racoon uses a wrong IPsec-SA handle that is for other peer in case it
receives a ISAKMP message for IPsec-SA that has the same message-id as
the message-id that is received before.

racoon uses message-id to find the handle of IPsec-SA.  The message-id
is a unique number for each peer, but different peers may use the same
value.

Different Windows Vista or Windows 7 peers seem to use the same
message-id.  racoon can handle the first Windows's Phase-2, but it
cannot handle the second Windows.  Because racoon misunderstands the
message for the second Windows as the message for the first Windows.

- wait 500ms after sata_reset_interface() before touching SERROR register.
  This is what seems to fix the issue I'm seeming on ESB2 controller.
- The 31s delay didn't cause the probe to fail because of a mismatch

MB_LEN_MAX should moved from MD to MI.

(tnozaki)

avoid mbrtowc/wcrtomb buffer overrun when CPUARCH=hppa and MB_CUR_MAX > 6.
it is not usual case(merely used such mutibyte locale, eg. ja_JP.ISO-2022-JP).

[background]
before merging minoura-xpg4dl branch(2001), we argued and decided to increase
MB_LEN_MAX 1 -> 32 all CPUARCH(*but* we forgot to change it MD to MI).

without knowing that NetBSD/hp700(mergeing -current 2002) incorrectly set
MB_LEN_MAX=6 (maybe this value taken from FreeBSD). but our setlocale(3)
assumes __mb_len_max_runtime as 32, so that mbrtowc/wcrtomb may overrun.

we have to increase hppa's MB_LEN_MAX upto 32, and change it MD to MI
next libc major bump(scheduled next release 6.0).

- add a kmutex_t ci_ctx_lock to struct cpu_info, and initialise it in
  cpu_pmap_init() and replace pmap_ctx_lock usage with this new ci_ctx_lock

- replace smp_dcache_flush_page_all() with smp_dcache_flush_page_cpuset(),
  that flushes only on the set of CPUs not, everyone.  add new
  dcache_flush_page_cpuset() to flush this page from the D$ only
  on the specified set of CPUs.

- add a cpuset to pmap_free_page() and use it when freeing PTE pages
  when a pmap is destroyed

- introduce pmap_free_page_noflush(), and use it when we allocated a
  page for PTEs but didn't use it and don't need to flush it

- don't bother with pmap_lock in pmap_extract(), the only potential
  issue is pseg_get() which is already safe

Put cfdata* in a similar namespace with cfdriver** cfattachinit*.
This was nagging me already yesterday, but I decided to leave it
alone for better compat with old ioconf.c builds.  But as it turns
out, new code depends on newly built ioconf.c with a new config(1)
anyway, so renaming is not an issue (at least not at this stage).

While renaming, namespace cfdriver and cfattach in "ioconf" rather
than "comp", since the former reflects the config(5) keyword.

pckbc.c, vga.c: It doesn't appear to be helpful to compare two
    bus_space_tag_t's in pckbc_is_console() and vga_is_console(), and MI
    code should never do such a thing, so don't do it.

tcic2.c: #if 0 some diagnostic code that compares two bus_space_tag_t's.

ex_softc.ex_bustype is written but never read.  Just get rid of it.

Set/test sc_csr_memmapped instead of comparing bus_space_tag_t's.

(dyoung)

sc_csr_memmapped is true iff the device registers are memory-mapped.
