Commits 925f5532 (xtensa: ccount based clockevent implementation) and e3f43291
(xtensa: ccount based sched_clock) introduced users of ccount_freq. This
variable doesn't exist when CONFIG_XTENSA_CALIBRATE_CCOUNT is disabled. Add
ccount_freq definition in this case.

-e is not needed to output strings without escape sequences. This breaks
big endian FSF build when the shell is dash, because its builtin echo
doesn't understand '-e' switch and outputs it in the echoed string.

Check pending signals and rescheduling thread flags with interrupts
disabled, and don't enable them if no flags are set. Call
trace_hardirqs_on after thread flags handling, so that rescheduling is
done and hardirqs tracking flag is updated in the correct task context.

Conflicts:
drivers/net/ethernet/stmicro/stmmac/stmmac_platform.c
net/bridge/br_multicast.c
net/ipv6/sit.c
The conflicts were minor:
1) sit.c changes overlap with change to ip_tunnel_xmit() signature.
2) br_multicast.c had an overlap between computing max_delay using
msecs_to_jiffies and turning MLDV2_MRC() into an inline function
with a name using lowercase instead of uppercase letters.
3) stmmac had two overlapping changes, one which conditionally allocated
and hooked up a dma_cfg based upon the presence of the pbl OF property,
and another one handling store-and-forward DMA made. The latter of
which should not go into the new of_find_property() basic block.

Fixed compilation errors in case of non-KEXEC kernel
Rearranging code so that crashk_res gets updated.
- crashk_res is updated after mips_parse_crashkernel(),
after resource_init(), which is after arch_mem_init().
- The reserved memory is actually treated as Usable memory,
Unless we load the crash kernel, everything works.

This change corrects DECstation HRT calibration, by removing the following
bugs:
1. Calibration period selection -- HZ / 10 has been chosen, however on
DECstation computers, HZ never divides by 10, as the choice for HZ is
among 128, 256 and 1024. The choice therefore results in a systematic
calibration error, e.g. 6.25% for the usual choice of 128 for HZ:
128 / 10 * 10 = 120
(128 - 120) / 128 -> 6.25%
The change therefore makes calibration use HZ / 8 that is always
accurate for the HZ values available, getting rid of the systematic
error.
2. Calibration starting point synchronisation -- the duration of a number
of intervals between DS1287A periodic interrupt assertions is measured,
however code does not ensure at the beginning that the interrupt has
not been previously asserted. This results in a variable error of e.g.
up to another 6.25% for the period of HZ / 8 (8.(3)% with the original
HZ / 10 period) and the usual choice of 128 for HZ:
1 / 16 -> 6.25%
1 / 12 -> 8.(3)%
The change therefore adds an initial call to ds1287_timer_state that
clears any previous periodic interrupt pending.
The same issue applies to both I/O ASIC counter and R4k CP0 timer
calibration on DECstation systems as similar code is used in both cases
and both pieces of code are covered by this fix.
On an R3400 test system used this fix results in a change of the I/O ASIC
clock frequency reported from values like:
I/O ASIC clock frequency 23185830Hz
to:
I/O ASIC clock frequency 24999288Hz
removing the miscalculation by 6.25% from the systematic error and (for
the individual sample provided) a further 1.00% from the variable error,
accordingly. The nominal I/O ASIC clock frequency is 25MHz on this
system.
Here's another result, with the fix applied, from a system that has both
HRTs available (using an R4400 at 60MHz nominal):
MIPS counter frequency 59999328Hz
I/O ASIC clock frequency 24999432Hz

Early microcode loading runs C code before paging is enabled on 32
bits. Since ftrace puts a hook into every function, that hook needs
to be safe to execute in the pre-paging environment. This is
currently true for dynamic ftrace but not for static ftrace.
Static ftrace is obsolescent and assumed to not be
performance-critical, so we can simply test that the stack pointer
falls within the valid range of kernel addresses.

Commit 24ec2125f3 ("powerpc/xmon: Use cpumask iterator to avoid warning")
replaced a loop from 0 to NR_CPUS-1 with a for_each_possible_cpu() loop,
which means that if the last possible cpu is in xmon, we print the
wrong value for the end of the range. For example, if 4 cpus are
possible, NR_CPUS is 128, and all cpus are in xmon, we print "0-7f"
rather than "0-3". The code also assumes that the set of possible
cpus is contiguous, which may not necessarily be true.
This fixes the code to check explicitly for contiguity, and to print
the ending value correctly.

Cast usecs to u64, to ensure that the (usecs * 4295 * HZ)
multiplication is 64 bit.
Initially, the (usecs * 4295 * HZ) part was done as a 32 bit
multiplication, with the result casted to 64 bit. This led to some bits
falling off, causing a "DMA initialization error" in the stmmac Ethernet
driver, due to a premature timeout.

