x86, flags: Rename X86_EFLAGS_BIT1 to X86_EFLAGS_FIXED

2013-06-25T23:25:32+00:00

Bit 1 in the x86 EFLAGS is always set. Name the macro something that actually tries to explain what it is all about, rather than being a tautology. Signed-off-by: H.

lguest: clear cached last cpu when guest_set_pgd() called.

2013-05-08T01:19:18+00:00

commit v3.9-rc1-53-g6d0cda9 "lguest: cache last cpu we ran on." missed one case, which causes a triple fault. The guest calls guest_set_pgd() on the top page, and we carefully remap the Switcher text page. But we didn't reset last_host_cpu, so map_switcher_in_guest() thinks the guest's regs and IDT/GDT etc are already mapped. Reported-by: Paul Bolle Tested-by: Paul Bolle Signed-off-by: Rusty Russell

Merge tag 'virtio-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux

2013-05-02T21:14:04+00:00

Pull virtio & lguest updates from Rusty Russell: "Lots of virtio work which wasn't quite ready for last merge window. Plus I dived into lguest again, reworking the pagetable code so we can move the switcher page: our fixmaps sometimes take more than 2MB now..." Ugh. Annoying conflicts with the tcm_vhost -> vhost_scsi rename. Hopefully correctly resolved. * tag 'virtio-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux: (57 commits) caif_virtio: Remove bouncing email addresses lguest: improve code readability in lg_cpu_start. virtio-net: fill only rx queues which are being used lguest: map Switcher below fixmap. lguest: cache last cpu we ran on. lguest: map Switcher text whenever we allocate a new pagetable. lguest: don't share Switcher PTE pages between guests. lguest: expost switcher_pages array (as lg_switcher_pages). lguest: extract shadow PTE walking / allocating. lguest: make check_gpte et. al return bool. lguest: assume Switcher text is a single page. lguest: rename switcher_page to switcher_pages. lguest: remove RESERVE_MEM constant. lguest: check vaddr not pgd for Switcher protection. lguest: prepare to make SWITCHER_ADDR a variable. virtio: console: replace EMFILE with EBUSY for already-open port virtio-scsi: reset virtqueue affinity when doing cpu hotplug virtio-scsi: introduce multiqueue support virtio-scsi: push vq lock/unlock into virtscsi_vq_done virtio-scsi: pass struct virtio_scsi to virtqueue completion function ...

lguest: rename random32() to prandom_u32()

Use preferable function name which implies using a pseudo-random number generator. Signed-off-by: Akinobu Mita Acked-by: Rusty Russell Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

lguest: map Switcher below fixmap.

2013-04-22T06:15:03+00:00

Now we've adjusted all the code, we can simply set switcher_addr to wherever it needs to go below the fixmaps, rather than asserting that it should be so. With large NR_CPUS and PAE, people were hitting the "mapping switcher would thwack fixmap" message. Reported-by: Paul Bolle Signed-off-by: Rusty Russell

lguest: cache last cpu we ran on.

2013-04-22T06:15:03+00:00

This optimizes the frobbing of our Switcher map. Signed-off-by: Rusty Russell

lguest: map Switcher text whenever we allocate a new pagetable.

2013-04-22T06:15:02+00:00

It's always to same, so no need to put in the PTE every time we're about to run. Keep a flag to track whether the pagetable has the Switcher entries allocated, and when allocating always initialize the Switcher text PTE. Signed-off-by: Rusty Russell
