From arch/um/os-Linux/sys-i386/registers.c:
/* XXX These need to use [GS]ETFPXREGS and copy_sc_{to,from}_user_skas needs
* to pass in a sufficiently large buffer
*/
Could fixing this be the real fix instead of "fp-state" in the incrementals?

It is really difficult for the end-user (and tricky for a developer) to build
a 32-bit UML on a 64-bit host box...
I would like to address this, but I've not definite ideas.
The problems are:
1) how the user must choose what he wants (SUBARCH=i386 can be useful, maybe a
Kconfig option would be

Are you using 2.4? O
Anton, would you test the current -bk tree for the CONFIG_GCOV problem and the
patch I and Jeff put together?

The above should fix the situation for you... for real 3.4 Gcc, however, the
problems are bigge

That one is easy -- just use "linux32 make ...". That will switch the
personality and "uname" will return "i686" instead o
Good day, all,
Charlyn Dike! Jeff and Charlyn were married yesterday in Boston
Mass, USA in a small ceremony near the MIT campus.
The two of them will be traveling for a few weeks. Jeff is
unlikely to be near a good Internet connection for a while, so we should
find our own UML answers until

If I open a device like /dev/loop0 or /dev/console from a hostfs mount, I'll
get the UML device, not the host device, right?
So why are the permissions checks on hostfs devices done relative to the
_host_ user? If /dev/console doesn't belong to the current user, the system
can't even open the

OK after much further investigation, redownloading of source
(2.6.11.4) and looking at what you have said I know why it is

I had assumed (wrongly of course) that ARCH_SYSCALLS was a one line
symbol definition but it is much more than this.
The problem occurs because in both

The other problem with not linking va_copy has been resolved by
changing to __va_copy in skas/uaccess.c. This seems to be a known
problem with older compilers and there is a patch out there but not in
2.6.11 or by the looks of it 2.6.12 rc1 by my reading of the log (nor
