rather 3) I cant find function which oracle calls to manage memory at
0x50000000, this is why I ask for help.
I can only state that linux_mprotect dont called with addr at 0x50000000.

Nov  4 12:40:14 tiger kernel: mprotect: addr:55c00000, len:4096, prot:1,
bsdprot:5, ret:0
Nov  4 12:40:14 tiger kernel: mprotect: addr:55c81000, len:4096, prot:1,
bsdprot:5, ret:0

This are only addresses which are arguments for linux_mprotect.
I have suspected linux_mmap_common but it not called either.
