Description Don Zickus 2010-05-10 15:58:26 UTC
Description of problem:

Using a kernel xen config to compile produces a huge amount of compiler
warnings, such that it makes it hard to see if any changes my patch created
causes any new warnings.

The warning is

include/asm/mach-xen/asm/pgtable.h: In function ‘pud_present’:
include/asm/mach-xen/asm/pgtable.h:102: warning: ‘pud_val’ is static but
used in inline function ‘pud_present’ which is not static

A simple fix corrects the problem and life is happy again.

Detailed testing feedback is always welcomed.

Comment 8 Petr Beňas 2010-12-14 14:30:30 UTC
Verified in 2.6.18-212.el5. 
Compiling kernel with xen config, no warning looking like the one from bug description is printed. Although compiling -211.el5 kernel does not reproduce.
Also verified the patch went to 212.el5.
