CVS commit: src/sys

[Mindaugas Rasiukevicius <rmind%netbsd.org@localhost>]

Module Name:    src
Committed By:   rmind
Date:           Thu Jul  9 21:43:17 UTC 2009

Modified Files:
        src/sys/arch/amd64/amd64: vector.S
        src/sys/arch/i386/i386: vector.S
        src/sys/uvm: uvm_emap.c

Log Message:
- Fix rare crashe in the intr_lapic_tlb_bcast() handler: save and setup
  %fs on i386, %gs on amd64 registers, before using them.  Otherwise, it
  might be invalid/garbage, eg. IPI can interrupt userspace.

- Explicitly initialize per-CPU emap generation number.

Thanks <drochner> for reporting and testing of patch.
