Bug#328183: libc6: Xen and TLS. Patch avaliable
It would be nice to some how include the following in libc6. This would
currently be arch specific to x68 and x68_64.
Xen uses segmentation to provide protection of the memory used for the
hypervisor. This results in some performance issues since wrap-around
segments as used by glibc need expensive extra handling.
It is possible to rebuild glibc so that it only uses segments such
that there is no performance penalty. To do this, you need to apply
the patch below to the glibc sources and then rebuild glibc with the
Patch attached to wiki page above.
