The C operator <= defines a perfectly fine total ordering on the set of
values representable in a long.  However, unlike its namesake in the
integers, it is not translation invariant, meaning that we do not have
"b <= c" iff "a+b <= a+c" for all a,b,c.

This means that it is always wrong to try to boil down the relationship
between two longs to a question about the sign of their difference,
because the resulting relation [a LEQ b iff a-b <= 0] is neither
anti-symmetric or transitive.  The former is due to -LONG_MIN==LONG_MIN
(take any two a,b with a-b = LONG_MIN; then a LEQ b and b LEQ a, but a !=
b).  The latter can either be seen observing that x LEQ x+1 for all x,
implying x LEQ x+1 LEQ x+2 ...  LEQ x-1 LEQ x; or more directly with the
simple example a=LONG_MIN, b=0, c=1, for which a-b < 0, b-c < 0, but a-c >
0.

Note that it makes absolutely no difference that a transmogrying bijection
has been applied before the comparison is done.  In fact, had the
obfuscation not been done, one could probably not observe the bug
(assuming all values being compared always lie in one half of the address
space, the mathematical value of a-b is always representable in a long).
As it stands, one can easily obtain three file descriptors exhibiting the
non-transitivity of kcmp().

Side note 1: I can't see that ensuring the MSB of the multiplier is
set serves any purpose other than obfuscating the obfuscating code.

This patch avoids fuse hangs on sh4 by flushing the cache on
get_user_pages_fast().  This is not necessary a good thing to do, but
get_user_pages() does this, so get_user_pages_fast() should too.

Please note the patch for mips arch that addresses the similar problem:
  https://kernel.googlesource.com/pub/scm/linux/kernel/git/ralf/linux/+/linux-3.4.50%5E!/#F0

They basically simply disable get_user_pages_fast() at all, using a

explicit cache flushes.

When calling epoll_ctl with operation EPOLL_CTL_DEL, structure epds is
not initialized but ep_take_care_of_epollwakeup reads its event field.
When this unintialized field has EPOLLWAKEUP bit set, a capability check
is done for CAP_BLOCK_SUSPEND in ep_take_care_of_epollwakeup.  This
produces unexpected messages in the audit log, such as (on a system
running SELinux):

We shouldn't set text_len in the code path that detects printk recursion
because text_len corresponds to the length of the string inside textbuf.
A few lines down from the line

    text_len = strlen(recursion_msg);

is the line

    text_len += vscnprintf(text + text_len, ...);

So if printk detects recursion, it sets text_len to 29 (the length of
recursion_msg) and logs an error.  Then the message supplied by the
caller of printk is stored inside textbuf but offset by 29 bytes.  This
means that the output of the recursive call to printk will contain 29
bytes of garbage in front of it.

This defect is caused by commit 458df9fd ("printk: remove separate
printk_sched buffers and use printk buf instead") which turned the line

    text_len = vscnprintf(text, ...);

into

    text_len += vscnprintf(text + text_len, ...);

To fix this, this patch avoids setting text_len when logging the printk
recursion error.  This patch also marks unlikely() the branch leading up
to this code.

ForcePads are found on HP EliteBook 1040 laptops. They lack any kind of
physical buttons, instead they generate primary button click when user
presses somewhat hard on the surface of the touchpad. Unfortunately they
also report primary button click whenever there are 2 or more contacts
on the pad, messing up all multi-finger gestures (2-finger scrolling,
multi-finger tapping, etc). To cope with this behavior we introduce a
delay (currently 50 msecs) in reporting primary press in case more
contacts appear.

This reverts commit 232de514 ("ACPI / battery: fix wrong value of
capacity_now reported when fully charged")

There is nothing wrong or unexpected about 'capacity_now' increasing above
the last 'full_charge_capacity' value. Different charging cycles will cause
'full_charge_capacity' to vary, both up and down.  Good battery firmwares
will update 'full_charge_capacity' when the current charging cycle is
complete, increasing it if necessary. It might even go above
'design_capacity' on a fresh and healthy battery.

Capping 'capacity_now' to 'full_charge_capacity' is plain wrong, and
printing a warning if this doesn't happen to match the 'design_capacity'
is both annoying and terribly wrong.

This results in bogus warnings on perfectly working systems/firmwares:

 [Firmware Bug]: battery: reported current charge level (39800) is higher than reported maximum charge level (39800).

and wrong values being reported for 'capacity_now' and
'full_charge_capacity' after the warning has been triggered.

Capping 'capacity_now' to 'full_charge_capacity' is plain wrong. If this

protection against being applied to working firmwares.

Good battery firmwares will allow 'capacity_now' to increase above
'full_charge_capacity', and will update the latter when the battery
is fully charged.  By capping 'capacity_now' we lose accurate capacity
reporting until charging is complete whenever 'full_charge_capacity'
needs to be increased.

also depends on the modules number in Makefile. The related information
in "scripts/Makefile.lib" line 94:

  # $(modname_flags) #defines KBUILD_MODNAME as the name of the module it will
  # end up in (or would, if it gets compiled in)
  # Note: Files that end up in two or more modules are compiled without the
  #       KBUILD_MODNAME definition. The reason is that any made-up name would
  #       differ in different configs.

For this case, 'radio-si470x-i2c.o' and 'radio-si470x-common.o' are in
one line, so cause compiling issue. And 'uaccess.h' is a common shared
header (not specially for drivers), so use pr_devel() instead of is OK.

"entry.h" needs 'asmlinkage', and "asm/linkage.h" does not provide it.
So need include "linux/linkage.h" to use generic one instead of.

CONFIG_FHANDLE is a requirement for systemd and with the increasing
uptake of systemd within distros it makes sense for 64 bit defconfigs
to include it.
