compile failure with get_user_asm()

compile failure with get_user_asm()

[Badari Pulavarty]

Hi,

I just updated my systemtap sources & tests and I am not able to
compile systemtap modules anymore.

I reported this to Hien earlier. Hien, do you have a fix for it ?

Thanks,
Badari

The only place in systemtap sources that refers to __get_user_asm is
in <runtime/loc2c-runtime.h>, which suffered no changes since October.
Perhaps the change is more in your kernel than in systemtap.  What is
the declaration of __get_user_asm in your kernel/arch?

Badari,

I posted a patch in this BZ
http://sourceware.org/bugzilla/show_bug.cgi?id=2076

You can try to apply the patch  to the file
/usr/local/share/systemtap/runtime/loc2c-runtime.h

I am going to check the fix sometime later.

Hien.
