Add new functions that free unused swap slots in batches without
the need to reacquire swap info lock. This improves scalability

The patch is to improve the scalability of the swap out/in via using
fine grained locks for the swap cache. In current kernel, one address
space will be used for each swap device. And in the common
configuration, the number of the swap device is very small (one is
typical).
We can avoid needlessly allocating page for swap slots that
are not used by anyone. No pages have to be read in for
these slots.

In the 4.9 kernel, virtually-mapped stacks will be supported and enabled by
default on x86_64. This has been exposing a number of problems in which
on-stack buffers are being passed into the crypto API, which to support crypto
accelerators operates on 'struct page' rather than on virtual memory.

In preparation for defining KERNEL_START on ARM, rename KERNEL_START to
PART_KERNEL_START, and to be consistent, do this for all
partition-related constants.

In preparation for adding CONFIG_DEBUG_VIRTUAL support, define a set of
common constants: KERNEL_START and KERNEL_END which abstract
CONFIG_XIP_KERNEL vs. !CONFIG_XIP_KERNEL. Update the code where
relevant.

This patch series builds on top of Laura's [PATCHv5 00/10] CONFIG_DEBUG_VIRTUAL
for arm64 to add support for CONFIG_DEBUG_VIRTUAL for ARM.
This was tested on a Brahma B15 platform (ARMv7 + HIGHMEM + LPAE).
Note that the treewide changes would involve a huge CC list, which
is why it has been purpo
All low-level PM/SMP code using virt_to_phys() should actually use
__pa_symbol() against kernel symbols. Update code where relevant to move
away from virt_to_phys().

x86 has an option: CONFIG_DEBUG_VIRTUAL to do additional checks on
virt_to_phys calls. The goal is to catch users who are calling
virt_to_phys on non-linear addresses immediately. This includes caller
using __virt_to_phys() on image addresses instead of __pa_symbol(). This
is a generally useful deb

This discussion was for stalls specifically, rather than for routine
scans of the bitmasks.
But it does look to save some code, so

I just got the ack on the DT bindings for VEC, so I'd like to get it
pulled if we can. If it's too late for 4.10, I'm fine waiting.
Adding VEC support should have a low chance of regressions because it
doesn't get a mode configured by default. This is due to it reporting
unknown connector state
If CONFIG_DEBUG_TEST_DRIVER_REMOVE option is enabled a number of false
positives are reported for ATA controller drivers, because ATA port
probes are done asynchronously, and the same problem may also touch
other asynchronously probed drivers.
To reduce the rate of false reports on boot call async

When trying to configure crashkernel greater than about 800 MB, the
kernel fails to allocate memory on x86 and x86_64. This is due to an
undocumented limit that the crashkernel and other low memory items must
be allocated below 896 MB unless the ",high" option is given. This
updates the documentati
Hi Mathias,
ehci_irq(), ohci_irq(), fotg210_irq(), and oxu210_hcd_irq() contain code
equivalent to this:
status = ehci_readl(...);
if (status == ~(u32) 0) {
...
usb_hc_died(hcd);
...
return IRQ_HANDLED;
}
xhci_irq() has a similar check, but does not call usb_hc_died():

Some versions of ARM GCC compiler such as Android toolchain throws in a
'-fpic' flag by default. This causes the gcc-goto check script to fail
although some config would have '-fno-pic' flag in the KBUILD_CFLAGS.
This patch passes the KBUILD_CFLAGS to the check script so that the
script does not r
