Add the bit definition and use it in facility_unavailable_exception() so we can

Reserving a runtime region results in splitting the EFI memory

Commit 41c594ab65fc ("[MIPS] MT: Improved multithreading support.")
added an else case to an if statement in do_page_fault() (which has
since gained 2 leading underscores) for some unclear reason. If the
condition in the if statement evaluates true then we execute a goto &
branch elsewhere anyway, so the else has no effect. Combined with an #if
0 block with misleading indentation introduced in the same commit it
makes the code less clear than it could be.
Remove the unnecessary else statement & de-indent the printk within
the #if 0 block in order to make the code easier for humans to parse.

Commit fbde2d7d8290 ("MIPS: Add generic SMP IPI support") introduced a
sanity check that an IPI IRQ domain can be found during boot, in order
to ensure that IPIs are able to be set up in systems using such domains.
However it was added at a point where systems may have used an IPI IRQ
domain in some situations but not others, and we could not know which
were the case until runtime, so commit 578bffc82ec5 ("MIPS: Don't BUG_ON
when no IPI domain is found") made that check simply skip IPI init if no
domain were found in order to fix the boot for systems such as QEMU
Malta.
We now use IPI IRQ domains for the MIPS CPU interrupt controller, which
means systems which make use of IPI IRQ domains will always do so when
running on multiple CPUs. As a result we now strengthen the sanity check
to ensure that an IPI IRQ domain is found when multiple CPUs are present
in the system.

Remove the smp-mt IPI code that supported single-core multithreaded
systems and instead make use of the IPI IRQ domain support provided by
the MIPS CPU interrupt controller driver. This removes some less than
nice code, the horrible split between arch & board code and the
duplication that led to within board code.
The lantiq portion of this patch has only been compile tested. Malta has
been tested & is functional.

Before we rework the "pmem api" to stop abusing __copy_user_nocache()
for memcpy_to_pmem() we need to fix cases where we may strand dirty data
in the cpu cache. The problem occurs when copy_from_iter_pmem() is used
for arbitrary data transfers from userspace. There is no guarantee that
these transfers, performed by dax_iomap_actor(), will have aligned
destinations or aligned transfer lengths. Backstop the usage
__copy_user_nocache() with explicit cache management in these unaligned
cases.
Yes, copy_from_iter_pmem() is now too big for an inline, but addressing
that is saved for a later patch that moves the entirety of the "pmem
api" into the pmem driver directly.

KGDB is a kernel debug stub and it can't be used to debug userland as it
can only safely access kernel memory.
On MIPS however KGDB has always got the register state of sleeping
processes from the userland register context at the beginning of the
kernel stack. This is meaningless for kernel threads (which never enter
userland), and for user threads it prevents the user seeing what it is
doing while in the kernel:
(gdb) info threads
Id Target Id Frame
...
3 Thread 2 (kthreadd) 0x0000000000000000 in ?? ()
2 Thread 1 (init) 0x000000007705c4b4 in ?? ()
1 Thread -2 (shadowCPU0) 0xffffffff8012524c in arch_kgdb_breakpoint () at arch/mips/kernel/kgdb.c:201
Get the register state instead from the (partial) kernel register
context stored in the task's thread_struct for resume() to restore. All
threads now correctly appear to be in context_switch():

The generic_defconfig is used for platforms like SEAD3 which do not
usually have fixed storage available, therefore NFS is the preferred
location of the RFS.
When the upstream kernel defconfig is built & tested on platforms such
as SEAD3 this leads to essentially false failures when the RFS fails to
mount.
There is little harm in having this feature enabled by default, so
enable it in the defconfig. Kernel autoconfiguration & DHCP must also be
selected to allow RFS on NFS.

Under CONFIG_STRICT_DEVMEM, reading System RAM through /dev/mem is
disallowed. However, on x86, the first 1MB was always allowed for BIOS
and similar things, regardless of it actually being System RAM. It was
possible for heap to end up getting allocated in low 1MB RAM, and then
read by things like x86info or dd, which would trip hardened usercopy:
usercopy: kernel memory exposure attempt detected from ffff880000090000 (dma-kmalloc-256) (4096 bytes)
This changes the x86 exception for the low 1MB by reading back zeros for
System RAM areas instead of blindly allowing them. More work is needed to
extend this to mmap, but currently mmap doesn't go through usercopy, so
hardened usercopy won't Oops the kernel.

VCPU TSC synchronization is perfromed in kvm_write_tsc() when the TSC
value being set is within 1 second from the expected, as obtained by
extrapolating of the TSC in already synchronized VCPUs.
This is naturally achieved on all VCPUs at VM start and resume;
however on VCPU hotplug it is not: the newly added VCPU is created
with TSC == 0 while others are well ahead.
To compensate for that, consider host-initiated kvm_write_tsc() with
TSC == 0 a special case requiring synchronization regardless of the
current TSC on other VCPUs.

git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into clk-next
Pull rockchip clk driver updates from Heiko Stuebner:
General rockchip clock changes for 4.12. Contains some new clock-ids
as well as fixups of the clock-ids on rk3368 timers, which were unused
and completely wrong (more and differently named timers).
Also there is one new clock on rk3328 using the muxgrf type, a fix for
pll enablement which should wait for the pll to lock before continuing,
some more critical clocks and the rename of the rk1108 to rv1108, as the
soc seems to have been using a preliminary name before its actual release.
The plan is to have the driver changes (pinctrl, clk) go through the
respective maintainer trees and once everything landed in mainline do
the rename of the devicetree files. With the dts-include change in the
clock rename, we also keep everything compiling and thus bisectability.

Also rework the logic testing for that property so it can be used

NC-SI is used or not in case other variants out there need this.
