Add code to recognize SPARC-Sonoma cpu correctly and update cpu hardware
caps and cpu distribution map. SPARC-Sonoma is based upon SPARC-M7 core
along with additional PCI functions added on and is reported by firmware
as "SPARC-SN".

The function pcibios_add_device() added by commit d0c31e020057
("sparc/PCI: Fix for panic while enabling SR-IOV") initializes
the dev_archdata by doing a memcpy from the PF. This has the
problem that it erroneously copies the OF device without
explicitly refcounting it.
As David Miller pointed out: "Generally speaking we don't
really support hot-plug for OF probed devices, but if we did
all of the device tree pointers have to be refcounted properly."
To fix this error, and also avoid code duplication, this patch
creates a new helper function, pci_init_dev_archdata(), that
initializes the fields in dev_archdata, and can be invoked
by callers after they have taken the needed refcounts

When using the Virtualisation Host Extensions, EL1 is not used in
the host and requires no separate configuration.
In addition, with VHE enabled, non-hyp-specific EL2 configuration
that does not need to be done early will be done anyway in
__cpu_setup via the _EL1 system register aliases. In particular,
the layout and definition of CPTR_EL2 are changed by enabling VHE
so that they resemble CPACR_EL1, so existing code to initialise
CPTR_EL2 becomes architecturally wrong in this case.
This patch simply skips the affected initialisation code in the
non-VHE case.

There is a race with multi-threaded applications between context switch and
pagetable upgrade. In switch_mm() a new user_asce is built from mm->pgd and
mm->context.asce_bits, w/o holding any locks. A concurrent mmap with a
pagetable upgrade on another thread in crst_table_upgrade() could already
have set new asce_bits, but not yet the new mm->pgd. This would result in a
corrupt user_asce in switch_mm(), and eventually in a kernel panic from a
translation exception.
Fix this by storing the complete asce instead of just the asce_bits, which
can then be read atomically from switch_mm(), so that it either sees the
old value or the new value, but no mixture. Both cases are OK. Having the
old value would result in a page fault on access to the higher level memory,
but the fault handler would see the new mm->pgd, if it was a valid access
after the mmap on the other thread has completed. So as worst-case scenario
we would have a page fault loop for the racing thread until the next time
slice.
Also remove dead code and simplify the upgrade/downgrade path, there are no
upgrades from 2 levels, and only downgrades from 3 levels for compat tasks.
There are also no concurrent upgrades, because the mmap_sem is held with
down_write() in do_mmap, so the flush and table checks during upgrade can
be removed.

After a failure during registration of the dma_table (because of the
function being in error state) we free its memory but don't reset the
associated pointer to zero.
When we then receive a notification from firmware (about the function
being in error state) we'll try to walk and free the dma_table again.
Fix this by resetting the dma_table pointer. In addition to that make
sure that we free the iommu_bitmap when appropriate.

On all shmobile ARM SoCs, loop-based delays may complete early, which
can be after only 1/3 (Cortex A9) or 1/2 (Cortex A7 or A15) of the
minimum required time.
This is caused by calculating preset_lpj based on incorrect assumptions
about the number of clock cycles per loop:
- All of Cortex A7, A9, and A15 run __loop_delay() at 1 loop per
CPU clock cycle,
- As of commit 11d4bb1bd067f9d0 ("ARM: 7907/1: lib: delay-loop: Add
align directive to fix BogoMIPS calculation"), Cortex A8 runs
__loop_delay() at 1 loop per 2 instead of 3 CPU clock cycles.
On SoCs with Cortex A7 and/or A15 CPU cores, this went unnoticed, as
delays use the ARM arch timer if available. R-Car Gen2 doesn't work if
the arch timer is disabled. However, APE6 can be used without the arch
timer.

In head.S, the str_l macro, which takes a source register, a symbol name
and a temp register, is used to store a status value to the variable
__early_cpu_boot_status. Subsequently, the value of the temp register is
reused to invalidate any cachelines covering this variable.
However, since str_l resolves to
adrp \tmp, \sym
str \src, [\tmp, :lo12:\sym]
the temp register never actually holds the address of the variable but
only of the 4 KB window that covers it, and reusing it leads to the
wrong cacheline being invalidated. So instead, take the address
explicitly before doing the store, and reuse that value to perform
the cache invalidation.

We need to update the user TM feature bits (PPC_FEATURE2_HTM and
PPC_FEATURE2_HTM) to mirror what we do with the kernel TM feature
bit.
At the moment, if firmware reports TM is not available we turn off
the kernel TM feature bit but leave the userspace ones on. Userspace
thinks it can execute TM instructions and it dies trying.
This (together with a QEMU patch) fixes PR KVM, which doesn't currently
support TM.

