* Significant unification of RAMDISK* config files, making them diffable.deraadt2014-10-101-268/+155
| | | | | | | This makes it easier to remove components not required to do an install, and subsequently add other desireable components ... In snapshots (in various forks) for about a week. Do some upgrades and installs, please.

* boot(9): Reduce annoying style diffsuebayasi2014-07-211-6/+6
| | | | | | | | - 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.

* Tackle the endian.h mess. Make it so that:guenther2014-07-121-3/+5
| | | | | | | | | | | | | | | | | | * 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@
* boot(9): Undo curproc-overriding hacksuebayasi2014-07-111-6/+1
| | | | | | | | | | Some (not all) boot(9) implementations have ancient hacks which overrides if (curproc == NULL). This was probably made in a hope to forcibly proceed various clean-shutdown related code, including VFS shutdown. Let's clarify that clean-shutdown needs process context; it is impossible to cleanly shutdown VFS from within e.g. a panic in SPL_HIGH. OK kettenis@

* CPU_BUSY_CYCLE(): A new MI statement for busy loop power reductionuebayasi2014-07-111-1/+3
| | | | | | | | | | 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@

* boot(9): Remove comments about RB_*, "cold", and savectx()uebayasi2014-07-101-3/+1
| | | | | | | Again remove slightly different comments to reduce diffs. These will be re-added once boot() become MI and its specification is clearly re-defined. OK miod@
* boot(): Remove comments about RB_TIMEBAD to reduce diffsuebayasi2014-07-101-6/+1
| | | | | | | RB_TIMEBAD is documented well enough that the comment is not needed. sparc64 does slightly different and its comment is left with XXX. OK deraadt@ miod@

* bpf code surgery / shuffling / simplification.henning2014-07-091-2/+2
| | | | | | | | | | | | | | | the various bpf_mtap_* are very similiar, they differ in what (and to some extent how) they prepend something, and what copy function they pass to bpf_catchpacket. use an internal _bpf_mtap as "backend" for bpf_mtap and friends. extend bpf_mtap_hdr so that it covers all common cases: if dlen is 0, nothing gets prepended. copy function can be given, if NULL the default bpf_mcopy is used. adjust the existing bpf_mtap_hdr users to pass a NULL ptr for the copy fn. re-implement bpf_mtap_af as simple wrapper for bpf_mtap_hdr. re-implement bpf_mtap_ether using bpf_map_hdr re-implement bpf_mtap_pflog as trivial bpf_mtap_hdr wrapper ok bluhm benno
