Question about the segment [[ 60000fff80000000-60000fff80004000 rw-p 0000000000000000 00:00 0 ]]

Hello All,

I found the following segment in all the process's on IA64 linux kernel.

60000fff80000000-60000fff80004000 rw-p 0000000000000000 00:00 0 (just
above the stack).

Was wondering what excatly is there in this segment? Does it have any
information about the file descriptors /open file table ?

I have a code which tries to override this segment but once I override
this the program gets corrupted.

Also why IPF kernel differs from other systems where the mmap space is
below &_etext where as on other systems its above &_end. ??

Looking forward to hear from you.
Best,
Vamsi
