[uml-devel] TLS patches compilation fixups

[uml-devel] TLS patches compilation fixups

[Blaisorblade]

I've taken TLS patches from Jeff Dike's tree today, and made them compile in 
all SKAS/TT configurations. The errors were easy to fix, however (ever 
because I still remember my code and the comments help).

Btw, D.Bahi, your fixup patch was a bit bogus (doesn't matter when not using 
TT, however).

I've taken (and made apply) these ones:
global-ldt-sem
uml-tls-support-sc-tables
uml-clean-arch_switch
uml-add-tls-support
uml-add-tls-support-flush-empty

And added, on top of them, these ones:

fix-struct-compile (to say user_desc instead of modify_ldt_ldt_s. Will break 
on 2.4 kernel headers on the host)
compile-tt-off-indirect-set-thread-area (make the indirect_* thing compile)
remove-indirect-set-thread-area (remove that thing - should be safe it seems)

I intentionally removed "uml-add-tls-support-debug", as it's debug-only stuff 
IMHO and was used to try to make it work (IIRC).

It never works, it seems, I should check if sometimes it succeeds, indeed, I'm 
doing that with "uml-add-tls-support-debug-check-never-works" (not tested 
yet, don't run yourself unless you really want).

I hadn't written SKAS0 support when I wrote the patches, and they show it 
hasn't been added.

I will shortly publish all the updated patches (against vanilla 2.6.15) under:

http://www.user-mode-linux.org/~blaisorblade/patches/devel-guest/uml-2.6.15-tls-1

in the usual combo + splitout + signature form.
