"Just two changes this time around:
- wire up the new mlock2 syscall added during the last merge window
- fix a build problem with certain configurations provoked by making
CONFIG_OF user selectable"
* 'fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
ARM: 8454/1: OF implies OF_FLATTREE
ARM: wire up mlock2 syscall
On the ARM architecture, individual platforms select CONFIG_USE_OF if they
need it, but all device tree code is keyed off CONFIG_OF. When building
a platform without DT support and manually enabling CONFIG_OF, we now
get a number of build errors, e.g.
arch/arm/kernel/devtree.c: In function 'setup_machine_fdt':
arch/arm/kernel/devtree.c:215:19: error: implicit declaration of function 'early_init_dt_verify' [-Werror=implicit-function-declaration]
We could now try to separate the use case of booting from DT vs. the
case of using the dynamic implementation, but that seems more complicated
than it can gain us.
This simply changes the ARM Kconfig file to always enable OF_RESERVED_MEM
and OF_EARLY_FLATTREE when CONFIG_OF is enabled. These options add a little
extra code when we just want the dynamic OF implementation, but that seems
like a rather obscure case, and this version solves all CONFIG_OF related
randconfig regressions.

Commit b3a72384fe ("ARM/PCI: Replace pci_sys_data->align_resource with
global function pointer") introduced an ARM-specific align_resource()
function pointer. This is not portable to other arches and doesn't work
for platforms with two different PCIe host bridge controllers.
Move the function pointer to the pci_host_bridge structure so each host
bridge driver can specify its own align_resource() function.

OMAP CPU hotplug uses cpu1's clocks and power domains for CPU1 wake up
from low power states (or turn on CPU1). This part of code is also
part of system suspend (disable_nonboot_cpus()).
>From other side, cpu1's clocks and power domains are used by CPUIdle. All above
functionality is mutually exclusive and, therefore, lockless clkdm/pwrdm api
can be used in omap4_boot_secondary().

Since commit 3fffd12839 ("i2c: allow specifying
separate wakeup interrupt in device tree") we have
automatic wakeup irq support for i2c devices. That
commit missed the fact that rtc-1307 had its own
wakeup irq handling and ended up introducing a
kernel splat for at least Beagle x15 boards.
Fix that by reverting original commit _and_ passing
correct interrupt names on DTS so i2c-core can
choose correct IRQ as wakeup.
Now that we have automatic wakeirq support, we can
revert the original commit which did it manually.
Fixes the following warning:

We were setting the physical active state on the GIC distributor in a
preemptible section, which could cause us to set the active state on
different physical CPU from the one we were actually going to run on,
hacoc ensues.
Since we are no longer descheduling/scheduling soft timers in the
flush/sync timer functions, simply moving the timer flush into a
non-preemptible section.

The open coded tests for checking whether a PTE maps a page as
uncached use a flawed '(pte_val(xxx) & CONST) != CONST' pattern,
which is not guaranteed to work since the type of a mapping is
not a set of mutually exclusive bits
For HYP mappings, the type is an index into the MAIR table (i.e, the
index itself does not contain any information whatsoever about the
type of the mapping), and for stage-2 mappings it is a bit field where
normal memory and device types are defined as follows:
#define MT_S2_NORMAL 0xf
#define MT_S2_DEVICE_nGnRE 0x1
I.e., masking *and* comparing with the latter matches on the former,
and we have been getting lucky merely because the S2 device mappings
also have the PTE_UXN bit set, or we would misidentify memory mappings
as device mappings.
Since the unmap_range() code path (which contains one instance of the
flawed test) is used both for HYP mappings and stage-2 mappings, and
considering the difference between the two, it is non-trivial to fix
this by rewriting the tests in place, as it would involve passing
down the type of mapping through all the functions.
However, since HYP mappings and stage-2 mappings both deal with host
physical addresses, we can simply check whether the mapping is backed
by memory that is managed by the host kernel, and only perform the
D-cache maintenance if this is the case.

Currently kernel crash randomly when K2L EVM is booted without
clk_ignore_unused in the bootargs. This workaround is not needed
on other K2 devices such as K2HK and K2E and with this fix, we can
remove the workaround altogether. netcp driver on K2L uses linked
ram on OSR (On chip Static RAM) and requires the clock to this peripheral
enabled for proper functioning. This is the reason for the kernel crash.
So add the clock node to fix this issue.
While at it, remove the workaround documentation as well.
With the fix applied, clk_summary dump shows the clock to OSR enabled.
