xtensa: fix linker script transformation for .text.unlikely
Now that binutils generate *.unlikely sections which don't follow
documented (info as) literal section naming rules, section name
transformation script doesn't work well resulting in the following
errors at vmlinux link time:
main.c:(.text.unlikely+0x3): dangerous relocation: l32r: literal
placed after use: .literal.unlikely
Fix section name transformation script by adding specific rule for
.text.unlikely sections.

1) Eric Dumazet discovered and fixed what turned out to be a family of
bugs. These functions were using pskb_may_pull() which might need
to reallocate the linear SKB data buffer, but the callers were not
expecting this possibility. The callers have cached pointers to the
packet header areas, and would need to reload them if we were to
continue using pskb_may_pull().
So they could end up reading garbage.
It's easier to just change these RAW4/RAW6/MIP6 routines to use
skb_header_pointer() instead of pskb_may_pull(), which won't modify
the linear SKB data area.
2) Dave Jone's syscall spammer caught a case where a non-TCP socket can
call down into the TCP keepalive code. The case basically involves
creating a raw socket with sk_protocol == IPPROTO_TCP, then calling
setsockopt(sock_fd, SO_KEEPALIVE, ...)
Fixed by Eric Dumazet.
3) Bluetooth devices do not get configured properly while being powered
on, resulting in always using legacy pairing instead of SSP. Fix
from Andrzej Kaczmarek.
4) Bluetooth cancels delayed work erroneously, put stricter checks in
place. From Andrei Emeltchenko.
5) Fix deadlock between cfg80211_mutex and reg_regdb_search_mutex in
cfg80211, from Luis R. Rodriguez.
6) Fix interrupt double release in iwlwifi, from Emmanuel Grumbach.
7) Missing module license in bcm87xx driver, from Peter Huewe.
8) Team driver can lose port changed events when adding devices to a
team, fix from Jiri Pirko.
9) Fix endless loop when trying ot unregister PPPOE device in zombie
state, from Xiaodong Xu.
10) batman-adv layer needs to set MAC address of software device
earlier, otherwise we call tt_local_add with it uninitialized.
11) Fix handling of KSZ8021 PHYs, it's matched currently by KS8051 but
that doesn't program the device properly. From Marek Vasut.

c/r: prctl: fix build error for no-MMU case
Commit 1ad75b9e1628 ("c/r: prctl: add minimal address test to
PR_SET_MM") added some address checking to prctl_set_mm() used by
checkpoint-restore. This causes a build error for no-MMU systems:
kernel/sys.c: In function 'prctl_set_mm':
kernel/sys.c:1868:34: error: 'mmap_min_addr' undeclared (first use in this function)
The test for mmap_min_addr doesn't make a lot of sense for no-MMU code
as noted in commit 6e1415467614 ("NOMMU: Optimise away the
{dac_,}mmap_min_addr tests").
This patch defines mmap_min_addr as 0UL in the no-MMU case so that the
compiler will optimize away tests for "addr < mmap_min_addr".

lib/flex_proportions.c: fix corruption of denominator in flexible proportions
When racing with CPU hotplug, percpu_counter_sum() can return negative
values for the number of observed events.
This confuses fprop_new_period(), which uses unsigned type and as a
result number of events is set to big *positive* number. From that
moment on, things go pear shaped and can result e.g. in division by
zero as denominator is later truncated to 32-bits.
This bug causes a divide-by-zero oops in bdi_dirty_limit() in Borislav's
3.6.0-rc6 based kernel.
Fix the issue by using a signed type in fprop_new_period(). That makes
us bail out from the function without doing anything (mistakenly)
thinking there are no events to age. That makes aging somewhat
inaccurate but getting accurate data would be rather hard.

"echo" doesn't read from stdin, therefore the checksyscalls script didn't
warn about not implemented system calls anymore since 29dc54c6
("checksyscalls: Use arch/x86/syscalls/syscall_32.tbl as source").
Use "cat" instead of "echo" which handles this correctly.

HID: hid-lg4ff: Set absolute axes parametes on DFP
The lg4ff driver doesn't fill the "input_absinfo" struct so it is left
with default values. Applications with rely on information in this struct
therefore do not work correctly with the wheel.
Other Logitech wheels probably need this fix too, but again I do not have
enough information to write it.

HID: hid-lg4ff: Adjust X axis input value accordingly to selected range.
Range limiting command for the Driving Force Pro wheel is only a FF_SPRING
effect so that the wheel creates resistance when the user tries to turn it past
the limit. It is however possible to overpower the FFB motors quite easily which
leads to the X axis value exceeding the expected limit. This confuses
games which dynamically adjust calibration using the highest/lowest min and max
values reported by the wheel. Joydev device driver also doesn't take in account
any changes in an axis range after the joystick device is created.
This patch recalculates received ABS_X axis value so it is always in
<0; 16383> range where 0 is the left limit and 16383 the right limit.
Logitech driver for Windows does the same thing. As for any concerns about
possible loss of precision, I compared a large set of raw/adjusted values
generated by "mult_frac" to values returned by the Windows driver and I got
a 100% match.
Other Logitech wheels will probably need a similar fix, but I currently lack
the information needed to write one.

Since something will be divided by these variables in
