Dave Hansen f0d662759a KVM: Reduce kvm stack usage in kvm_arch_vm_ioctl() ... On my machine with gcc 3.4, kvm uses ~2k of stack in a few select functions. This is mostly because gcc fails to notice that the different case: statements could have their stack usage combined. It overflows very nicely if interrupts happen during one of these large uses. This patch uses two methods for reducing stack usage. 1. dynamically allocate large objects instead of putting on the stack. 2. Use a union{} member for all of the case variables. This tricks gcc into combining them all into a single stack allocation.
