kprobes test cases need to have a stack that is aligned to an 8-byte
boundary because they call other functions (and the ARM ABI mandates
that alignment) and because test cases include 64-bit accesses to the
stack. Unfortunately, GCC doesn't ensure this alignment for inline
assembler and for the code in question seems to always misalign it by
pushing just the LR register onto the stack. We therefore need to
explicitly perform stack alignment at the start of each test case.
Without this fix, some test cases will generate alignment faults on
systems where alignment is enforced. Even if the kernel is configured to
handle these faults in software, triggering them is ugly. It also
exposes limitations in the fault handling code which doesn't cope with
writes to the stack. E.g. when handling this instruction
strd r6, [sp, #-64]!
the fault handling code will write to a stack location below the SP
value at the point the fault occurred, which coincides with where the
exception handler has pushed the saved register context. This results in
corruption of those registers.

This is arm port of commit 737480a0d525 ("kprobes/x86:
Fix the return address of multiple kretprobes").
Fix the return address of subsequent kretprobes when multiple
kretprobes are set on the same function.
For example:
# cd /sys/kernel/debug/tracing
# echo "r:event1 sys_symlink" > kprobe_events
# echo "r:event2 sys_symlink" >> kprobe_events
# echo 1 > events/kprobes/enable
# ln -s /tmp/foo /tmp/bar
(without this patch)
# cat trace | grep -v ^#
ln-82 [000] dn.2 68.446525: event1: (kretprobe_trampoline+0x0/0x18 <- SyS_symlink)
ln-82 [000] dn.2 68.447831: event2: (ret_fast_syscall+0x0/0x1c <- SyS_symlink)
(with this patch)
# cat trace | grep -v ^#
ln-81 [000] dn.1 39.463469: event1: (ret_fast_syscall+0x0/0x1c <- SyS_symlink)

Kprobes/arm skips single-stepping (moreover handling the event)
if the conditional instruction must not be executed. This
also apply the rule when we hit the recursing kprobe, so
that kprobe does not count nmissed up in that case.

This is arm port of commit 6a5022a56ac3 ("kprobes/x86: Allow to
handle reentered kprobe on single-stepping")
Since the FIQ handlers can interrupt in the single stepping
(or preparing the single stepping, do_debug etc.), we should
consider a kprobe is hit in the NMI handler. Even in that
case, the kprobe is allowed to be reentered as same as the
kprobes hit in kprobe handlers
(KPROBE_HIT_ACTIVE or KPROBE_HIT_SSDONE).
The real issue will happen when a kprobe hit while another
reentered kprobe is processing (KPROBE_REENTER), because
we already consumed a saved-area for the previous kprobe.

Greg upon trying to boot no-MMU Kernel on ARM926EJ reported boot
failure. He root caused it to ID_PFR1 access introduced by the
commit mentioned in the fixes tag below.
All CP15 processors need not have processor feature registers, only
for architectures defined by CPUID scheme would have it. Hence check
for it before accessing processor feature register, ID_PFR1.

dma_get_sgtable() tries to create a scatterlist table containing valid
struct page pointers for the coherent memory allocation passed in to it.
However, memory can be declared via dma_declare_coherent_memory(), or
via other reservation schemes which means that coherent memory is not
guaranteed to be backed by struct pages. In such cases, the resulting
scatterlist table contains pointers to invalid pages, which causes
kernel oops later.
This patch adds detection of such memory, and refuses to create a
scatterlist table for such memory.

KVM/ARM Fixes for v4.11-rc6
Fixes include:
- Fix a problem with GICv3 userspace save/restore
- Clarify GICv2 userspace save/restore ABI
- Be more careful in clearing GIC LRs
- Add missing synchronization primitive to our MMU handling code

We currently have some code to clear the list registers on GICv3, but we
never call this code, because the caller got nuked when removing the old
vgic. We also used to have a similar GICv2 part, but that got lost in
the process too.
Let's reintroduce the logic for GICv2 and call the logic when we
initialize the use of hypervisors on the CPU, for example when first
loading KVM or when exiting a low power state.

In kvm_free_stage2_pgd() we don't hold the kvm->mmu_lock while calling
unmap_stage2_range() on the entire memory range for the guest. This could
cause problems with other callers (e.g, munmap on a memslot) trying to
unmap a range. And since we have to unmap the entire Guest memory range
holding a spinlock, make sure we yield the lock if necessary, after we
unmap each PUD range.

ASoC: Fixes for v4.11
A relatively large pile of fixes for mainline, the first since the merge
window. The biggest block of changes here by volume is the sun8i-codec
set, the driver was newly added in the merge window but it was realized
that renaming some of the user visible controls was required so these
are being pushed for v4.11 to avoid the original code appearing in a
release. Otherwise it's all fairly standard bugfix stuff.

driver so the audio-routing in the device tree must be renamed too.

