From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)

Description of problem:
On a system that is either newly installed or has had make mrproper run, when 
High Memory Support is deselected in the kernel and the Maximum Virtual Memory 
is left at the default of 3GB or changed to 1GB, then the kernel compilation 
will fail.  If the max vm is changed to 2GB, the compilation will complete.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.Run make mrproper 
2.Configure the kernel and deselect High Memory Support.
2.Leave Maximum Virtual Memory at the default of 3GB or change to 1GB.
3.Run make install and it will report an error in sched.c
4.If you reconfigure the kernel and change the max virtual memory to 1GB, 
you'll get the same failure, but if it is changed to 2GB, the compilation will 
complete successfully.
	

Actual Results:  If high mem and max VM == 3GB or 1GB, the kernel compilation 
will fail.  If the max VM is set to 2GB, the compilation will complete. 

Expected Results:  The kernel should compile regardless of what the value of 
max VM is.
