The uevent callback doesn't protect its access to
last_request, which now causes a warning since
the conversion to get_last_request(). Fix this by
allowing to use RCU protection for last_request.

Correct operation for register writes is to perform a busy-wait
after writing the register. Currently the busy wait it performed
before, meaning subsequent register writes to bitfields may occur
before the previous field has been updated.
Also, all registers are defined as 32-bit read/write. Change
pwm_busy_wait() to use readl rather than readb.
Improve readability of code with defines for registers and bitfields.

People are back from the holiday breaks, and it shows. Here are a bunch of
fixes for a number of platforms:
- A couple of small fixes for Nomadik
- A larger set of changes for kirkwood/mvebu
- uart driver selection, dt clocks, gpio-poweroff fixups,
a few __init annotation fixes and some error handling improvement
in their xor dma driver.
- i.MX had a couple of minor fixes (and a critical one for flexcan2
clock setup)
- MXS has a small board fix and a framebuffer bugfix
- A set of fixes for Samsung Exynos, fixing default bootargs and some
Exynos5440 clock issues
- A set of OMAP changes including PM fixes and a few sparse warning
fixups
All in all a bit more positive code delta than we'd ideally want to see
here, mostly from the OMAP PM changes, but nothing overly crazy.

We have skb_mac_header_was_set() helper to tell if mac_header
was set on a skb. We would like the same for transport_header.
__netif_receive_skb() doesn't reset the transport header if already
set by GRO layer.
Note that network stacks usually reset the transport header anyway,
after pulling the network header, so this change only allows
a followup patch to have more precise qdisc pkt_len computation

Paul Gortmaker says:
====================
I'd like to propose that we get rid of these old 8390 EISA drivers.
Of the five deleted here, I wrote four -- and while that doesn't give
me any authority for deletion above anyone else, it does at least
allow me to comment on the absolute absence of anyone reaching
out to the driver author for assistance in the last dozen years.
Eventually we'll probably get rid of EISA bus support, since in
x86, the hardware is close to 20 years old and already too resource
constrained to be useful today. However there might still be
a few DEC Alpha enthusiasts with old EISA machines kept alive,
and so I expect we'll have to wait a bit longer to get unanimous
agreement to proceed with the full EISA removal (although I'd
love to be proven wrong on that).
Most of the DEC Alpha machines shipped in a PCI configuration, and
even the few that were EISA had DEC tulip based ethernet and no
reason to be needing the inferior 8390 technology. So the interest
here for any possible DEC enthusiasts with EISA boxes about these
old 8390 drivers should be nil.
These really were rare cards -- in fact the smc-ultra32 is the only
one that I'd ever seen in person. Even back in the mid 90's when
the drivers were written, I would guess that the user base was less
than 10 people across all of them.
The following patch was created with --irreversible-delete for
ease of review (it skips showing the content of files that are
deleted); however the complete patch can be pulled as per below.
