Make spinlocks etc use subsections of their parent sections instead of
an ELF section of their own - needed for newer binutils when the parent
sector is removed. 

Newer Athlons have means of checking if they are SMP capable or not.
This code adds checks that printk a warning on systems not intended
for SMP, and set the taint flag that modutils is already aware of.
The taint code is also improved to use defines instead of magic numbers.

swap_info_struct became pretty much superfluous.  As we are minimizing
kdev_t usage anyway, I took the opportunity to remove swap_device
member, and replace the remaining usages with SWP_BLOCKDEV bit flag.

Adding SWP_BLOCKDEV in turn motivated a small cleanup of the
SWP_xxx bit flags and their usage.

Patch has been in light testing for a couple weeks, and
has been glanced at by Al.  "looks sane"

* Initialize interface carrier state in speedo_open.
* Update previous netif_carrier_{on,off} change to use
  linux/mii.h constants.

on all RX interrupts.  Prior to this fix, RX FIFO overrun and RX
buffer overrun interrupts did not trigger an RX poll; now they do.

via netif_carrier_{on,off}.  Some placeholders to do this were
already in the code, making this an even easier and more obvious patch.

Also, decrease time until next link beat check, if link beat
is not present.  (previously the code would wait 60 seconds until
next check, regardless of current link state)

* Add support for Conexant tulip clones.
* Do not store eeprom data on stack (128 or 512 bytes), it's a
large object, and also, we already have a copy in kmalloc'd RAM.

s/PORT_/PCNET32_PORT_/ for local constants, to avoid conflicting
with linux/ethtool.h.

"some" systems with "some" cables see a large amount of errors,
due to a hardware bug.  This bug is (apparently) not probe-able;
however it only appears on rare reference boards and the like,
so we simply add a config option and default the option to OFF.

Further detail:
When CONFIG_NATSEMI_CABLE_MAGIC option is enabled, PMDCSR_VAL
register value becomes 0x1898, a value provided by a NatSemi
app note.  This enables a workaround for a hardware bug
which is (apparently) not probe-able.  Luckily the hardware bug
is (apparently) not common either, so we default to disabling
this workaround.

the size of the Tx data buffer list without cause.
Spotted by Dave Jones.

nfsd_read() slightly cleaned up.

initialize proc_inode properly for /proc/self/

logics in nfsd_lookup() cleaned up (see above, only more so ;-/)

new helper - exp_get_by_name(client, vfsmount, dentry).  Used
in places where we travers mountpoint.

logics in exp_get() cleaned up (it's kernel, not IOCCC, damnit...)

exp_child() and exp_parent() take super_block instead of kdev_t.

exp_find() is gone (never used).

unused arguments (and dead code) removed from exp_rootfh().

Get rid of NFSCTL_GETFH.

    - fix the replacement mistake of xxx_thread_flag
    - fix the miss test of PT_PTRACED flag

OGAWA Hirofumi <hirofumi@mail.parknet.co.jp>

The first fix changes get_wchan() and the second one fixed what DaveM noticed.

Fixe another typo in the recent llseek cleanups.  Typo was spotted by
Miloslav Trmac ...  hopefully the last.

Switch over ext3, ufs, reiserfs, msdos, vfat, isofs, qnx4, hpfs, efs,
udf, romfs, bfs, affs, hfs, adfs, cramfs, ntfs, jffs, jffs2 and freevxfs
to new ->get_sb(). 

Kill ->read_super() that is thus no longer used.

syscall latency improvement

 * There's now an asm/thread_info.h header file with the basic structure
   def and asm offsets in it.

 * There's now a linux/thread_info.h header file which includes the asm
   version and wraps some bitops calls to make convenience functions for
   accessing the low-level flags. 

 * The task_struct has had some fields removed (and some flags), and has
   acquired a pointer to the thread_info struct.

 * task_struct's are now allocated on slabs in kernel/fork.c, whereas
   thread_info structs are allocated at the bottom of the stack pages.

 * Some more convenience functions are provided at the end of linux/sched.h to
   access flags in other tasks (these are here because they need to access the
   task_struct).
