The code in efi.c uses early_memremap(), but relies on a transitive
include rather than including asm/early_ioremap.h directly, since
this header did not exist on ia64.
Commit f7d9248942 ("arm64/efi: refactor EFI init and runtime code
for reuse by 32-bit ARM") attempted to work around this by including
asm/efi.h, which transitively includes asm/early_ioremap.h on most
architectures. However, since asm/efi.h does not exist on ia64 either,
this is not much of an improvement.
Now that we have created an asm/early_ioremap.h for ia64, we can just
include it directly.

Unlike x86, arm64 and ARM, ia64 does not declare its implementations
of early_ioremap/early_iounmap/early_memremap/early_memunmap in a header
file called <asm/early_ioremap.h>
This complicates the use of these functions in generic code, since the
header cannot be included directly, and we have to rely on transitive
includes, which is fragile.
So create a <asm/early_ioremap.h> for ia64, and move the existing
definitions into it.

drm/i915: Introduce a gmbus power domain
gmbus also needs the power domain infrastructure right from the start,
since as soon as we register the i2c controllers someone can use them.
v2: Adjust cleanup paths too (Chris).
v3: Rebase onto -nightly (totally bogus tree I had lying around) and
also move dpio init head (Ville).
v4: Ville instead suggested to move gmbus setup later in the sequence,
since it's only needed by the modeset code.
v5: Move even close to the actual user, right next to the comment that
states where we really need gmbus (and interrupts!).

Board files that define their own bgpio_pdata are broken when
CONFIG_GPIO_GENERIC is disabled and the bgpio_pdata structure
definition is hidden by the #ifdef:
arch/arm/mach-clps711x/board-autcpu12.c:148:15: error: variable 'autcpu12_mmgpio_pdata' has initializer but incomplete type
static struct bgpio_pdata autcpu12_mmgpio_pdata __initdata = {
arch/arm/mach-clps711x/board-autcpu12.c:149:2: error: unknown field 'base' specified in initializer
.base = AUTCPU12_MMGPIO_BASE,
Since the board files should generally not care what drivers are
enabled, this makes the structure definition visible again.

To the best of our knowledge, everyone who enables audit at compile
time also enables syscall auditing; this patch simplifies the Kconfig
menus by removing the option to disable syscall auditing when audit
is selected and the target arch supports it.

Previously we were emitting seccomp audit records regardless of the
audit_enabled setting, a deparature from the rest of audit. This
patch makes seccomp auditing consistent with the rest of the audit
record generation code in that when audit_enabled=0 nothing is logged
by the audit subsystem.
The bulk of this patch is moving the CONFIG_AUDIT block ahead of the
CONFIG_AUDITSYSCALL block in include/linux/audit.h; the only real
code change was in the audit_seccomp() definition.

An encoder is associated with a connector by the DRM core as a result of
setting up a configuration. Drivers using the atomic or legacy helpers
should never set up this link, even if it is a static one.
While at it, try to catch this kind of error in the future by adding a
WARN_ON() in drm_mode_connector_attach_encoder(). Note that this doesn't
cover all the cases, since drivers could set this up after attaching.
Drivers that use the atomic helpers will get a warning later on, though,
so hopefully the two combined cover enough to help people avoid this in
the future.

The neigh_list with batadv_hardif_neigh_node objects is accessed with only
rcu_read_lock in batadv_hardif_neigh_get and batadv_iv_neigh_print. Thus it
is not allowed to kfree the object before the rcu grace period ends (which
may still protects context accessing this object). Therefore the object has
first to be removed from the neigh_list and then it has either wait with
synchronize_rcu or call_rcu till the grace period ends before it can be
freed.

In commit f309d44431 ("platform_device:
better support builtin boilerplate avoidance") we introduced the
builtin_driver macro.
Here we use that support and extend it to I2C driver registration,
so where a driver is clearly non-modular and builtin-only, we can
register it in a similar fashion. And existing code that is clearly
non-modular can be updated with the simple mapping of
module_i2c_driver(...) ---> builtin_i2c_driver(...)
We've essentially cloned the former to make the latter, and taken
out the remove/module_exit parts since those never get used in a
non-modular build of the code.
A similar thing was done in commit b4eb6cdbbd
("PCI: Add builtin_pci_driver() to avoid registration boilerplate").

In some situations the gpio_list order is not correct.
As a consequence gpiochip_find_base returns the same
base number twice. This happens when a first ship is added
with manual base number, then other ships are added using
automatic base number.
To prevent this behaviour, this patch add the new chip after
the last element of the gpio list.

The vdso-based sigreturn mechanism is fragile and isn't used by
modern glibc so, if we break it, we'll only notice when someone
tests an unusual libc.
Add an explicit selftest.
[ I wrote this while debugging a Bionic breakage -- my first guess
was that I had somehow messed up sigreturn. I've caused problems in
that code before, and it's really easy to fail to notice it because
there's nothing on a modern distro that needs vdso-based sigreturn. ]

Kernel and userspace are able to handle 4GB (1<<32) address space range,
but "A32 Stateless Model" is not. According to documentation, A32 accesses
are based on General State Base Address and bound checking is in place.
Because size field (instruction State Base Address) limitation, it is not
possible to address full 4GB memory region.
A32 Stateless Model is used by some libraries and without this patch, the
last page of 4GB address space is not accessible in 32bit processes.
