- Avoid false sharing.
- Make the turnstile hash function more suitable.
- Increase turnstile hash table size.
- Make amends by having only one set of system wide sleep queue hash locks.

autounmountd(8) uses doubles to handle mount time durations. However,
it must convert to integer types, time_t in particular, to do anything
meaningful. Additionally, even though it's a floating-point value in
seconds, the sub-seconds component is never used, so it's unnecessary.
Switching type to time_t fixes an assertion on powerpc64, which checks
that a sleep value that's not -1.0 is greater than 0. On powerpc64, it
happens that the value of -1.0 gets loaded as a float (perhaps a bug in
gcc), but gets compared to a double. This compares as false, so follows
through the 'sleep != -1.0' path, and fails the assert. Since the
sub-second component isn't used in the double, just drop it and deal
with whole-integer seconds.

* XXX Hack alert. GCC 8.3 mis-compiles this function and calls
* strncmp() with the wrong second pointer, as seen in PR#54703.
*
* Until the real cause is located, work around it by using -O1
* for this function.
this hack is restricted to i386.
and remove all #ifdef COREDUMP conditional compilation. Now, the
coredump module is completely separated from the emulation modules, and
they can all be independently loaded and unloaded.
Welcome to 9.99.18 !
- Zero-clear regs64 so that random values are not written into the
preserved registers.
- Cast 32-bit registers (int) to u_int, in order to avoid undesired
sign extension when filled into 64-bit registers (long).

neither auto nor 1000baseT. Use correct index for mii_media_table[].
History: mii_anar() is first added in OpenBSD and ported to NetBSD. On NetBSD,
only atphy(4) use this function. mii_physubr.c rev. 1.75 changed mii_anar()
for simplify. It changed the argument from the ifmedia word to ifm_data used
in our MII API, but the caller have not been changed. And then, PR kern/50206
was reported and the caller was modified by me to prevent panic but it was not
correct fix.
between action and name. Use this table as the example for populating by npfctl.
Drop the int-block table, it's quite cumbersome to have a firewall which
needs the internal network lists added if reboot. Use the localnet variable to
indicated which network we should pass in traffic from instead.
It's required for hardware full reset and it't not requred on soft reset.
When ihphy.c was added in 9 years ago, some workaround code were not in
if_wm.c yet and the initialization code was not good.
Therefore, we must use __attribute__((__aligned__(4))) for them.
netbsd32_{,u}int64 are provided for this purpose. However, we
cannot use it in <compat/sys/siginfo.h> due to circular dependency
b/w <machine/netbsd32_machdep.h>.
In order to distangle it, we choose here to have a duplicate type,
netbsd32_siginfo_uint64, in <compat/sys/siginfo.h>. The equivalence
with netbsd32_uint64 is asserted in <compat/netbsd32/netbsd32.h>.
Now, gdb for i386 works again on amd64 kernel.
Based on patch provided by kamil. Thanks!