The REAL_LE feature entry in the ibm_pa_feature struct is missing an MMU
feature value, meaning all the remaining elements initialise the wrong
values.
This means instead of checking for byte 5, bit 0, we check for byte 0,
bit 0, and then we incorrectly set the CPU feature bit as well as MMU
feature bit 1 and CPU user feature bits 0 and 2 (5).
Checking byte 0 bit 0 (IBM numbering), means we're looking at the
"Memory Management Unit (MMU)" feature - ie. does the CPU have an MMU.
In practice that bit is set on all platforms which have the property.
This means we set CPU_FTR_REAL_LE always. In practice that seems not to
matter because all the modern cpus which have this property also
implement REAL_LE, and we've never needed to disable it.
We're also incorrectly setting MMU feature bit 1, which is:
#define MMU_FTR_TYPE_8xx 0x00000002
Luckily the only place that looks for MMU_FTR_TYPE_8xx is in Book3E
code, which can't run on the same cpus as scan_features(). So this also
doesn't matter in practice.
Finally in the CPU user feature mask, we're setting bits 0 and 2. Bit 2
is not currently used, and bit 0 is:
#define PPC_FEATURE_PPC_LE 0x00000001
Which says the CPU supports the old style "PPC Little Endian" mode.
Again this should be harmless in practice as no 64-bit CPUs implement
that mode.
Fix the code by adding the missing initialisation of the MMU feature.
Also add a comment marking CPU user feature bit 2 (0x4) as reserved. It
would be unsafe to start using it as old kernels incorrectly set it.

Make sure that s390 appears to be a big endian machine by defining
this config option.
Without this s390 appears to be little endian as seen by e.g. the
recordmount script: "perl ./scripts/recordmcount.pl "s390" "little"
"64""
This has no practical impact within the script since the endian
variable is only evaluated for mips. However there are already a
couple of common code places which evaluate this config option. None
of them is relevant for s390 currently though.
To avoid any issues in the future (and fix the recordmcount oddity)
add the new config option.

arch_spin_lock_wait_flags() checks if a spinlock is not held before
trying a compare and swap instruction. If the lock is unlocked it
tries the compare and swap instruction, however if a different cpu
grabbed the lock in the meantime the instruction will fail as
expected.
Subsequently the arch_spin_lock_wait_flags() incorrectly tries to
figure out if the cpu that holds the lock is running. However it is
using the wrong cpu number for this (-1) and then will also yield the
current cpu to the wrong cpu.
Fix this by adding a missing continue statement.

Depending on timing during the resume path from off mode on 36xx, we may
see external aborts. These seem to be caused by the following:
- OMAP3 Advisory 1.62 "MPU Cannot Exit from Standby" says we need to
disable intc autoidle before WFI
- DM3730 Advisory 1.106 "MPU Leaves MSTANDBY State Before IDLEREQ of
Interrupt Controller is Released" says we need to wait before
accessing intc
omap3_intc_resume_idle restores the intc autoidle for all resume paths,
however in the resume path from off mode only it is also being restored
by omap_intc_restore_context before this call to omap3_intc_resume_idle
happens. The second restore of the intc autoidle in this path is what
appears to be causing the external abort so for the off mode resume path
let's rely on omap_intc_restore_context to restore intc autoidle, and
for all other paths let omap3_intc_resume_idle handle it as it is now.

When we loop over all queued machine check error records to pass them
to the registered notifiers we use llist_for_each_entry(). But the loop
calls gen_pool_free() for the entry in the body of the loop - and then
the iterator looks at node->next after the free.
Use llist_for_each_entry_safe() instead.

With commit 7b91369b4655 ("mmc: sdhci: Set DMA mask when adding host")
DMA access got disabled for device drivers with zero DMA mask property.
sdhci-esdhc-imx got blocked from DMA access by this. Hence: initialize
the DMA mask to enable access again.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
Fixes for omaps against v4.6-rc1. Mostly minor fixes for the newer
SoCs with few board fixes and a fix for a long time hwmod bug:
- Fix cpsw_emac0 link type for baltos-ir5221
- Fix interrupt type for TWD
- Fix edma memcpy channel allocation for am43x
- Fix am43x-epos sycntimer32k by using the correct assigned clock
- Fix interconnect barrier for dra7
- Fix a long time hwmod bug for updating sysconfig register properly
- Fix flakey booting on dm814x where USB reset needs a delay
And there is one minor change that is not strictly a fix, but is
good to have for proper hardware detection:
- Detect dra7 silicon revision 2.0 properly

My intention was to ioremap a 4-byte register. Coincidentally enough,
sizeof(SZ_4) equals to SZ_4, but this code is weird anyway.

The ColdFire architecture specific gpio support code registers a sysfs
bus device named "gpio". This clashes with the new generic API device
added in commit 3c702e99 ("gpio: add a userspace chardev ABI for GPIOs").
The old ColdFire sysfs gpio device was never used for anything specific,
and no links or other nodes were created under it. The new API sysfs gpio
device has all the same default sysfs links (device, drivers, etc) and
they are properly populated.
Remove the old ColdFire sysfs gpio registration.
