The exynos random driver uses #ifdef to check for CONFIG_PM, but
then uses SIMPLE_DEV_PM_OPS, which leaves the references out when
CONFIG_PM_SLEEP is not defined, so we get a warning with
PM=y && PM_SLEEP=n:
drivers/char/hw_random/exynos-rng.c:166:12: error: 'exynos_rng_suspend' defined but not used [-Werror=unused-function]
drivers/char/hw_random/exynos-rng.c:171:12: error: 'exynos_rng_resume' defined but not used [-Werror=unused-function]
This removes the incorrect #ifdef and instead uses a __maybe_unused
annotation to let the compiler know it can silently drop
the function definition.

A couple of fields in a data structure, which is used by the driver only,
were not initialized properly during the driver's setup.
The primary issue with this bug was that channel->wr_buf_size remained zero,
so calls to dma_sync_single_for_cpu() took place with zero size, and
consequently did nothing.
This had a rather minimal practical impact, because
(a) these calls are NOPs on Intel/AMD platforms, as well as other platforms
with coherent cache, and
(b) it's extremely rare that any cache line would survive between two reads
from a given DMA buffer
Hence no significant practical difference is expected with this patch.

Commit d07e22597d ("mm: mmap: add new /proc tunable for mmap_base
ASLR") added the ability to choose from a range of values to use for
entropy count in generating the random offset to the mmap_base address.
The maximum value on this range was set to 32 bits for 64-bit x86
systems, but this value could be increased further, requiring more than
the 32 bits of randomness provided by get_random_int(), as is already
possible for arm64. Add a new function: get_random_long() which more
naturally fits with the mmap usage of get_random_int() but operates
exactly the same as get_random_int().
Also, fix the shifting constant in mmap_rnd() to be an unsigned long so
that values greater than 31 bits generate an appropriate mask without
overflow. This is especially important on x86, as its shift instruction
uses a 5-bit mask for the shift operand, which meant that any value for
mmap_rnd_bits over 31 acts as a no-op and effectively disables mmap_base
randomization.
Finally, replace calls to get_random_int() with get_random_long() where
appropriate.
This patch (of 2):
Add get_random_long().

The TPM core has long assumed that every device has a driver attached,
however the force path was attaching the TPM core outside of a driver
context. This isn't generally reliable as the user could detatch the
driver using sysfs or something, but commit b8b2c7d845 ("base/platform:
assert that dev_pm_domain callbacks are called unconditionally")
forced the issue by leaving the driver pointer NULL if there is
no probe.
Rework the TPM setup to create a platform device with resources and
then allow the driver core to naturally bind and probe it through the
normal mechanisms. All this structure is needed anyhow to enable TPM
for OF environments.
Finally, since the entire flow is changing convert the init/exit to use

When doing probing it is important to ensure that other drivers are

This patch define these two ioctl commands to support the 32bit
and 64bit time_t application at the same time. And, introduce
pp_set_timeout to remove some duplicated code.

Drivers should include asm/pci-bridge.h only when they need the arch-
specific things provided there. Outside of the arch/ directories, the only
drivers that actually need things provided by asm/pci-bridge.h are the
powerpc RPA hotplug drivers in drivers/pci/hotplug/rpa*.
Remove the includes of asm/pci-bridge.h from the other drivers, adding an
include of linux/pci.h if necessary.

Merge tag 'for-linus-4.5-2' of git://git.code.sf.net/p/openipmi/linux-ipmi
Pull IPMI fix from Corey Minyard:
"Fix a compile error on IPMI when ACPI is disabled"
* tag 'for-linus-4.5-2' of git://git.code.sf.net/p/openipmi/linux-ipmi:
ipmi: put acpi.h with the other headers
Enclosing '#include <linux/acpi.h>' within '#ifdef CONFIG_ACPI' is
unnecessary, since it has its own conditional compile for CONFIG_ACPI.
Commit 0fbcf4af7c ("ipmi: Convert the IPMI SI ACPI handling to a
platform device") exposed this as a problem for platforms that do not
support ACPI when it introduced a call to ACPI_PTR() macro outside of
the CONFIG_ACPI conditional compile. This would have been perfectly
acceptable if acpi.h were not conditionally excluded for the non-acpi
platform, because the conditional compile within acpi.h defines
ACPI_PTR() to return NULL when compiled for non acpi platforms.
