* Move the common bits of syscall invocation and return handling intoguenther2012-08-071-45/+11
| | | | | | | | | | an MI file, <sys/syscall_mi.h>, correcting inconsistencies and the handling when copyin() of arguments fails. Tested on i386, amd64, sparc64, and alpha (thanks naddy@) Any issues with other platforms will be fixed in tree. header name from millert@; ok miod@

| | | | | | | | | MI float.h which pulls in and defines the values that are needed from there, and repair sys/limits.h so that it defines the values it needs as well (depending on POSIX version, XPG version, etc). guenther has a more exact selection of that coming for limits.h. this also fixes a few mistakes for the vax. reviewed by kettenis and guenther.

* Introduce pci_probe_device_hook(pci_chipset_tag_t, struct pci_attach_args *).miod2011-10-101-1/+2
| | | | | | | | | | | | | | | | | | This mandatory function will get invoked in pci_probe_device(), and allows a pci host driver to alter the pci_attach_args passed to a device when attaching. This function will also, if returning non-zero, cause the device to be skipped completely during all the phases of the PCI device discovery (i.e. ressource enumeration, ressource assignment, and actual attachment). This particular feature is experimental and might be reverted in the future (or the scope narrowed to device attachment only). A dummy #define pci_probe_device_hook() 0 is added to all platforms except sgi, where real functions (currently only returning 0) are added; real meat will be added shortly. Discussed at s2k11, no objection from the usual suspects.

* None of the mainbus child devices care about getting a bus_space_tag_t frommiod2011-09-226-992/+22
| | | | | | | | | its parent, because they know better; so don't bother providing one, which allows more unused code to go to the Attic. While there, redo the config machinery for mainbus child devices, to bring it to our current standards. This also allows them to be disabled in UKC, should there be a need for this in the future.

| | | | | | | | | | | | | | | | keep: - remove bootconfig parameter passing feature (unused). - unifdef __PROG32 and remove all remains of arm26 code. - remove ARMFPE support (unused). - remove support for ARM2, ARM2AS, ARM3, ARM6, ARM7, ARM7TDMI and StrongARM processor families, and the related silicon bug workarounds (especially the SA-110 STM^ bug). - remove cpu_functions no longer necessary after previous removals. - remove ARM32_DISABLE_ALIGNMENT_FAULTS option (unused). - make FIQ support conditional on option FIQ (unused, but may be eventually). Discussed with drahn@ and jasper@ long ago, I was sitting on this commit for no good reason.

| | | | | | | | | | via readdoslabel(), tweak writedisklabel() to write disklabels at the same place readdoslabel() reads them from. Irregardless of the physical disk sector size. As is done in i386/amd64 already. No change in behaviour for the 'normal' 512-byte sector case. ok deraadt@

| | | | | | | | | | | | | | | i386. Stop abusing it on other archs for controling a shutdown by pressing the soft power button: * Add a MI sysctl hw.allowpowerdown; if set to 1 (the default) it allows a power button shutdown. * Make acpi(4)/acpibtn(4) honor hw.allowpowerdown. * Switch the various power button intercepts on landisk, sgi, sparc64 and zaurus over to hw.allowpowerdown. * Garbage collect the machdep.kbdreset sysctl on all archs other than amd64 and i386. ok miod@
