ide-cs.c is the only PCMCIA device driver making use of CONFIG_PCMCIA_DEBUG,
so convert it to use the dynamic debug infrastructure.

Also, remove all usages of the CS_CHECK macro and replace them with proper
Linux style calling and return value checking. The extra error reporting may
be dropped, as the PCMCIA core already complains about any (non-driver-author)
errors.

Use the generic "dynamic debug" infrastructure instead of
CONIG_PCMCIA_DEBUG in the PCMCIA core (pcmcia.ko and pcmcia_core.ko). To
enable debugging, enable CONFIG_DYNAMIC_DEBUG, mount debugfs and

$ echo -n 'module pcmcia_core +p' > /sys/kernel/debug/dynamic_debug/control

for the complete module "pcmcia_core", for example. For more detailled
instructions, please see Documentation/dynamic-debug-howto.txt

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
<komurojun-mbn@nifty.com> has been fixed in this revision.

Use pcmcia_loop_config() in a few drivers missed during the first
round. On fmvj18x_cs.c it -- strangely -- only requries us to set
conf.ConfigIndex, which is done by the core, so include an empty
loop function which returns 0 unconditionally.

A few PCMCIA network drivers can make use of values provided by the pcmcia
core, instead of tedious, independent CIS parsing.

xirc32ps_cs.c: manf_id

hostap_cs.c: multifunction count

b43/pcmcia.c: ConfigBase address and "Present"

smc91c92_cs.c:  By default, mhz_setup() can use VERS_1 as it is stored
in struct pcmcia_device. Only some cards require workarounds, such as
reading out VERS_1 twice.

As the PCMCIA core already determines the multifunction count, the
ConfigBase address and the Present value, we can use them directly
instead of parsing the CIS again. By making use of pcmcia_loop_config(),
we can further remove the remaining call to pcmcia_get_first_tuple()
and friends.

pccard_read_tuple(), which is only used by the PCMCIA core, should
handle TUPLE_RETURN_COMMON more sensibly: If a specific function (which
may be 0) is requested, set tuple.Attributes = 0 as was done in all
PCMCIA drivers. If, however, BIND_FN_ALL is requested, return the
"common" tuple. As to the callers of pccard_read_tuple():

- All calls to pcmcia_validate_cis() had set the "function" parameter to
  BIND_FN_ALL. Therefore, remove the "function" parameter and make the
  parameter to pccard_read_tuple explicit.

- Calls to CISTPL_VERS_1 and CISTPL_MANFID now set BIND_FN_ALL. This was
  already the case for calls to CISTPL_LONGLINK_MFC.

  x86, perf_event: Rename 'performance counter interrupt'

The destination keyring specified to request_key() and co. is made available to
the process that instantiates the key (the slave process started by
/sbin/request-key typically).  This is passed in the request_key_auth struct as
the dest_keyring member.

keyctl_instantiate_key and keyctl_negate_key() call get_instantiation_keyring()
to get the keyring to attach the newly constructed key to at the end of
instantiation.  This may be given a specific keyring into which a link will be
made later, or it may be asked to find the keyring passed to request_key().  In
the former case, it returns a keyring with the refcount incremented by
lookup_user_key(); in the latter case, it returns the keyring from the
request_key_auth struct - and does _not_ increment the refcount.

The latter case will eventually result in an oops when the keyring prematurely
runs out of references and gets destroyed.  The effect may take some time to
show up as the key is destroyed lazily.

To fix this, the keyring returned by get_instantiation_keyring() must always
have its refcount incremented, no matter where it comes from.

This can be tested by setting /etc/request-key.conf to:

#OP	TYPE	DESCRIPTION	CALLOUT INFO	PROGRAM ARG1 ARG2 ARG3 ...
#======	=======	===============	===============	===============================
create  *	test:*		*		|/bin/false %u %g %d %{user:_display}
negate	*	*		*		/bin/keyctl negate %k 10 @u

and then doing:

	keyctl add user _display aaaaaaaa @u
        while keyctl request2 user test:x test:x @u &&
        keyctl list @u;
        do
                keyctl request2 user test:x test:x @u;
                sleep 31;
                keyctl list @u;
        done

which will oops eventually.  Changing the negate line to have @u rather than
%S at the end is important as that forces the latter case by passing a special
keyring ID rather than an actual keyring ID.
