ecd972e9cb include the sparc loadfile_machdep.h as-is; we can blow this header away 
completely later.

51a53de0d5 Preparation for the future introduction of multibyte locale. 
- MB_LEN_MAX is increased to 32.
 - To ensure binary compatibility for old executables
   under multibyte locale, versioned setlocale is added.
 - __mb_len_cur definision is added in setlocale.c
   and enable it in stdlib.h .
   It is also important for multibyte locale stuffs,
   but I just forgot.

3143adecfb Tell gcc that stores clobber "memory". Probably makes no difference since 
they should not be used to access normal memory anyway.

e5cd515b89 Upgrate interrupt handling: 
1) use interrupt vectors for specific zs chips rather than polling
	   all of them.

	2) use softintr_schedule() and schedule it for a particular device
	   rather than poll all devices.

406e0f779f Add a `device class' interrupt level argument (from machine/intr.h) 
to bus_interrupt_establish().

It's currently only used in sparc64/dev/psycho.c to assign a CPU interrupt
level to devices in PCI slots.

d738f90fd7 raise MSIZE from 128 to 256. 
- for sizeof(void *) == 8 arch, this is mandatory.  MHLEN is too small
  already (less than 80) and there are chances for unwanted packet loss due
  to m_pullup restriction.
- for other cases, the change should avoid allocating clusters in most cases
  (even when you have IPv4 IPsec tunnel, or IPv6 with moderate amount of
  extension header)

portmasters: if your arch chokes with the change (high memory usage or
whatever), please backout the change for your arch.

889c658b5b Change the kernel mmap interface so that the offset to map is an 
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes.  Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".

Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.

85cab8fe27 More VM cleanup: 
Move the cpu_info structure above the interrupt stack so it won't
	get corrupted if the stack overflows.

	Flush the D$ before and after all MMU bypass accesses since the
	D$ latches all of those.
