Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus
* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus: [MIPS] Fix wrong checksum calculation on 64-bit MIPS [MIPS] VPE loader: Initialize lists before they're actually being used ... [MIPS] Fix reported amount of freed memory - it's in kB not bytes [MIPS] vr41xx: need one more nop with mtc0_tlbw_hazard() [MIPS] SMTC: Fix module build by exporting symbol [MIPS] SMTC: Fix TLB sizing bug for TLB of 64 >= entries [MIPS] Fix APM build [MIPS] There is no __GNUC_MAJOR__
