kbuild: Fix gcc -x syntax

commit b1e0d8b70fa31821ebca3965f2ef8619d7c5e316 upstream.

The correct syntax for gcc -x is "gcc -x assembler", not
"gcc -xassembler". Even though the latter happens to work, the former
is what is documented in the manual page and thus what gcc wrappers
such as icecream do expect.

This isn't a cosmetic change. The missing space prevents icecream from
recognizing compilation tasks it can't handle, leading to silent kernel
miscompilations.

Besides me, credits go to Michael Matz and Dirk Mueller for
investigating the miscompilation issue and tracking it down to this
incorrect -x parameter syntax.

kbuild: make: fix if_changed when command contains backslashes

commit c353acba28fb3fa1fd05fd6b85a9fc7938330f9c upstream.

The call if_changed mechanism does not work when the command contains
backslashes.  This basically is an issue with lzo and bzip2 compressed
kernels.  The compressed binaries do not contain the uncompressed image
size, so these use size_append to append the size.  This results in
backslashes in the executed command.  With this if_changed always
detects a change in the command and rebuilds the compressed image even
if nothing has changed.

Fix this by escaping backslashes in make-cmd

wcnss: Configure WLAN MAC addr through user control interface

wcnss userspace service will use user control interface to configure
certain parameters required by wcnss driver. This interface is required
to configure the WLAN MAC address. These parameter was earlier written
thru module parameters from wcnss service, however that required the
wcnss userspace daemon to have the root permission.

ion: invalidate buffers before zero'ing

Currently, we invalidate the cache for buffers being zero'd *after* we
zero them. However, this is racey since a dirty cache line from an
earlier mapping could be written out to memory between the zero'ing and
the invalidation. Fix this by invalidating the cache *before* zero'ing
the buffer.

Before this change, I was seeing corruption with:

    $ cat <<EOF | ./memory_prof -e -i -
    simple_alloc,1,ION_SYSTEM_HEAP_ID,ION_FLAG_CACHED,0x100000,1MB
    simple_basic_sanity,1
    simple_profile,1
    simple_free,1
    EOF

After this change, no corruption.

msm: kgsl: Refcount mmu clock calls and allow multiple disable events

Allow each mmu clock enable call to enable the clock and let the
clock driver refcounting mechanism deal with switching the clock
off at the right time. This also means that each enable call should
have a disable call or a disable event registered, so allow for
multiple disable events to be registered. This simplifies the mmu
clock handling mechanism which is better for multiple ringbuffer
implementation. With multiple ringbuffers each global timestamp is
tied to a specific ringbuffer and with a single clock disable event
it is hard to figure out when the clock should be turned off.
