: Make echo interval tunable
  cifs: Check uniqueid for SMB2+ and return -ESTALE if necessary
  Print IP address of unresponsive server
  cifs: Ratelimit kernel log messages

Like the Yoga 900 models the Lenovo Yoga 700 does not have a
hw rfkill switch, and trying to read the hw rfkill switch through the
ideapad module causes it to always reported blocking breaking wifi.

This commit adds the Lenovo Yoga 700 to the no_hw_rfkill dmi list, fixing
the wifi breakage.

This patch fixes compile time warnings when CONFIG_PM_SLEEP
is undefined. In this case sleep related counters are unused.

If we detect that there is nothing to do just set the flag and do not
check if it was already set before.  Races really do not matter.  If the
flag is set by any code then the shepherd will start dealing with the
situation and reenable the vmstat workers when necessary again.

Since commit 0eb77e98 ("vmstat: make vmstat_updater deferrable again
and shut down on idle") quiet_vmstat might update cpu_stat_off and mark
a particular cpu to be handled by vmstat_shepherd.  This might trigger a
VM_BUG_ON in vmstat_update because the work item might have been
sleeping during the idle period and see the cpu_stat_off updated after
the wake up.  The VM_BUG_ON is therefore misleading and no more
appropriate.  Moreover it doesn't really suite any protection from real
bugs because vmstat_shepherd will simply reschedule the vmstat_work
anytime it sees a particular cpu set or vmstat_update would do the same
from the worker context directly.  Even when the two would race the
result wouldn't be incorrect as the counters update is fully idempotent.

add a simple bridge to allow re-using this code for zboot.

Add dummy.o to the targets list, and fill targets automatically from
$(vmlinuzobjs) to avoid having to maintain two lists.

When building with XZ compression copy ashldi3.c to the build
directory to use a different object file for the kernel and zboot.
Without this the same object file need to be build with different
flags which cause a rebuild at every run.
