In case if epoll_ctl is called with operation EPOLL_CTL_DEL then
@epds.events variable allocated on stack may contain random bits which
we test then for EPOLLEXCLUSIVE.  Since currently the test look like

	if (epds.events & EPOLLEXCLUSIVE) {
		if (op == EPOLL_CTL_MOD)
			goto error_tgt_fput;
		if (op == EPOLL_CTL_ADD && (is_file_epoll(tf.file) ||
				(epds.events & ~EPOLLEXCLUSIVE_OK_BITS)))
			goto error_tgt_fput;
	}

Nothing serious will happen even if epds.events has this bit set, still
better to be on safe side and make sure that we're to test this bit at
all.

Currently all the p_paddr of PT_LOAD headers are assigned to 0, which is
not true and could be misleading, since 0 is a valid physical address.

User space tools like makedumpfile needs to know physical address for
PT_LOAD segments of direct mapped regions.  Therefore this patch updates
paddr for such regions.  It also sets an invalid paddr (-1) for other
regions, so that user space tool can know whether a physical address
provided in PT_LOAD is correct or not.

I do not know why it was 0, which is a valid physical address.  But
certainly, it might break some user space tools, and those need to be
fixed.  For example, see following code from kexec-tools

kexec/kexec-elf.c:build_mem_phdrs()

                    if ((phdr->p_paddr + phdr->p_memsz) < phdr->p_paddr) {
                            /* The memory address wraps */
                            if (probe_debug) {
                                    fprintf(stderr, "ELF address wrap around\n");
                            }
                            return -1;
                    }

We do not need to perform above check for an invalid physical address.

I think, kexec-tools and makedumpfile will need fixup.  I already have
those fixup which will be sent upstream once this patch makes through.
Pro with this approach is that, it will help to calculate variable like
page_offset, phys_base from PT_LOAD even when they are randomized and
therefore will reduce many variable and version specific values in user
space tools.

Having an ASLR offset information can help to translate an identity
mapped virtual address to a physical address.  But that would be an
additional field in PT_LOAD header structure and an arch dependent
value.

Moreover, sending a valid physical address like 0 does not seem right.
So, IMHO it is better to fix that and send valid physical address when
available (identity mapped).

GUI environments seem to be becoming more agressive at scanning
filesystems, to the point where autofs cannot expire mounts at all.

This is one key reason the update of the autofs dentry info last_used
field is done in the expire system when the dentry is seen to be in use.

But somewhere along the way instances of the update has crept back into
the autofs path walk functions which, with the more aggressive file
access patterns, is preventing expiration.

Changing the update in the path walk functions allows autofs to at least
make progress in spite of frequent immediate re-mounts from file
accesses.

Often all is needed is these small helpers, instead of compiler.h or a
full kprobes.h.  This is important for asm helpers, in fact even some
asm/kprobes.h make use of these helpers...  instead just keep a generic
asm file with helpers useful for asm code with the least amount of
clutter as possible.

Likewise we need now to also address what to do about this file for both
when architectures have CONFIG_HAVE_KPROBES, and when they do not.  Then
for when architectures have CONFIG_HAVE_KPROBES but have disabled
CONFIG_KPROBES.

Right now most asm/kprobes.h do not have guards against CONFIG_KPROBES,
this means most architecture code cannot include asm/kprobes.h safely.
Correct this and add guards for architectures missing them.
Additionally provide architectures that not have kprobes support with
the default asm-generic solution.  This lets us force asm/kprobes.h on
the header include/linux/kprobes.h always, but most importantly we can
now safely include just asm/kprobes.h on architecture code without
bringing the full kitchen sink of header files.

Two architectures already provided a guard against CONFIG_KPROBES on its
kprobes.h: sh, arch.  The rest of the architectures needed gaurds added.
We avoid including any not-needed headers on asm/kprobes.h unless
kprobes have been enabled.

In a subsequent atomic change we can try now to remove compiler.h from
include/linux/kprobes.h.

During this sweep I've also identified a few architectures defining a
common macro needed for both kprobes and ftrace, that of the definition
of the breakput instruction up.  Some refer to this as
BREAKPOINT_INSTRUCTION.  This must be kept outside of the #ifdef
CONFIG_KPROBES guard.

Change the zpool/compressor param callback function to release the
zswap_pools_lock spinlock before calling param_set_charp, since that
function may sleep when it calls kmalloc with GFP_KERNEL.

While this problem has existed for a while, I wasn't able to trigger it
using a tight loop changing either/both the zpool and compressor params; I
think it's very unlikely to be an issue on the stable kernels, especially
since most zswap users will change the compressor and/or zpool from sysfs
only one time each boot - or zero times, if they add the params to the
kernel boot.

  RDMA stack to use the core DMA mapping code.

  This resulted in a nice set of cleanups, but touched the entire tree

Linux 4.10

The Kconfig currently controlling compilation of this code is:

drivers/platform/x86/Kconfig:config INTEL_TURBO_MAX_3
drivers/platform/x86/Kconfig:   bool "Intel Turbo Boost Max Technology 3.0 enumeration driver"

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.

We do uncover some implicit includes during build coverage that
were hidden behind the module.h which pulls in a lot of dependants.
