So you mean the 64-bit grep should see the same cpuinfo as its father process which is 32-bit? For 32-bit process running on 64-bit kernel, we have to explicitly call the personality syscall to get the right cpuinfo, but how to deal with the old 32-bit binaries?
Yes, you could use the syscall to switch the personality. Alternately, you could run "linux32" command to switch the personality to PER_LINUX32 and then execute 64/32 bit applications. Suzuki
