The kernel has this really nice facility where if you put "initcall_debug"
on the kernel commandline, it'll print which function it's going to
execute just before calling an initcall, and then after the call completes
it will
1) print if it had an error code
2) checks for a few simple bugs (like leaving irqs off)
and
3) print how long the init call took in milliseconds.
While trying to optimize the boot speed of my laptop, I have been loving
number 3 to figure out what to optimize... ... and then I wished that
the same thing was done for module loading.
This patch makes the module loader use this exact same functionality; it's
a logical extension in my view (since modules are just sort of late
binding initcalls anyway) and so far I've found it quite useful in finding
where things are too slow in my boot.

In the change in commit 09a05394fe, I
overlooked two nits in the logic and this broke using CLONE_PTRACE
when PTRACE_O_TRACE* are not being used.
A parent that is itself traced at all but not using PTRACE_O_TRACE*,
using CLONE_PTRACE would have its new child fail to be traced.
A parent that is not itself traced at all that uses CLONE_PTRACE
(which should be a no-op in this case) would confuse the bookkeeping
and lead to a crash at exit time.
This restores the missing checks and fixes both failure modes.

include/linux/pci.h:673: error: (Each undeclared identifier is reported only once
include/linux/pci.h:673: error: for each function it appears in.)
Sam says:
The problem is that u_ether.o is used by two modules so when we build it
KBUILD_MODNAME is not defined because kbuild does not know what value to
use.
And in pci.h we have the following inline:
static inline int __must_check pci_register_driver(struct pci_driver *driver)
{
return __pci_register_driver(driver, THIS_MODULE, KBUILD_MODNAME);
}
And alpha uses dma-mapping.h to nullify a number of functions that seem to
require something from pci.h.
Making it a macro fixes this particular problem. However, the underlying issue
of a file using KBUILD_MODNAME and being shared between multiple modules is
*not* addressed. I guess the answer there is "don't do that".

I have a new PCI-E radeon RV380 series card (PCI device ID 5b64) that
hangs in my sparc64 boxes when the init scripts set the font. The problem
goes away if I disable acceleration.
I haven't figured out that bug yet, but along the way I found some
corrections to make based upon some auditing.
1) The RB2D_DC_FLUSH_ALL value used by the kernel fb driver
and the XORG video driver differ. I've made the kernel
match what XORG is using.
2) In radeonfb_engine_reset() we have top-level code structure
that roughly looks like:
if (family is 300, 350, or V350)
do this;
else
do that;
...
if (family is NOT 300, OR
family is NOT 350, OR
family is NOT V350)
do another thing;
this last conditional makes no sense, is always true,
and obviously was likely meant to be "family is NOT
300, 350, or V350". So I've made the code match the
intent.
