There are two such limitations when using a PAE kernel and 32bit user
space on x86-64, which are the same limitations on P6 class CPUs:
1. 64GB maximum physical memory
2. 2GB per process address space
~99.9999% of desktop Linux users will never exceed either of these.
The
same number of users have less than 64GB physical memory. For those
who
have trouble with percentages, this is 1 in a million users.
