A recent series has added CPU numbers to a lot of dts files,

- Since the time we move to MULTI_IRQ_HANDLER, the 0x7f polling for no

polling results in the driver not detecting when irq 0x7f is active

ARM: EXYNOS: uncompress - print debug messages if DEBUG_LL is defined
Printing low-level debug messages make an assumption that the specified
UART port has been preconfigured by the bootloader. Incorrectly
specified UART port results in system getting stalled while printing the
message "Uncompressing Linux... done, booting the kernel"
This UART port number is specified through S3C_LOWLEVEL_UART_PORT. Since
the UART port might different for different board, it is not possible to
specify it correctly for every board that use a common defconfig file.
Calling this print subroutine only when DEBUG_LL fixes the problem. By
disabling DEBUG_LL in default config file, we would be able to boot
multiple boards with different default UART ports.
With this current approach, we miss the print "Uncompressing Linux...
done, booting the kernel." when DEBUG_LL is not defined.

"Here are a few more fixes for powerpc 3.10. It's a bit more than I
would have liked this late in the game but I suppose that's what
happens with a brand new chip generation coming out.
A few regression fixes, some last minute fixes for new P8 features
such as transactional memory,...
There's also one powerpc KVM patch that I requested that adds two
missing functions to our in-kernel interrupt controller support which
is itself a new 3.10 feature. These are defined by the base
hypervisor specification. We didn't implement them originally because
Linux doesn't use them but they are simple and I'm not comfortable
having a half-implemented interface in 3.10 and having to deal with
versionning etc... later when something starts needing those calls.
They cannot be emulated in qemu when using in-kernel interrupt
controller (not enough shared state).
Just added a last minute patch to fix a typo introducing a breakage in
our cputable for Power7+ processors, sorry about that, but the
regression it fixes just hurt me :-)"

powerpc/pseries: Always enable CONFIG_HOTPLUG_CPU on PSERIES SMP
Adam Lackorzynski reported the following build failure on
!CONFIG_HOTPLUG_CPU configuration:
CC arch/powerpc/kernel/rtas.o
arch/powerpc/kernel/rtas.c: In function ‘rtas_cpu_state_change_mask’:
arch/powerpc/kernel/rtas.c:843:4: error: implicit declaration of function ‘cpu_down’ [-Werror=implicit-function-declaration]
cc1: all warnings being treated as errors
make[1]: *** [arch/powerpc/kernel/rtas.o] Error 1
make: *** [arch/powerpc/kernel] Error 2
The build fails because cpu_down() is defined only under CONFIG_HOTPLUG_CPU.
Looking further, the mobility code in pseries is one of the call-sites which
uses rtas_ibm_suspend_me(), which in turn calls rtas_cpu_state_change_mask().
And the mobility code is unconditionally compiled-in (it does not fall under
any Kconfig option). And commit 120496ac (powerpc: Bring all threads online
prior to migration/hibernation) which introduced this build regression is
critical for the proper functioning of the migration code. So it appears
that the only solution to this problem is to enable CONFIG_HOTPLUG_CPU if
SMP is enabled on PPC_PSERIES platforms. So make that change in the Kconfig.

powerpc/kvm/book3s: Add support for H_IPOLL and H_XIRR_X in XICS emulation
This adds the remaining two hypercalls defined by PAPR for manipulating
the XICS interrupt controller, H_IPOLL and H_XIRR_X. H_IPOLL returns
information about the priority and pending interrupts for a virtual
cpu, without changing any state. H_XIRR_X is like H_XIRR in that it
reads and acknowledges the highest-priority pending interrupt, but it
also returns the timestamp (timebase register value) from when the
interrupt was first received by the hypervisor. Currently we just
return the current time, since we don't do any software queueing of
virtual interrupts inside the XICS emulation code.
These hcalls are not currently used by Linux guests, but may be in
future.

While returning from exception handling in case of PREEMPT enabled,
_TIF_NEED_RESCHED bit is checked in TI_FLAGS (thread_info flag) of current
task. Only if this bit is set, it should continue with the process of
calling preempt_schedule_irq() to schedule highest priority task if
available.
Current code assumes that r8 contains TI_FLAGS and check this for
_TIF_NEED_RESCHED, but as r8 is modified in the code which executes before
this check, r8 no longer contains the expected TI_FLAGS information.
As a result check for comparison with _TIF_NEED_RESCHED was failing even if
NEED_RESCHED bit is set in the current thread_info flag. Due to this,
preempt_schedule_irq() and in turn scheduler was not getting called even if
highest priority task is ready for execution.
So, store temporary results in r0 instead of r8 to prevent r8 from getting
modified as subsequent code is dependent on its value.
powerpc/mm: Always invalidate tlb on hpte invalidate and update
If a hash bucket gets full, we "evict" a more/less random entry from it.
When we do that we don't invalidate the TLB (hpte_remove) because we assume
the old translation is still technically "valid". This implies that when
we are invalidating or updating pte, even if HPTE entry is not valid
we should do a tlb invalidate.

powerpc/pseries: Kill all prefetch streams on context switch
On context switch, we should have no prefetch streams leak from one
userspace process to another. This frees up prefetch resources for the
next process.
Based on patch from Milton Miller.

Maynard informed me that neither the oprofile kernel module nor oprofile
userspace has been updated to support that "legacy" oprofile module
interface for power8, which is indicated by "ppc64/power8." This results
in no samples. The solution is to default to the "timer" type, instead.
The raw entry also should be updated, as "ppc64/ibm-compat-v1" indicates
to oprofile userspace to use "compatibility events" which are obsolete
in ISA 2.07.
