Sorry for the delay.

I applied your 2 patches to linus-tree, compile and run, when I run
the same UML binary inside UML, I got:

Locating the bottom of the address space ... do_syscall_stub : ret =
-13, offset = 1052680, data = 0a98a008
do_syscall_stub: syscall 192 failed, return value = 0xfffffff3,
expected return value = 0x0
 syscall parameters: 0x0 0x1000 0x7 0x11 0x3 0x19c0
Failed to flush page for address 0x0
Killed

I don't have enough time to dig this, would like to have a look at it?

Thanks.
