some architecture updates, driver fixes, the usual...

Please read the detailed changelog for details

Summary of changes from v2.4.27-pre3 to v2.4.27-pre4
============================================

<akepner:sgi.com>:
  o [TG3]: Fix ethtool -S
  o [TG3]: Make sure RX/TX flow control settings actually get set

<felixb:sgi.com>:
  o [XFS] Remove speculative preallocation from linvfs_get_block_core

<fsgqa:sgi.com>:
  o [XFS] Remove the 128K limitation on pagebuf_get_no_daddr() and allow
  the kmem_alloc() to fail. 

<gnb:melbourne.sgi.com>:
  o [TG3]: Count rx_discards in rx_errors
  o [TG3]: Add more ethtool -S stats

<joshk:triplehelix.org>:
  o [SPARC64]: Pull in drivers/i2c/Config.in
  o [SPARC64]: Use $(CC) in check for egcs/gcc3
  o [SPARC64]: Backport some lvalue warning fixes from 2.6.x
  o [SPARC32]: Use $(LD) -V for NEW_GAS check

<jpk:sgi.com>:
  o [XFS] xfs_iomap_write_delay() was doing speculative allocations without
  checking if there were any real blocks already in the speculative
  allocation area. This could result in an allocation that overlaps
  pre-allocated space. This would result in an ASSERT failure in debug
  kernels, or invalid output from xfs_bmap. 
  o [XFS] Add support for allocating additional file space in stripe width
  sized chunks. A new fstab/mount option, "swalloc" has been defined. If
  specified when mounting a striped file system, allocation requests will
  be rounded up to a stripe width if the file size is >= stripe width,
  and the data is being appended to eof. The 'swalloc' option is "off" by
  default. 

<linux-kernel:vortech.net>:
  o [VLAN]: Use KERN_INFO for VLAN_INF

<mhuth:mvista.com>:
  o [IPV6]: Fix sock identity checking bug in tcp_ipv6_check_established

  o cramfs use pagecache
