arm64: kaslr: fix breakage with CONFIG_MODVERSIONS=y

BugLink: http://bugs.launchpad.net/bugs/1633629

As it turns out, the KASLR code breaks CONFIG_MODVERSIONS, since the
kcrctab has an absolute address field that is relocated at runtime
when the kernel offset is randomized.

This has been fixed already for PowerPC in the past, so simply wire up
the existing code dealing with this issue.

net: thunderx: Don't set RX_PACKET_DIS while initializing

BugLink: http://bugs.launchpad.net/bugs/1630038

Setting BGXX_SPUX_MISC_CONTROL::RX_PACKET_DIS is not needed as
packet reception is anyway disabled by BGXX_CMRX_CONFIG::DATA_PKT_RX_EN.
Also setting RX_PACKET_DIS causes a bogus remote fault condition
which delays link detection.

serial: pl011: add console matching function

BugLink: http://bugs.launchpad.net/bugs/1630311

This patch adds function pl011_console_match() that implements
method match of struct console. It allows to match consoles against
data specified in a string, for example taken from command line or
compiled by ACPI SPCR table handler.

UBUNTU: SAUCE: irqchip/gicv3-its: Use MADT ITS subtable to do PCI/MSI domain initialization

BugLink: http://bugs.launchpad.net/bugs/1626631

Let ACPI build ITS PCI MSI domain. ACPI code is responsible for retrieving
inner domain token and passing it on to its_pci_msi_init_one generic
init call.

IORT maintains list of registered domain tokens and allows to find
corresponding domain based on MADT ITS subtable ID info.

UBUNTU: [Config] Switch to compressed Image on arm64

BugLink: http://bugs.launchpad.net/bugs/1384955

Building a 4.8-rc3+ kernel with the current Ubuntu config produces an image
too large for X-Gene/U-Boot systems. The compressed Image is about 1/3 the
size of the uncompressed Image, so switching to that will resolve the issue
with some growing room. And, obviously, it'll save disk space on all arm64
platforms.

UEFI can handle the compressed image just fine. xgene-uboot systems
(Mustang/McDivitt) can as well, as long as the uImage header has
the correct compression flags. Until recently, this was not the case.
uImages were always generated w/ compression=none flag. However, both
flash-kernel and debian-installer in yakkety have recently been updated to
dynamically detect the compression type and set the uImage flag correctly.
After some bake time, I plan to SRU that back into xenial to be ready
for hwe kernels.
