Linus Torvalds 08f41f7c35 ARM: SoC fixes
The latest and greatest fixes for ARM platform code. Worth pointing out are:
 
 - Lines-wise, largest is a PXA fix for dealing with interrupts on DT that was
   quite broken. It's still newish code so while we could have held this off,
   it seemed appropriate to include now
 - Some GPIO fixes for OMAP platforms added a few lines. This was also fixes for
   code recently added (this release).
 - Small OMAP timer fix to behave better with partially upstreamed platforms,
   which is quite welcome.
 - Allwinner fixes about operating point control, reducing overclocking in some
   cases for better stability.
 
 + a handful of other smaller fixes across the map.

Without proper regulator support for individual boards, it is dangerous
to have overclocked/overvoltaged OPPs in the list. Cpufreq will increase
the frequency without the accompanying voltage increase, resulting in
an unstable system.

Remove them for now. We can revisit them with the new version of OPP
bindings, which support boost settings and frequency ranges, among
other things.

 "Another few ARM fixes.  Fabrice fixed the L2 cache DT parsing to allow
  prefetch configuration to be specified even when the cache size
  parsing fails.

  Laura noticed that the setting of page attributes wasn't working for
  modules due to is_module_addr() always returning false.

  Marc Gonzalez (aka Mason) noticed a potential latent bug with the way
  we read one of the CPUID registers (where we could attempt to read a
  non-present CPUID register which may fault.)

  I've fixed an issue where 32-bit DMA masks were failing with memory
  which extended to the top of physical address space, and I've also
  added debugging output of the page tables when we hit a data access
  exception which we don't specifically handle - prompted by the lack of
  information in a bug report"

Mark James 1ac31de744 ARM: socfpga: dts: fix spi1 interrupt
The socfpga.dtsi currently has the wrong interrupt number set for SPI master 1
Trying to use the master without this change results in the kernel boot
process waiting forever for an interrupt that will never occur while
attempting to probe any slave devices configured in the device tree as being
under SPI master 1.

The change works for the Cyclone V, and according to the Arria 5 handbook
should be good there too.

Tony Lindgren 599c376c49 ARM: dts: Fix gpio interrupts for dm816x
Commit 7800064ba5 ("ARM: dts: Add basic dm816x device tree
configuration") added basic devices for dm816x, but I was not able
to test the GPIO interrupts earlier until I found some suitable pins
to test with. We can mux the MMC card detect and write protect pins
from SD_SDCD and SD_SDWP mode to use a normal GPIO interrupts that
are also suitable for the MMC subsystem.

This turned out several issues that need to be fixed:

- I set the GPIO type wrong to be compatible with omap3 instead
  of omap4. The GPIO controller on dm816x has EOI interrupt
  register like omap4 and am335x.

- I got the GPIO interrupt numbers wrong as each bank has two
  and we only use one. They need to be set up the same way as
  on am335x.

- The gpio banks are missing interrupt controller related
  properties.

With these changes the GPIO interrupts can be used with the
MMC card detect pin, so let's wire that up. Let's also mux all
the MMC lines for completeness while at it.

For the first GPIO bank I tested using GPMC lines temporarily
muxed to GPIOs on the dip switch 10.

The set_memory_* functions currently only support module
addresses. The addresses are validated using is_module_addr.
That function is special though and relies on internal state
in the module subsystem to work properly. At the time of
module initialization and calling set_memory_*, it's too early
for is_module_addr to work properly so it always returns
false. Rather than be subject to the whims of the module state,
just bounds check against the module virtual address range.

Fabrice Gasnier 5c95ed47f1 ARM: 8310/1: l2c: Fix prefetch settings dt parsing
Allow prefetch settings overriding by device tree, in case
l2x0_cache_size_of_parse() returns value, prefetch tuning
properties are silently ignored. E.g. arm,double-linefill* and
arm,prefetch*.
This happens for example, when "cache-size" or "cache-sets"
properties haven't been filled in l2c dt node.

Comments from Fabrice Gasnier:

 Allow device tree to override the L2C prefetch settings, even when
 l2x0_cache_size_of_parse() fails to parse the cache geometry due to (eg)
 missing "cache-size" or "cache-sets" properties.

The current OMAP dmtimer probe does not check for the return
status of pm_runtime_get_sync() before initializing the timer
registers. Any timer with missing hwmod data would return a
failure here, and the access of registers without enabling the
clocks for the timer would trigger a l3_noc interrupt and a
kernel boot hang. Add proper checking so that the probe would
return a failure graciously without hanging the kernel boot.

