c4f895cbe1 [PATCH] splice: cleanup the SPLICE_F_NONBLOCK handling 
- generic_file_splice_read() more readable and correct
- Don't bail on page allocation with NONBLOCK set, just don't allow
  direct blocking on IO (eg lock_page).

9200c0b2a0 [MIPS] Fix Makefile bugs for MIPS32/MIPS64 R1 and R2. 
This fixes kernel builds with gcc 3.2 (not 64-bit, that is looking like
it is beyond recovery) and 3.3.  With these bugs fixed we now also can
get undo 3b4c4996a0c24da9e6f8be764e3950b756b18cc0 and similar bits for
SMTC that were added in 79cc8007b93838a670b164b8a55ab3e735a12a8b.

e4ac58afdf [MIPS] Rewrite all the assembler interrupt handlers to C. 
Saves like 1,600 lines of code, is way easier to debug, compilers
frequently do a better job than the cut and paste type of handlers many
boards had.  And finally having all the stuff done in a single place
also means alot of bug potencial for the MT ASE is gone.

The only surviving handler in assembler is the DECstation one; I hope
Maciej will rewrite it.
