de71467ca7 make bus_dmamem_alloc always allocate a new map like we are suppose to.. 
This was found when I tried to run the usb code on my arm board...

19015c15ed fix arm wrt to busdma... 
also wrap the two macros that have bare if's w/ do {} while(0) so that
my epe driver doesn't get a warning about braces around confused else...

5974e5c71c Refactor the bus_dma header files so that the interface is described in 
sys/bus_dma.h instead of being copied in every single arch.  This slightly
reorders a flag that was specific to AXP and thus changes the ABI there.
The interface still relies on bus_space definitions found in <machine/bus.h>
so it cannot be included on its own yet, but that will be fixed at a later
date.  Add an MD <machine/bus_dma.h> for ever arch for consistency and to
allow for future MD augmentation of the API.  sparc64 makes heavy use of
this right now due to its different bus_dma implemenation.

5d18cf7825 Use __func__ in the KTR_BUSDMA traces. This avoids copy and paste 
errors like in the bus_dmamap_load_mbuf_sg() case where we were wrongly
displaying the function name as bus_dmamap_load_mbuf.

7a7e7cf91e Use [ldr|str]t instead of [ldr|str] when accessing ARM_TP_ADDRESS. 2005-03-06 21:12:03 +00:00
Olivier Houchard
da53588551 Make sure ARM_TP_ADDRESS is accessible right now by calling pmap_fault_fixup, 
as we can't rely on a trap happening, as it is done normally.
While I'm there, uncomment the call to cpu_dcache_wbinv_range() in
pmap_kenter_internal, as we don't call cpu_dcache_wbinv_all() there anymore.

2ba823e954 Unlike NetBSD's bcopy(), our bcopy allows the two strings to overlap, even in 
kernel. So bring in the userland version, instead of just calling memcpy.

a5f50ef9e4 netchild's mega-patch to isolate compiler dependencies into a central 
place.

This moves the dependency on GCC's and other compiler's features into
the central sys/cdefs.h file, while the individual source files can
then refer to #ifdef __COMPILER_FEATURE_FOO where they by now used to
refer to #if __GNUC__ > 3.1415 && __BARC__ <= 42.

By now, GCC and ICC (the Intel compiler) have been actively tested on
IA32 platforms by netchild.  Extension to other compilers is supposed
to be possible, of course.

f4c01f1508 Instead of using sysarch() to store-retrieve the tp, add a magic address, 
ARM_TP_ADDRESS, where the tp will be stored. On CPUs that support it, a cache
line will be allocated and locked for this address, so that it will never go
to RAM. On CPUs that does not, a page is allocated for it (it will be a bit
slower, and is wrong for SMP, but should be fine for UP).
The tp is still stored in the mdthread struct, and at each context switch,
ARM_TP_ADDRESS gets updated.
