In trying to compile OpenAFS, I've run into an error compiling the
loadable kernel module. It appears to be due to the fact that
rc.sysinit does not setup a correct /boot/kernel.h at startup.
In particular, definitions for __BOOT_KERNEL_ENTERPRISE,
__BOOT_KERNEL_UP, and __BOOT_KERNEL_SMP are missing. Also, it
appears that /usr/include/linux/rhconfig.h does not match
/usr/src/linux-2.2.18/include/linux/rhconfig.h (in the latter,
the s390 defs in the former seem to be left out).
The code in rc.sysinit to correctly set these values is bypassed
by a test for the architecture being "s390". Removing this test
wouldn't help, because the next few statements that set KERNEL_TYPE,
etc won't work, because of the peculiar form of the uname string in the
s390 version (with vrdr, SMP instead of smp, etc).
My questions are these:
1) Is there any reason that /usr/include/linux/rhconfig.h and
/usr/src/linux-2.2.18/include/linux/rhconfig.h should not
match exactly? (They do on the Intel version of RedHat 7.0
except for one statement).
Would making them match cause problems building the kernel
or other kernel modules?
2) Does rc.sysinit need to be corrected to properly detect and
set __BOOT_KERNEL_ENTERPRISE, __BOOT_KERNEL_UP and __BOOT_KERNEL_SMP
or are these being properly set somewhere else? It looks like
not setting __BOOT_KERNEL_SMP in particular could generate a
problem. On my system, the kernel's been built for SMP, but
if the __BOOT_KERNEL_SMP define is not set, perhaps modules
are being incorrectly generated for non-SMP operation?