This patch adds missing dma DTS definitions for omap aes and sham drivers.
Without it kernel drivers do not work for device tree based booting
while it works for legacy booting on general purpose SoCs.

Note that further changes are still needed for high secure SoCs. But since
that never worked in legacy boot mode either, those will be sent separately.

Linus Torvalds 1ee89c519a The clk fixes for 4.0-rc4 comprise three themes. First are the usual
driver fixes for new regressions since v3.19. Second are fixes to the
 common clock divider type caused by recent changes to how we round clock
 rates. This affects many clock drivers that use this common code.
 Finally there are fixes for drivers that improperly compared struct clk
 pointers (drivers must not deref these pointers). While some of these
 drivers have done this for a long time, this did not cause a problem
 until we started generating unique struct clk pointers for every
 consumer. A new function, clk_is_match was introduced to get these
 drivers working again and they are fixed up to no longer deref the
 pointers themselves.

Shawn Guo a51139fdbc ARM: imx: fix struct clk pointer comparing
Since commit 035a61c314 ("clk: Make clk API return per-user struct clk
instances"), clk API users can no longer check if two struct clk
pointers are pointing to the same hardware clock, i.e. struct clk_hw, by
simply comparing two pointers.  That's because with the per-user clk
change, a brand new struct clk is created whenever clients try to look
up the clock by calling clk_get() or sister functions like clk_get_sys()
and of_clk_get().  This changes the original behavior where the struct
clk is only created for once when clock driver registers the clock to
CCF in the first place.  The net change here is before commit
035a61c314 the struct clk pointer is unique for given hardware
clock, while after the commit the pointers returned by clk lookup calls
become different for the same hardware clock.

That said, the struct clk pointer comparing in the code doesn't work any
more.  Call helper function clk_is_match() instead to fix the problem.

Commit 7ef077a8ad ("usb: isp1760: Move driver from drivers/usb/host/
to drivers/usb/isp1760/") moved the isp1760 driver and changed the
Kconfig option. This makes CONFIG_USB_ISP1760_HCD not selectable
directly anymore. This results in driver being not compiled in when
using vexpress_defconfig and the USB is non-functional.

This patch updates the CONFIG_USB_ISP1760_HCD to CONFIG_USB_ISP1760 to
get back USB functional on vexpress platforms.

Marc Zyngier 04b8dc85bf arm64: KVM: Do not use pgd_index to index stage-2 pgd
The kernel's pgd_index macro is designed to index a normal, page
sized array. KVM is a bit diffferent, as we can use concatenated
pages to have a bigger address space (for example 40bit IPA with
4kB pages gives us an 8kB PGD.

In the above case, the use of pgd_index will always return an index
inside the first 4kB, which makes a guest that has memory above
0x8000000000 rather unhappy, as it spins forever in a page fault,
whist the host happilly corrupts the lower pgd.

The obvious fix is to get our own kvm_pgd_index that does the right
thing(tm).

Tested on X-Gene with a hacked kvmtool that put memory at a stupidly
high address.

Marc Zyngier a987370f8e arm64: KVM: Fix stage-2 PGD allocation to have per-page refcounting
We're using __get_free_pages with to allocate the guest's stage-2
PGD. The standard behaviour of this function is to return a set of
pages where only the head page has a valid refcount.

This behaviour gets us into trouble when we're trying to increment
the refcount on a non-head page:

page:ffff7c00cfb693c0 count:0 mapcount:0 mapping:          (null) index:0x0

CPU0: stopping

A possible approach for this is to split the compound page using
split_page() at allocation time, and change the teardown path to
free one page at a time.  It turns out that alloc_pages_exact() and
free_pages_exact() does exactly that.

While we're at it, the PGD allocation code is reworked to reduce
duplication.

This has been tested on an X-Gene platform with a 4kB/48bit-VA host
kernel, and kvmtool hacked to place memory in the second page of
the hardware PGD (PUD for the host kernel). Also regression-tested
on a Cubietruck (Cortex-A7).

 [ Reworked to use alloc_pages_exact() and free_pages_exact() and to
   return pointers directly instead of by reference as arguments

(so that we can trap 32-bit DMA addresses with >32-bits memory), we had
not taken account of the fact that max_pfn is the maximum PFN number

There are several references in the code which bear this out:

mm/page_owner.c:

	}
