14 of our 17 architectures define sys_pause exactly the same
way.  The other three don't define it at all.  I assume glibc
translates pause() into sigsuspend() or something.

In favour of those now in kernel.h..

Three arch-determining symbols in drivers/mtd/maps/Config.in are wrong.
They have apparently been generated using the sensible pattern "CONFIG_FOO"
for an architecture "foo"; unfortunately the architectures are not sensible.

  CONFIG_SPARC should be CONFIG_SPARC32
  CONFIG_I386 should be CONFIG_X86
  CONFIG_SH should be CONFIG_SUPERH

Removed a spurious menu definition which was both a duplicate and
had no matching "endmenu".

Removed an "endmenu" for which there was no opening "mainmenu_option".

The config language is *not* shell.  The construct "[ foo ] || [ bar ]"
is legal in shell but not in the config language, where we should use
the equivalent "[ foo -o bar ]"

The format for the "choice" statement is:

  choice 'prompt' "{sub-prompt sub-symbol}*" default-value

and the following is *not* legal config language (note the
positioning of the closing double quote):

  choice 'prompt' "{sub-prompt sub-symbol}* default-value"

It only happens to work because of a combination of accidental
side effects of the current parsers:

  *   unpaired sub-words inside the 2nd word are silently ignored
  *   the missing last word is silently treated as if empty

Two symbols used in drivers/net/wan/Config.in are misspelled.

CONFIG_PPP_MULTLINK should be CONFIG_PPP_MULTILINK
CONFIG_PPP_SYNCTTY should be CONFIG_PPP_SYNC_TTY
