  [IA64] fix "allnoconfig" build

CONFIG_TASKSTATS just had a change to use netlink, including
a change to "depends on NET".  Since "select" does not follow
dependencies, KVM also needs to depend on NET to prevent build
errors when CONFIG_NET is not enabled.

Sample of the reported "undefined reference" build errors:

Kirill Shutemov found problems with the non-upstream IMG driver where the
use of extra DRM encoder/connector types caused random crashes when the DRM
layer tried to display their matching name. This removes the MIPI types
matching the changes Pauli Nieminen made to the non upstream driver set.

As Pauli points out:
" MIPI (or DSI) is protocol specification on top of LVDS serial bus. That
 makes it resonable to call MIPI connectors and encoders LVDS."

(and indeed they may also be HDMI convertors or similar when we want to
 report a more useful to end user result)

Commit b33f9cbd ("regmap: Specify a module license") added a
MODULES_LICENSE to this file without adding an include of module.h.

module.h should have been included anyway, since this file has
EXPORT_SYMBOLs as well.  With the pending module.h split up, this would
probably have caused build problems.

The sparc32 version of arch_write_unlock() is just a plain assignment.
Unfortunately this allows the compiler to schedule side-effects in a
protected region to occur after the HW-level unlock, which is broken.
E.g., the following trivial test case gets miscompiled:

	#include <linux/spinlock.h>
	rwlock_t lock;
	int counter;
	void foo(void) { write_lock(&lock); ++counter; write_unlock(&lock); }

Fixed by adding a compiler memory barrier to arch_write_unlock().  The
sparc64 version combines the barrier and assignment into a single asm(),
and implements the operation as a static inline, so that's what I did too.

Compile-tested with sparc32_defconfig + CONFIG_SMP=y.

The sparc64 spinlock_64.h contains a number of operations defined
first as static inline functions, and then as macros with the same
names and parameters as the functions.  Maybe this was needed at
some point in the past, but now nothing seems to depend on these
macros (checked with a recursive grep looking for ifdefs on these
names).  Other archs don't define these identity-macros.

So this patch deletes these unnecessary macros.

Compile-tested with sparc64_defconfig.

Attempting to try and turn off disconnected display hw in the
hotput handler lead to more problems than it helped.  For
now just register an event and only attempt the do something
interesting with DP.  Other connectors are just too problematic:
- Some systems have an HPD pin assigned to LVDS, but it's rarely
if ever connected properly and we don't really care about hpd
events on LVDS anyway since it's always connected.
- The HPD pin is wired up correctly for eDP, but we don't really
have to do anything since the events since it's always connected.
- Some HPD pins fire more than once when you connect/disconnect
- etc.

The CONFIG_RELOCATABLE code tries to align the unpack destination to
the value of 'kernel_alignment' in the setup_hdr.  If that's 0, it
tries to unpack to address 0, which in fact causes the gunzip code
to call 'error("Out of memory while allocating output buffer")'.

The bootloader (ie. the lguest Launcher in this case) should be doing
setting this field; the normal bzImage is 16M, we can use the same.

Commit db64fe02 ("mm: rewrite vmap layer") introduced code that does
address calculations under the assumption that VMAP_BLOCK_SIZE is a
power of two.  However, this might not be true if CONFIG_NR_CPUS is not
set to a power of two.

Wrong vmap_block index/offset values could lead to memory corruption.
However, this has never been observed in practice (or never been
diagnosed correctly); what caught this was the BUG_ON in vb_alloc() that
checks for inconsistent vmap_block indices.

To fix this, ensure that VMAP_BLOCK_SIZE always is a power of two.
