You sent it and I applied your patch on February 21. Old mail appended below again for Trevor's reference. It doesn't explain why he sees 64-bit values though. Trevor, what kernel exactly are you running?

This is the mips64 version of the patch. A very similar patch could be constructed for ia64... it's very obvious what to do, so I'll leave it to you ia64 people :) Cheers, Andrew diff -u -r1.42.2.23 linux32.c --- arch/mips64/kernel/linux32.c 23 Jan 2003 02:12:59 -0000 1.42.2.23 +++ arch/mips64/kernel/linux32.c 20 Feb 2003 00:05:41 -0000 @@ -672,8 +672,11 @@ u32 bufferram; u32 totalswap; u32 freeswap; - unsigned short procs; - char _f[22]; + u16 procs; + u32 totalhigh; + u32 freehigh; + u32 mem_unit; + char _f[8]; }; extern asmlinkage int sys_sysinfo(struct sysinfo *info); @@ -698,6 +701,9 @@ err |= __put_user (s.totalswap, &info->totalswap); err |= __put_user (s.freeswap, &info->freeswap); err |= __put_user (s.procs, &info->procs); + err |= __put_user (s.totalhigh, &info->totalhigh); + err |= __put_user (s.freehigh, &info->freehigh); + err |= __put_user (s.mem_unit, &info->mem_unit); if (err) return -EFAULT; return ret;
