[uml-devel] tls patch compile problem (syntax error before get_thread_area)

[William S. <wst...@po...>]

Good afternoon, all,
 	While trying to compile 2.6.15 + Jeff's 20060107 patches, I got 
this compile error:

 	By removing the 4 tls related patches (uml-tls-support-sc-tables, 
uml-add-tls-support, uml-add-tls-support-debug, and 
uml-add-tls-support-flush-empty) from series and reapplying, the compile 
continues past this point.  uml-clean-arch_switch also needs to be 
reverted to finish compilation.
 	If it makes a difference, I'm using: gcc version 4.0.2 20051125 
(Red Hat 4.0.2-8).  Finished kernel, config, and System.map are at 
http://www.stearns.org/uml/ (linux-2.6.15-um20060107-notls-2.bz2 and 
friends).
 	Cheers,
 	- Bill