The libgpio code pre-sets the GPIO values for the gpio-reset in the
device tree. This results in the device being reset during bringup.
To prevent this pre-setting, use the "open-source" flag in the device

On some DDR controllers, compatible with the sama5d3 one,
the sequence to enter/exit/re-enter the self-refresh mode adds
more constrains than what is currently written in the at91_idle
driver. An actual access to the DDR chip is needed between exit
and re-enter of this mode which is somehow difficult to implement.
This sequence can completely hang the SoC. It is particularly
experienced on parts which embed a L2 cache if the code run
between IDLE calls fits in it...
Moreover, as the intention is to enter and exit pretty rapidly
from IDLE, the power-down mode is a good candidate.
So now we use power-down instead of self-refresh. As we can
simplify the code for sama5d3 compatible DDR controllers,
we instantiate a new sama5d3_ddr_standby() function.

This reverts commit cab43282682e ("ARM: at91/dt: sama5d2: Use new
compatible for ohci node")
It depends from commit 7150bc9b4d43 ("usb: ohci-at91: Forcibly suspend
ports while USB suspend") which was reverted and implemented
differently. With the new implementation, the compatible string must
remain the same.
The compatible string introduced by this commit has been used in the
default SAMA5D2 dtsi starting from Linux 4.8. As it has never been
working correctly in an official release, removing it should not be
breaking the stability rules.

The bl_en_pin GPIO pinmux is configured as "gpio_in", which makes it
conflicts with the real GPIO usage (out), and makes the backlight not
usable.
Drop the GPIO pinmux for it, thus this GPIO can be correctly used.

The CPU port of the BCM53125 is configured with RGMII (no delays) but
this should actually be RGMII with transmit delay (rgmii-txid) because
STMMAC takes care of inserting the transmitter delay. This fixes
occasional packet loss encountered.

The Mali clock rate was improperly assumed to be 408MHz, while it was
really 384Mhz, 408MHz being the "extreme" frequency, and definitely not
stable.
Switch for the stable, correct frequency for the GPU.

After issuing a 'reboot' command the imx6sx-udoo-neo board does not
reboot as expected and it just hangs instead.
In mainline kernel only LDO enabled mode is supported. Do not provide
arm-supply/soc-supply nodes in the device tree, so that the board operates
in LDO enabled mode and can then successfully reboot via watchdog.

of_find_node_by_name() drops the reference to the passed device node.
The commit referenced above exposes this problem.
To fix the problem, use of_get_child_by_name() instead of
of_find_node_by_name(); of_get_child_by_name() does not drop
the reference count of passed device nodes. While semantically
different, we only look for immediate children of the passed
device node, so of_get_child_by_name() is a more appropriate
function to use anyway.
Release the reference to the device node obtained with
of_get_child_by_name() after it is no longer needed to avoid
another device node leak.
While at it, clean up the code and change the return type of
omap3xxx_hwmod_is_hs_ip_block_usable() to bool to match its use
and the return type of of_device_is_available().

Commit d9d9cec02835 ("ARM: OMAP2+: Remove legacy data from hwmod for
omap3") dropped platform data that should no longer be used as we're
booting with device tree. It turns out that smartreflex is still
using platform data and produces the following errors during probe:
smartreflex smartreflex.0: invalid resource
smartreflex smartreflex.0: omap_sr_probe: ioremap fail
smartreflex: probe of smartreflex.0 failed with error -22
smartreflex smartreflex.1: invalid resource
smartreflex smartreflex.1: omap_sr_probe: ioremap fail
smartreflex: probe of smartreflex.1 failed with error -22
Let's fix the regression by adding back the smartreflex hwmod data.
The long term is to update the smartreflex driver to use device tree
based probing.

This pull request contains Broadcom ARM-based SoC Device Tree fixes for 4.11,
please pull the following:
- Jon fixes the UART output on the Broadcom bcm953012k reference board by
using the proper clock reference instead of hard-coding the baud rate
- Jon also fixes the memory map on the bcm953012k reference board by using
the appropriate physical RAM start address
- Jon finally fixes the interrupt type for the Cortex A9 global and local
timers found in the BCM5301X SoC (Norsthar).

Memory starts at 0x80000000, not 0. 0 "works" due to mirrior of the

Pull KVM fixes from Radim Krčmář:
"ARM updates from Marc Zyngier:
- vgic updates:
- Honour disabling the ITS
- Don't deadlock when deactivating own interrupts via MMIO
- Correctly expose the lact of IRQ/FIQ bypass on GICv3
- I/O virtualization:
- Make KVM_CAP_NR_MEMSLOTS big enough for large guests with many
PCIe devices
- General bug fixes:
- Gracefully handle exception generated with syndroms that the host
doesn't understand
- Properly invalidate TLBs on VHE systems
x86:
- improvements in emulation of VMCLEAR, VMX MSR bitmaps, and VCPU
reset

arm/arm64 architecture doesnt use private memslots, hence removing
KVM_PRIVATE_MEM_SLOTS macro definition.
