[PATCH] misc fixes

- Add an explanation for clearing the focus bit on P4 (zwane)

- __d_path kerneldoc fix (John Levon)

- generic-hdlc documentation fix (Krzysztof Halasa <khc@pm.waw.pl>)

- cmdline_read_proc cleanup (Oleg Drokin)

- remove a couple of unused vars from drivers/ide/pci/hpt366.c

- sound/core/sgbuf.c needs mm.h at least on alpha, for mem_map and other
  page stuff.  (Ivan Kokshaysky <ink@jurassic.park.msu.ru>)

- Don't use "u32 long" in cs46xx.c (Kevin Puetz <puetzk@puetzk.org>)

- fs/nfs/nfs4xdr.c warning fix: all the `goto out;' statements are
  commented away, so comment away the label too.

- net/ipv6/af_inet6.c: remove unused var

- drivers/media/video/bttv-cards.c: jiffies are unsigned long

- drivers/media/video/saa7134/saa7134-cards.c: unused var

- Fix Documentation/Changes comment wrt sparc compiler version

- drivers/pnp/quirks.c needs slab.h for kfree().  (Daniele Bellucci
  <bellucda@tiscali.it>)

@@ -83,8 +83,6 @@ almost certainly bugs (mainly, but not exclusively, in the kernel) that
 will need to be fixed in order to use these compilers. In any case, using
 pgcc instead of plain gcc is just asking for trouble.
 
-gcc 2.91.66 (egcs-1.1.2) continues to be supported for SPARC64 requirements.
-
 The Red Hat gcc 2.96 compiler subtree can also be used to build this tree.
 You should ensure you use gcc-2.96-74 or later. gcc-2.96-54 will not build
 the kernel correctly.
