__vdso_gettimeofday on x86 32bit app on 64bit kernel

[Sharath]

hi,

yes, I have fixed both parts of the commit
"37c975545ec63320789962bf307f000f08fabd48".
Actually the changes under "LINUX_2.5 {" was not needed in my case cause
those symbols were not there in base kernel.

These changes seems to be not enough.

Well this is a production env & hence moving to newer version will be
little late.

Thanks
SB
