.. small detail, but the silly e1000e initcall warning debugging caused me to look at this code. Rather than gouge my eyes out with a spoon, I just fixed it. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
I noticed that sysctl_check.o was the largest object file in a allnoconfig build in kernel/*. 36243 0 0 36243 8d93 kernel/sysctl_check.o This is because it was default y and && EMBEDDED. But I don't really see a need for a non kernel developer to have their sysctls checked all the time. So move the Kconfig into the kernel debugging section and also drop the default y and the EMBEDDED check.

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.

Given that the init/Kconfig file uses a "menuconfig" directive for modules already, might as well wrap all the submenu entries in an "if" to toss all those dependencies. Signed-off-by: Robert P. J.

commit fb6624ebd912e3d6907ca6490248e73368223da9 (initrd: Fix virtual/physical mix-up in overwrite test) introduced the compiler warning below on mips, as its virt_to_page() doesn't cast the passed address to unsigned long internally, unlike on most other architectures: init/main.c: In function `start_kernel': init/main.c:633: warning: passing argument 1 of `virt_to_phys' makes pointer from integer without a cast init/main.c:636: warning: passing argument 1 of `virt_to_phys' makes pointer from integer without a cast For now, kill the warning by explicitly casting initrd_start to `void *', as that's the type it should really be.
