Not yet. It's on my list, but I haven't had enough round tuits lately.

Title: UML Kernel support for NPTL
Hi,
Did anyone implement the UML kernel support for the NPTL thread library?
Or specifically implemented the set_thread_area system call in UML.
I am interested to boot UML with a rootfs with packages built with a version of glibc that was compiled with

Hi,
When I try gdb-5.3.90 with uml in vanilla-2.6.10 kernel. I found a problem.
When I set a breakpoint somewhere, and after some step, uml will
always get a SIGTRAP signal and trap into gdb.
Does anyone met the same problem as me? Any known fix for it?
thanks!

It is the vsyscall implementation; it's exported by the kernel,

Hi,all:
I found UML only implement its own kernel_thread function but doesn't implement

Then how does UML start a kernel thread in TT mode? Is there any other
functions being called? Thanks a lot!

1) UML includes some of the subarch's (s390) headers. I had to
change one of them with the following one-liner, to make this
