Designing Cards and Drivers for the Macintosh Family, 3rd ed. on page 310
says that the I/O address space for the Mac LC is $50F0 0000 - $50FF FFFF.
The developer notes for the Classic II, LC III and IIvx/IIvi give the same
I/O address space.
That means I've assigned the wrong platform resources to those Mac models.
Fix the scsi_type initialization for the affected models, to restore the
SCSI base address to its value prior to Linux 3.18.
Also rename MAC_SCSI_CCL as MAC_SCSI_LC for the sake of correct chronology.

The rtc.o is built for obj-y, i.e. always built in. It will
never be modular, so using module_init as an alias for __initcall
can be somewhat misleading.
Fix this up now, so that we can relocate module_init from
init.h into module.h in the future. If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.
Note that direct use of __initcall is discouraged, vs. one
of the priority categorized subgroups. As __initcall gets
mapped onto device_initcall, our use of device_initcall
directly in this change means that the runtime impact is
zero -- it will remain at level 6 in initcall ordering.

dmesg (from util-linux) currently has two methods for reading the kernel
message ring buffer: /dev/kmsg and syslog(2). Since kernel 3.5.0 kmsg
has been the default, which escapes control characters (e.g. new lines)
before they are shown.
This change means that when dmesg is using /dev/kmsg, a 2 line printk
makes the output messy, because the second line does not get a
timestamp.
For example:
[ 0.012863] CPU0: Thermal monitoring enabled (TM1)
[ 0.012869] Last level iTLB entries: 4KB 1024, 2MB 1024, 4MB 1024
Last level dTLB entries: 4KB 1024, 2MB 1024, 4MB 1024, 1GB 4
[ 0.012958] Freeing SMP alternatives memory: 28K (ffffffff81d86000 - ffffffff81d8d000)
[ 0.014961] dmar: Host address width 39
Because printk.c intentionally escapes control characters, they should
not be there in the first place. This patch fixes two occurrences of
this.

This SoC belongs to the Armada 38x family. The main difference with
the Armada 385 is that the 388 can handle two more SATA
ports. Currently the consequence is the use of a different compatible
string for the pinctrl node, in order to be able to use the pins
associated to this 2 new SATA ports. The second SATA controller has
also been moved from the armada38x.dtsi as it it specific to the
Armada388 version.
In the same time the Armada385 DB and Armada 385 RD board have been
renamed in the 388 one and now include the armada-388.dtsi file. AS
both of them have 4 SATA ports the SoC used on them were wrongly

If a page-fault is detected in this phase, the error-code which would be
delivered to the VM does not indicate that the access that caused the exception
is a write one. This does not conform with real hardware, and may cause the VM

- Fix ACPI power management intialization for device objects
corresponding to devices that are not present at the init time
(the _STA control method returns 0 for them) and therefore should
not be regarded as power manageable (Rafael J Wysocki).
- Rename a structure field and two functions used by the ACPI
processor driver to make them less tied to architectures that
use APICs (both x86 and ia64) and more suitable for ARM64
processors (Hanjun Guo).
- Add a disable_native_backlight quirk for Dell XPS15 L521X
designed in an unusual way preventing native backlight from
working on that machine (Hans de Goede).

Pull power management and ACPI fixes from Rafael Wysocki:
"These are an ACPI device power management initialization fix (-stable
material), two commits renaming stuff in the ACPI processor driver to
make it more suitable for ARM64 processors and a new ACPI backlight
blacklist entry.
Specifics:
- Fix ACPI power management intialization for device objects
corresponding to devices that are not present at the init time (the
_STA control method returns 0 for them) and therefore should not be
regarded as power manageable (Rafael J Wysocki).
- Rename a structure field and two functions used by the ACPI
processor driver to make them less tied to architectures that use
APICs (both x86 and ia64) and more suitable for ARM64 processors
(Hanjun Guo).
- Add a disable_native_backlight quirk for Dell XPS15 L521X designed

ACPI / video: Add disable_native_backlight quirk for Dell XPS15 L521X
ACPI / processor: Rename acpi_(un)map_lsapic() to acpi_(un)map_cpu()
ACPI / processor: Convert apic_id to phys_id to make it arch agnostic
ACPI / PM: Fix PM initialization for devices that are not present
Adds a function kvm_vcpu_set_pending_timer instead of calling
kvm_make_request in lapic.c.

When access to descriptor in LDT/GDT wraparound outside long-mode, the address
of the descriptor should be truncated to 32-bit. Citing Intel SDM 2.1.1.1
"Global and Local Descriptor Tables in IA-32e Mode": "GDTR and LDTR registers
are expanded to 64-bits wide in both IA-32e sub-modes (64-bit mode and
compatibility mode)."
So in other cases, we need to truncate. Creating new function to return a
pointer to descriptor table to avoid too much code duplication.
