2014-07-21boot(9): Reduce annoying style diffsMasao Uebayashi
- Always use either: ((x & RB_XXX) != 0) or ((x & RB_XXX) == 0) in boolean context (mostly if (x), or x ? y : z) - prom_halt() in alpha is confirmed to take int as boolean Converted by coccinelle. No functional change intended.

2014-07-12reboot(9), panic(9): Call panic(9) for unrecoverable MD H/W errors (NMIs)Masao Uebayashi
Some architectures have ability to detect hardware sanity and notify system (NMI, firmware callback, etc.). Handle these hardware severe errors, same as software errors, with panic(9). According to miod@, SGI IP27 NMI is triggered by pushing some "hidden" button, which "usual" users/admins don't know. Pushing such a button is "RB_USERREQ" (human-triggered) in that the button is pushed by a human, but not "RB_USERREQ" in that no user intervention in system (== no command input) is done. miod@ agreed that changing these from RB_USERREQ to !RB_USERREQ (== panic(9)) is not a big problem.

2014-07-12reboot(9): Shutdown system by signaling init(8) from kernel where appropriateMasao Uebayashi
Some ports watch temperature in MD and try to shutdown system, when overheated, by calling directly (re)boot(9). Change this to signal init(8) from kernel, as acpi(4) and acpitz(4) do, which has been more tested. This also helps to clarify design that ``clean shutdown must be always started by init(8)''. Note that SIGUSR2 causes init(8) to call reboot(2) with RB_POWERDOWN, as acpi(4) etc. already does. It is reasonable, pointed out by kettenis@, considering system is overheated and immediate reboot may be dangerous. OK deraadt@ miod@

2014-07-12Tackle the endian.h mess. Make it so that:Philip Guenther
* you can #include <sys/endian.h> instead of <machine/endian.h>, and ditto <endian.h> (fixes code that pulls in <sys/endian.h> first) * those will always export the symbols that POSIX specified for <endian.h>, including the new {be,le}{16,32,64}toh() set. c.f. http://austingroupbugs.net/view.php?id=162 if __BSD_VISIBLE then you also get the symbols that our <machine/endian.h> currently exports (ntohs, NTOHS, dlg's bemtoh*, etc) * when doing POSIX compiles (not __BSD_VISIBLE), then <netinet/in.h> and <arpa/inet.h> will *stop* exporting the extra symbols like BYTE_ORDER and betoh* ok deraadt@
2014-07-12boot(9), reboot(9): Migrate MD callers of boot(9) to reboot(9)Masao Uebayashi
I have found that some ports call boot(9) from machine-dependent code to reboot system. These should be changed to either: - Sending signal to init(8) to trigger it to shutdown system cleanly, like acpi(4) does, in cases where found problems don't prevent system from working immediately, or - Just doing panic(9) if the situation is severely broken. For now, just rewrite boot() to reboot(). Actual fixes follow. Discussed with & OK from kettenis@
2014-07-11"It's not the years, honey; it's the mileage."Ted Unangst
bluetooth support doesn't work and isn't going anywhere. the current design is a dead end, and should not be the basis for any future support. general consensus says to whack it so as to not mislead the unwary.
2014-07-11CPU_BUSY_CYCLE(): A new MI statement for busy loop power reductionMasao Uebayashi
The new CPU_BUSY_CYCLE() may be put in a busy loop body so that CPU can reduce power consumption, as Linux's cpu_relax() and FreeBSD's cpu_spinwait(). To start minimally, use PAUSE on i386/amd64 and empty on others. The name is chosen following the existing cpu_idle_*() functions. Naming and API may be polished later. OK kettenis@

2014-07-10boot(9): Remove comments about RB_*, "cold", and savectx()Masao Uebayashi

with softraid(4) disks. softraid(4) is the last real consumer of the doshutdownhooks(9) API and it is not trivial to convert its hook to a DVACT_POWERDOWN handler since the latter does not allow to sleep.
