Change fhc(4) to use IRQ numbers instead of RIDs for allocating the
IRQs of children. This works similar to e.g. sbus(4), i.e. add the
IRQ resources as fully specified to the resource lists of the children,
allocate them like normal. When establishing the interrupt search the
interrupt maps of the children for a matching INO to determine which
map we need to write the fully specified interrupt number to and to
enable the mapping (before the RID was used to indicate which interrupt
map to use).
- dev/puc/puc.c:
Revert rev. 1.38, with the above change fhc(4) no longer needs special
treatment for allocating IRQs.
Thanks to: joerg for providing access to an E3500
modulating the STPCLK# pin based on the duty cycle. Since p4tcc uses the
same mechanism (but internal to the CPU), we triggered a hang on some
systems at low frequencies when both were in use. Now, disable
acpi_throttle when p4tcc is also present.

of the stack instead of using malloc, as it's not needed. Many thanks to
LSI for investigating and fixing these problems.

a vlan interface attached to a fxp(4) card when it has not been
initialized yet. We now set the links from our internel TX descriptor
structure to the TX command blocks at attach time rather than at init
time. While I'm here, slightly improve the style in fxp_attach().

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.

Failure to do this will result in following ata_pio_read() calls walking
off the end of the read buffer.
This resolves the "memory modified after free" panics common with Thinkpads

and the X1034A (quad HME; QFE) cards the X1033A (single HME) don't have a
PCI-PCI-bridge so we can't rely on the PCI slot number being useable as
index for the network address to read from the VPD on the latter. Use
the end tag to determine whether it is a QFE VPD with 4 NAs and only use
the slot number as index in this case.

Move usb_get_string() and make it public.
o usbdi.c, bring on par with 1.106, this includes:
- Make an iterator abstraction for looping through all descriptors.
- Whine about not being able to figure out default language if we are debugging.
- Move usb_get_string() and make it public.
o usbdi.h, bring on par with 1.64, this includes:

is particularly useful when VESA is available (either `options VESA'
or load the vesa module), as BIOSes in some notebooks may correctly
save and restore LCD panel settings using VESA in cases where calling
the video BIOS POST is not effective. On some systems it may also
be necessary to set the hw.acpi.reset_video sysctl to 0.
yet I only changed one of them. So when we loaded drivers, we'd fail
to allocate resources correct.
This pointed out that we were doing the wrong thing when we failed to
attach a child. We released all the resources and almost deleted the
child. Instead, we should keep the resources allocated so when/if a
driver is loaded, we can go w/o having to allocate them. We use
pci_cfg_save/restore to restore the BARs with these resources.
This seems to fix the problems that we were seeing that I thought
might have magically gone away in the last revision of cardbus.c (but
really didn't).

Move code to the right location and disallow the use of the 82503
serial mode if the sc->revision field is 0 again. This makes fxp(4)
work correctly with ATMEL 350 93C46 cards (3 port 82559 based with a
82555 PHY), as well as with the older ATMEL 220 93C46 (same flavour)
and with the even older 10Mbps-only 82557 cards with the 82503 serial
interface.
