    This patchset throws out tt mode, which has been non-functional for a while.
    
    This is done in phases, interspersed with code cleanups on the affected files.
    
    The removal is done as follows:
    	remove all code, config options, and files which depend on
    CONFIG_MODE_TT
    	get rid of the CHOOSE_MODE macro, which decided whether to
    call tt-mode or skas-mode code, and replace invocations with their
    skas portions
    	replace all now-trivial procedures with their skas equivalents
    
    There are now a bunch of now-redundant pieces of data structures, including
    mode-specific pieces of the thread structure, pt_regs, and mm_context.  These
    are all replaced with their skas-specific contents.
    
    As part of the ongoing style compliance project, I made a style pass over all
    files that were changed.  There are three such patches, one for each phase,
    covering the files affected by that phase but no later ones.
    
    I noticed that we weren't freeing the LDT state associated with a process when
    it exited, so that's fixed in one of the later patches.
    
    The last patch is a tidying patch which I've had for a while, but which caused
    inexplicable crashes under tt mode.  Since that is no longer a problem, this
    can now go in.
    
    This patch:
    
    Start getting rid of tt mode support.
    
    This patch throws out CONFIG_MODE_TT and all config options, code, and files
    which depend on it.
    
    CONFIG_MODE_SKAS is gone and everything that depends on it is included
    unconditionally.
    
    The few changed lines are in re-written Kconfig help, lines which needed
    something skas-related removed from them, and a few more which weren't
    strictly deletions.
