Blackfin: set ARCH_KMALLOC_MINALIGN

2010-05-22T18:19:13+00:00

Architectures that handle DMA-non-coherent memory need to set
ARCH_KMALLOC_MINALIGN to make sure that kmalloc'ed buffer is DMA-safe:
the buffer doesn't share a cache with the others.

Blackfin: move string functions to normal lib/ assembly

2010-05-22T18:19:09+00:00

Since 'extern inline' doesn't work correctly in the context of the Linux
kernel (too many overriding defines), move the string functions to normal
lib/ assembly files (like the existing mem funcs).  This avoids the forced
inline all over the kernel and allows us to place them constantly in L1.

This also avoids some module failures when gcc inserts calls to string
functions but the kernel build system doesn't fully consult the library
archives.

Blackfin: add support for the DBG (debug output) pseudo insn

2010-05-22T18:19:05+00:00

Another pseudo insn used by Blackfin simulators.  Also factor some now
common register lookup code out of the DBGA handlers.

Blackfin: change the BUG opcode to an unused 16-bit opcode

2010-05-22T18:19:04+00:00

The current BUG opcode includes the bit that flags the insn as a 32bit
opcode, but it wasn't declaring it as 32bits.  So pick an unused 16bit.

Blackfin: add support for the DBGA (debug assert) pseudo insn

2010-05-22T18:18:56+00:00

A few pseudo debug insns exist to make testing of simulators easier.
Since these don't actually exist in the hardware, we have to have the
exception handler take care of emulating these.  This allows sim test
cases to be executed unmodified under Linux and thus simplify debugging
greatly.

Blackfin: SMP: add flush_tlb_kernel_range stub

2010-05-21T13:40:20+00:00

Newer code in mm/page_alloc.c requires this function now in arches.

Blackfin: make hardware trace output a little more useful

2010-05-21T13:40:19+00:00

Decode the vast majority of insns that appear in the trace buffer to get a
better idea of what's going on at a glance.

Blackfin: remove CONFIG_DEBUG_VERBOSE from trace.c

2010-05-21T13:40:18+00:00

Now that the split traps code has moved all the verbose output to the
trace.c file, we can unify all the CONFIG_DEBUG_VERBOSE handling.  This
gets rid of much of the crappy ifdef forest and enables usage of normal
pr_xxx functions so checkpatch stops complaining.

Blackfin: split kernel/traps.c

2010-05-21T13:40:17+00:00

The current kernel/traps.c file has grown a bit unwieldy as more debugging
functionality has been added over time, so split it up into more logical
files.  There should be no functional changes here, just minor whitespace
tweaking.  This should make future extensions easier to manage.
