to continue registering it from platform code. In fact, if we continue

Pull Sparc updates from David S. Miller:

 1) Remove the idiotic situation wherein Leon was a special case in all
    of the TLB/cache handling code.

    The worst side effect of this bogosity is that you couldn't build a
    kernel with Leon support enabled (to get better build coverage), and
    test boot it on a non-LEON cpu.

    Leon is, in all core respects, programatically identical to the
    32-bit SRMMU.  Except that they put the TLB registers in a different
    alternate address space location.

    Through code patching (for fast paths) and run time checks, this
    issue is now a thing of the past.

    From Sam Ravnborg.

 2) There was a mis-merge of arch/sparc/Kconfig for one of the
    clockevents changes that went in, causing 32-bit sparc to start
    failing to build.

    I merged in your tree to get those clockevents changes (and added a
    note to the merge commit) then added Stephen Rothwell's fix for the
    merge error.

 3) Software quad floating point emulation was not working properly on
    more recent Niagara chips, because the way the situation is reported
    by the cpu has changed.

    Nobody noticed because gcc emits calls to software emulation
    routines in glibc.
