The numbering is just so I can apply the patches in the right order 
with a for loop in the packaging script. The missing 7* was the 
experimental patches we tried which moved has_fpu in the thread_info 
struct (which did not work).

The patchset is simply made of:

4903062b5485f0e2c286a23b44c9b59d9b017d53: this one requires a slight 
modification:
-#define safe_address (kstat_cpu(0).cpustat.user)
instead of:
-#define safe_address 
(__get_cpu_var(kernel_cpustat).cpustat[CPUTIME_USER])