Pull Xen updates from Konrad Rzeszutek Wilk:
"A couple of features and a ton of bug-fixes. There is also some
maintership changes. Jeremy is enjoying the full-time work at the
startup and as much as he would love to help - he can't find the time.
I have a bunch of other things that I promised to work on - paravirt
diet, get SWIOTLB working everywhere, etc, but haven't been able to
find the time.
As such both David Vrabel and Boris Ostrovsky have graciously
volunteered to help with the maintership role. They will keep the lid
on regressions, bug-fixes, etc. I will be in the background to help -
but eventually there will be less of me doing the Xen GIT pulls and
more of them. Stefano is still doing the ARM/ARM64 and will continue
on doing so.
Features:
- Xen Trusted Platform Module (TPM) frontend driver - with the
backend in MiniOS.
- Scalability improvements in event channel.
- Two extra Xen co-maintainers (David, Boris) and one going away (Jeremy)
Bug-fixes:
- Make the 1:1 mapping work during early bootup on selective regions.
- Add scratch page to balloon driver to deal with unexpected code
still holding on stale pages.
- Allow NMIs on PV guests (64-bit only)
- Remove unnecessary TLB flush in M2P code.
- Fixes duplicate callbacks in Xen granttable code.
- Fixes in PRIVCMD_MMAPBATCH ioctls to allow retries
- Fix for events being lost due to rescheduling on different VCPUs.
- More documentation"

Pull pin control changes from Linus Walleij:
"Here is the bulk of pin control changes for the v3.12 series. Most of
the relevant information is in the tag.
I merged in v3.11-rc7 last week to get rid of a largeish conflict
within the sunxi (AllWinner) driver in linux-next and fix up the
non-trivial merge the right way. That driver had a rather large fix
adding locking late in the release cycle.
Overall the bulk changes this time is cleanups and refactorings and
not much new features, which is nice.
- Refactorings for generic pin config handling in the core.
- Factor out a set of device tree utilities for use in all drivers,
to parse and allocate maps from the device tree.
- Some fixes to the core such as more nitpicky locking.
- Pushed down config array iteration into the drivers.
This patch is necessary for drivers that want to iterate over
configs and pile up a stack of alterations to the same register(s),
or if the driver wants to take a local spinlock when committing the
configuration.
- A new driver for the Texas Instruments Palmas PMIC by Laxman
Dewangan. This is used on the Tegra systems.
- A major cleanup and modernization of the PFC (Super Hitachi and ARM
SHmobile) pin controller and subdrivers.
- Support for the A20 and A31 sunxi (AllWinner) SoCs.
- A huge pile of fixes and cleanups: Axel Lin, Jingoo Han Dan
Carpenter, Julia Lawall and Sachin Kamat did an excellent job here"

The SMAP register offsets in the versatile PCI controller code were
all off by four. (This didn't have any observable bad effects
because on this board PHYS_OFFSET is zero, and (a) writing zero to
the flags register at offset 0x10 has no effect and (b) the reset
value of the SMAP register is zero anyway, so failing to write SMAP2
didn't matter.)

The versatile PCI controller code was confused between the
PCI I/O window (at 0x43000000) and the first PCI memory
window (at 0x44000000). Pass the correct base address to
pci_remap_io() so that PCI I/O accesses work.
Since the first PCI memory window isn't used at all (it's
an odd size), rename the associated variables and labels
so that it's clear that it isn't related to the I/O window.
This has been tested and confirmed to fix PCI I/O accesses
both on physical PB926+PCI backplane hardware and on QEMU.

The PCI controller code for the Versatile board has never had the
correct IRQ mapping for hardware. For many years it had an odd
mapping ("all interrupts are int 27") which aligned with the
equivalent bug in QEMU. However as of commit 1bc39ac5dab265
the mapping changed and no longer matched either hardware or QEMU,
with the result that any PCI card beyond the first in QEMU would
not have functioning interrupts; for example a boot with a SCSI
controller would time out as follows:
------------
sym0: <895a> rev 0x0 at pci 0000:00:0d.0 irq 92
sym0: SCSI BUS has been reset.
scsi0 : sym-2.2.3
[...]
scsi 0:0:0:0: ABORT operation started
scsi 0:0:0:0: ABORT operation timed-out.
scsi 0:0:0:0: DEVICE RESET operation started
scsi 0:0:0:0: DEVICE RESET operation timed-out.
scsi 0:0:0:0: BUS RESET operation started
scsi 0:0:0:0: BUS RESET operation timed-out.
scsi 0:0:0:0: HOST RESET operation started
sym0: SCSI BUS has been reset
------------
Fix the mapping so that it matches real hardware (checked against the
schematics for PB926 and backplane, and tested against the hardware).
This allows PCI cards using interrupts to work on hardware for the
first time; this change will also work with QEMU 1.5 or later, where
the equivalent bugs in the modelling of the hardware have been fixed.
Although QEMU will attempt to autodetect whether the kernel is
expecting the long-standing "everything is int 27" mapping or the one
hardware has, for certainty we force it into "definitely behave like
hardware mode"; this will avoid unexpected surprises later if we
implement sparse irqs. This is harmless on hardware.
Thanks to Paul Gortmaker for bisecting the problem and finding an initial
solution, to Russell King for providing the correct interrupt mapping,
and to Guenter Roeck for providing an initial version of this patch
and prodding me into relocating the hardware and retesting everything.
