Pull Documentation updates from Jonathan Corbet:
"It's been a relatively busy cycle for docs:
- A fair pile of RST conversions, many from Mauro. These create more
than the usual number of simple but annoying merge conflicts with
other trees, unfortunately. He has a lot more of these waiting on
the wings that, I think, will go to you directly later on.
- A new document on how to use merges and rebases in kernel repos,
and one on Spectre vulnerabilities.
- Various improvements to the build system, including automatic
markup of function() references because some people, for reasons I
will never understand, were of the opinion that
:c:func:``function()`` is unattractive and not fun to type.
- We now recommend using sphinx 1.7, but still support back to 1.4.
- Lots of smaller improvements, warning fixes, typo fixes, etc"

Convert the pcmcia docs to ReST format. Most of the changes here
are trivial.
The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

This function was created as a deprecated fallback case back in 2010 by
commit eb14120f743d ("pcmcia: re-work pcmcia_request_irq()") for legacy
cases.
Actual in-kernel users haven't been around for a long while. The last
in-kernel user was apparently removed four years ago by commit
5f5316fcd08e ("am2150: Update nmclan_cs.c to use update PCMCIA API").
Just remove it entirely.

Dave Hinds pointed out to me that 37979e1546a7 will break b43 and
ray_cs, as IOCARD is not -- as the name would suggest -- only needed
for cards using IO ports. Instead, as it re-deines several pins, it
is also required for using interrupts.

When CONF_AUTO_SET_IO or CONF_AUTO_SET_IOMEM are set, the corresponding
fields in struct pcmcia_device *p_dev->resource[0,1,2] are set
accordinly. Drivers wishing to override certain settings may do so in
the callback function, but they no longer need to parse the CIS entries
stored in cistpl_cftable_entry_t themselves.

pcmcia_enable_device() now replaces pcmcia_request_configuration().
Instead of config_req_t, all necessary flags are either passed as
a parameter to pcmcia_enable_device(), or (in rare circumstances)
set in struct pcmcia_device -> flags.
With the last remaining user of include/pcmcia/cs.h gone, remove

Clean up the alloc_io_space() function by moving most of it to
the actual resource_ops. This allows for a bit less re-directions.
Future cleanups will follow, and will make up for the code
duplication currently present between rsrc_iodyn and rsrc_nonstatic
(which are hardly ever built at the same time anyway, therefore no
increase in built size).

Instead of the old pcmcia_request_irq() interface, drivers may now
choose between:
- calling request_irq/free_irq directly. Use the IRQ from *p_dev->irq.
- use pcmcia_request_irq(p_dev, handler_t); the PCMCIA core will
clean up automatically on calls to pcmcia_disable_device() or
device ejection.
- drivers still not capable of IRQF_SHARED (or not telling us so) may
use the deprecated pcmcia_request_exclusive_irq() for the time
being; they might receive a shared IRQ nonetheless.

Signed-off-by: Dominik Brodowski <[email protected]>

As a replacement to pcmcia_get_{first,next}_tuple() and
pcmcia_get_tuple_data(), three new -- and easier to use --
functions are added:
- pcmcia_get_tuple() to get the very first CIS entry of one
type.
- pcmcia_loop_tuple() to loop over all CIS entries of one type.
- pcmcia_get_mac_from_cis() to read out the hardware MAC address
from CISTPL_FUNCE.
Only a handful of drivers need these functions anyway, as most
CIS access is already handled by pcmcia_loop_config(), which
now shares the same backed (pccard_loop_tuple()) with
pcmcia_loop_tuple().
A pcmcia_get_mac_from_cis() bug noted by Komuro
<[email protected]> has been fixed in this revision.
