9ad79b5851 xtensa: drop CONFIG_EMBEDDED_RAMDISK
Remove Kconfig entries, boot subdirectory, dependencies from other
boot-* Makefiles, and sections from ld scripts.

Remove stale redboot code that used to pass initrd addresses in a3 and
a4 to _start.

ee446fd5e6 tokenring: delete all remaining driver support
This represents the mass deletion of the of the tokenring support.

It gets rid of:
  - the net/tr.c which the drivers depended on
  - the drivers/net component
  - the Kbuild infrastructure around it
  - any tokenring related CONFIG_ settings in any defconfigs
  - the tokenring headers in the include/linux dir
  - the firmware associated with the tokenring drivers.
  - any associated token ring documentation.

e335e3eb82 locking/kconfig: Simplify INLINE_SPIN_UNLOCK usage
Get rid of INLINE_SPIN_UNLOCK entirely replacing it with
UNINLINE_SPIN_UNLOCK instead of the reverse meaning.

Whoever wants to change the default spinlock inlining
behavior and uninline the spinlocks for some weird reason,
such as spinlock debugging, paravirt etc. can now all just
select UNINLINE_SPIN_UNLOCK

dcb69290af time: Cleanup old CONFIG_GENERIC_TIME references that snuck in
Awhile back I removed all the CONFIG_GENERIC_TIME referecnes as
the last of the non-GENERIC_TIME arches were converted.

However, due to the functionality being important and around for
awhile, there apparently were some out of tree hardware enablement
patches that used it and have since been merged.

This patch removes the remaining instances of GENERIC_TIME.

6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

173d668138 [PATCH] xtensa: remove extra header files
The Xtensa port contained many header files that were never needed.  This
rather lengthy patch removes all those files.  Unfortunately, there were
many dependencies that needed to be updated, so this patch touches quite a
few source files.
