e951f85b1a Allow VM_NFREELIST in uao_set_pgfl, meaning any freelist is OK. 2014-05-25 18:55:11 +00:00

c20b71f6fe Add uao_set_pgfl to limit a uvm_aobj's pages to a specified freelist. 
Brought up on tech-kern:

1b07394016 Don't leak memory on failure in uvm_pglistalloc_contig. 
Free pages like uvm_pglistalloc_simple does.

Discovered by code inspection.

1627c0ae4a Allow this to handle H/W tlbs. Some ARM allow for a cheap way to flush all 
entries using an ASID from the TLB.  Add support for taking advantage of it.
Most ARMs don't have an easy way to find out what's in the TLB so make
record_asids can just say all ASIDs are in use.  Fix some off by 1 errors.

a68f9396b6 Change (mostly mechanically) every cdevsw/bdevsw I can find to use 
designated initializers.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.

1a23213bde Use UVMHIST_INITIALIZER (KERNHIST_INITIALIZER) to statically initialize 
maphist.  This allows maphist to used very very early in boot well before
uvm has been initialized.

the sysctl link sets are processed, and remove redundancy.

XXX: Ports that provide their own VM_DEFAULT_ADDRESS() need to provide the
two new flavors, otherwise they get the default ones now.

ff2955473b Re-instate the zero length sections in elf core dumps (they probably help 
describe the process memory layout).
Fudge the a.out core code to not dump the entire contents.
I'm not sue that anything can read a.out core files - more progress might
  be made on such dumps by converting the a.out file to elf!

825d1920ba There is no need for uvm_coredump_walkmap() to explicity pass the proc_t 
pointer to the calller's function.
If the code needs the process its address can be placed in the caller's
  cookie.

7a743f3de6 Minor changes to the process coredump code. 
- Add some extra comments.
- Add some XXX comments because the process state might not be stable,
- Add uvm_coredump_count_segs() to simplify the calling code.
- uvm code now only returns non-empty sections/segments.
- Put the 'iocookie' into the 'cookie' block passed to uvm_coredump_walkmap()
  instead of passing it through as an additional parameter.
amd64 can still generate core dumps that gdb can read.

be74e0a9c9 Change the type of the 'cookie' that holds the state of the core dump file 
from 'void *' to the actual type 'struct coredump_iostate *'.
In most of the code the contents of the structure are still unknown.
This just stops the wrong type of pointer being passed to the 'void *'
parameter.
I hope I've found everything, amd64 GENERIC and i386 GENERIC & ALL compile.

d31af930cb Allow MD code to add aditional checks for mmap(..., MAP_FIXED) address 
ranges. This can be used, for example, to avoid not implemented VA-holes,
but we probably need to check in a few more places.
