b832a7e505 Create new wrapper function: bus_delayed_attach_children()
Delay the attachment of children, when requested, until after interrutps are
running. This is often needed to allow children to run transactions on i2c or
spi busses. It's a common enough idiom that it will be useful to have its own
wrapper.

4b7ec27007 - There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
  (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
  since r52045) but even recently added device drivers do this unnecessarily.

bb6bb7fe1b - Change ichsmb(4) to follow the format of all the other smbus controllers
for slave addressing by using left-adjusted slave addresses (i.e.
  xxxxxxx0b).
- Require the low bit of the slave address to always be zero in smb(4) to
  help catch broken applications.
- Adjust some code in the IPMI driver to not convert the slave address for
  SSIF to a right-adjusted address.  I (or possibly ambrisko@) added this in
  the past to (unknowingly) work around the bug in ichsmb(4).

85064e683c Various updates to most of the smbus(4) drivers:
- Use printf() and device_printf() instead of log() in ichsmb(4).
- Create the mutex sooner during ichsmb(4) attach.
- Attach the interrupt handler later during ichsmb(4) attach to avoid
  races.
- Don't try to set PCIM_CMD_PORTEN in ichsmb(4) attach as the PCI bus
  driver does this already.
- Add locking to alpm(4), amdpm(4), amdsmb(4), intsmb(4), nfsmb(4), and
  viapm(4).
- Axe ALPM_SMBIO_BASE_ADDR, it's not really safe to write arbitrary values
  into BARs, and the PCI bus layer will allocate resources now if needed.
- Merge intpm(4) and intsmb(4) into just intsmb(4).  Previously, intpm(4)
  attached to the PCI device and created an intsmb(4) child.  Now,
  intsmb(4) just attaches to PCI directly.
- Change several intsmb functions to take a softc instead of a device_t
  to make things simpler.

7048a99c30 Minor overhaul of SMBus support:
- Change smbus_callback() to pass a void * rather than caddr_t.
- Change smbus_bread() to pass a pointer to the count and have it be an
  in/out parameter.  The input is the size of the buffer (same as before),
  but on return it will contain the actual amount of data read back from
  the bus.  Note that this value may be larger than the input value.  It
  is up to the caller to treat this as an error if desired.
- Change the SMB_BREAD ioctl to write out the updated struct smbcmd which
  will contain the actual number of bytes read in the 'count' field.  To
  preserve the previous ABI, the old ioctl value is mapped to SMB_OLD_BREAD
  which doesn't copy the updated smbcmd back out to userland.  I doubt anyone
  actually used the old BREAD anyway as it was rediculous to do a bulk-read
  but not tell the using program how much data was actually read.
- Make the smbus driver and devclass public in the smbus module and
  push all the DRIVER_MODULE()'s for attaching the smbus driver to
  various foosmb drivers out into the foosmb modules.  This makes all
  the foosmb logic centralized and allows new foosmb modules to be
  self-contained w/o having to hack smbus.c everytime a new smbus driver
  is added.
- Add a new SMB_EINVAL error bit and use it in place of EINVAL to return
  an error for bad arguments (such as invalid counts for bread and bwrite).
- Map SMB bus error bits to EIO in smbus_error().
- Make the smbus driver call bus_generic_probe() and require child drivers
  such as smb(4) to create device_t's via identify routines.  Previously,
  smbus just created one anonymous device during attach, and if you had
  multiple drivers that could attach it was just random chance as to which
  driver got to probe for the sole device_t first.
- Add a mutex to the smbus(4) softc and use it in place of dummy splhigh()
  to protect the 'owner' field and perform necessary synchronization for
  smbus_request_bus() and smbus_release_bus().
- Change the bread() and bwrite() methods of alpm(4), amdpm(4), and
  viapm(4) to only perform a single transaction and not try to use a
  loop of multiple transactions for a large request.  The framing and
  commands to use for a large transaction depend on the upper-layer
  protocol (such as SSIF for IPMI over SMBus) from what I can tell, and the
  smb(4) driver never allowed bulk read/writes of more than 32-bytes
  anyway.  The other smb drivers only performed single transactions.
- Fix buffer overflows in the bread() methods of ichsmb(4), alpm(4),
  amdpm(4), amdsmb(4), intpm(4), and nfsmb(4).
- Use SMB_xxx errors in viapm(4).
- Destroy ichsmb(4)'s mutex after bus_generic_detach() to avoid problems
  from child devices making smb upcalls that would use the mutex during
  their detach methods.

a5f50ef9e4 netchild's mega-patch to isolate compiler dependencies into a central
place.

This moves the dependency on GCC's and other compiler's features into
the central sys/cdefs.h file, while the individual source files can
then refer to #ifdef __COMPILER_FEATURE_FOO where they by now used to
refer to #if __GNUC__ > 3.1415 && __BARC__ <= 42.

By now, GCC and ICC (the Intel compiler) have been actively tested on
IA32 platforms by netchild.  Extension to other compilers is supposed
to be possible, of course.

a122cca953 These are changes to allow to use the Intel C/C++ compiler (lang/icc)

Most of the changes are just adding __INTEL_COMPILER to #ifdef's, as
icc v8 may define __GNUC__ some parts may look strange but are
necessary.

Additional changes:

     The entire checksum code should IMHO be replaced with the DragonFly

Incarnations of this patch survive gcc compiles since a loooong time,

(exceptions: snd_* if used as modules), it survives a build of the
entire ports collection with icc.
