On x86-32 at least, CPU_ALLOC_SIZE() returns twice the value that its should. 
For example, CPU_ALLOC_SIZE(8192) returns 2048.  This also causes CPU_ALLOC() to
allocate double the required memory.

Created an attachment (id=3059)
test program

An example run of the attached program demonstrates the problem:

$ ./a.out 8192
CPU_ALLOC_SIZE()=2048

Changed in cvs.
