the kernel is missing the newline at the end of the file, the string
doesn't get closed properly, resulting in a message from the compiler
about a missing #endif. It's somewhat misleading, so config will now
point it out and compensate for the missing newline.
Addresses PR kern/21920: including kernel config fails in some cases.
still possible for multiple threads to write into the same space, but
they shouldn't be able to corrupt the write pointer in the process.
Also, check for pointer-lapping a bit more carefully in the wrap
vs. non-wrap case.
Use swapctl() for all swap operations.
Remove md_upgrade_mbrtype() from arc and hpcmips ports.
(I haven't finalised what I'm doing about type 165 partitions, but the
existing code is borked.)
enabled on amd64). Add a dmat64 field to various PCI attach structures,
and pass it down where needed. Implement a simple new function called
pci_dma64_available(pa) to test if 64bit DMA addresses may be used.
This returns 1 iff _PCI_HAVE_DMA64 is defined in <machine/pci_machdep.h>,
and there is more than 4G of memory.
causes makefs(8) failure on big endian machines. Pointed out by tsubai.
XXX The real problem is that some sources include {.CURDIR}/ffs/ffs_extern.h

with a more generic "devmap" structure that can also handle mappings
made with large and small pages. Add new pmap routines to enter these
mappings during bootstrap (and "remember" the devmap), and routines to
look up the static mappings once the kernel is running.
use malloc/free for array of pointers to vm_page.
otherwise, use on-stack array as used to.
this change fixes assertion failure when nfsd gets a big read request
that isn't aligned with filesystem block.

manner as the ifaddr hash table. By doing this, the mkludge code can go
away. At the same time, keep track of what pcbs are using what ifaddr and
when an address is deleted from an interface, notify/abort all sockets
that have that address as a source. Switch IGMP and multicasts to use pools
for allocation. Fix a number of potential problems in the igmp code where
allocation failures could cause a trap/panic.
