Manage the VMAs with SRCU such that we can do a lockless VMA lookup.
We put the fput(vma-vm_file) in the SRCU callback, this keeps files
valid during speculative faults, this is possible due to the delayed
fput work by Al Viro -- do we need srcu_barrier() in unmount
someplace?
We guard the mm_rb
One of the side effects of speculating on faults (without holding
mmap_sem) is that we can race with free_pgtables() and therefore we
cannot assume the page-tables will stick around.
Remove the relyance on the pte pointer.

Why not?
I'm trying to put root filesystem on nfs, without
initrd/initramfs. Thus no modules for me.

Sending in a sec.
Also, this is
Wrap the VMA modifications (vma_adjust/unmap_page_range) with sequence
counts such that we can easily test if a VMA is changed.
The unmap_page_range() one allows us to make assumptions about
page-tables; when we find the seqcount hasn't changed we can assume
page-tables are still valid.

Hi,
I figured I'd give my 2010 speculative fault series another spin:
https://lkml.org/lkml/2010/1/4/257
Since then I think many of the outstanding issues have changed sufficiently to
warrant another go. In particular Al Viro's delayed fput seems to have made it
entirely 'normal' to delay
Provide infrastructure to do a speculative fault (not holding
mmap_sem).
The not holding of mmap_sem means we can race against VMA
change/removal and page-table destruction. We use the SRCU VMA freeing
to keep the VMA around. We use the VMA seqcount to detect change
(including umapping /
When speculating faults (without holding mmap_sem) we need to validate
that the vma against which we loaded pages is still valid when we're
ready to install the new PTE.
Therefore, replace the pte_offset_map_lock() calls that (re)take the
PTL with pte_map_lock() which can fail in case we find the
LSL is faster than RDTSCP and works everywhere; there's no need to
switch between them depending on CPU.

This replaces patch 8 from v1. Changes from v1:
- Use LSL unconditionally (drop static_cpu_has).

When trying to develop a custom format handler, the errors returned all
effectively get bucketed as EINVAL with no kernel messages. The other
errors (ENOMEM/EFAULT) are internal/obvious and basic. Thus any time a
bad handler is rejected, the developer has to walk the dense code and
try to guess
Clean up various coding style issues that checkpatch complains about.
