1a5c5de1b6 [MIPS] IP27: Allow SMP ;-) Another changeset messed up by patch.
When lmo commit 4ef893e0515e8bf336dfbd200884f244869fbb43 was merged to
kernel.org as e73ea273ef patch happily
applied the IP27 segment to IP22.  f63f36c18b11e166d0f362ac04dbcd7e6ea23f9e
did fix the effects partially - and with a wrong log message.  Now fixed
for real (tm).

This reverts commit 31473747bd.

Another amazing example of patch(1) messing up - lmo changeset
66e8560d11d02bcadc261498471831a6375ad046 was merged twice to kernel.org
and ended up doing this rubbish job.

16b7b2ac01 [MIPS] Fixup migration to GENERIC_TIME
Since we already moved to GENERIC_TIME, we should implement alternatives
of old do_gettimeoffset routines to get sub-jiffies resolution from
gettimeofday().  This patch includes:

 * MIPS clocksource support (based on works by Manish Lachwani).
 * remove unused gettimeoffset routines and related codes.
 * remove unised 64bit do_div64_32().
 * simplify mips_hpt_init. (no argument needed, __init tag)
 * simplify c0_hpt_timer_init. (no need to write to c0_count)
 * remove some hpt_init routines.
 * mips_hpt_mask variable to specify bitmask of hpt value.
 * convert jmr3927_do_gettimeoffset to jmr3927_hpt_read.
 * convert ip27_do_gettimeoffset to ip27_hpt_read.
 * convert bcm1480_do_gettimeoffset to bcm1480_hpt_read.
 * simplify sb1250 hpt functions. (no need to subtract and shift)

f8829caee3 [MIPS] Fix aliasing bug in copy_to_user_page / copy_from_user_page
The current implementation uses a sequence of a cacheflush and a copy.
This is racy in case of a multithreaded debuggee and renders GDB
virtually unusable.

Aside this fixes a performance hog rendering access to /proc/cmdline very
slow and resulting in a enough cache stalls for the 34K AP/SP programming
model to make the bare metal code on the non-Linux VPE miss RT deadlines.

The main part of this patch was originally written by Ralf Baechle;
Atushi Nemoto did the the debugging.
