drm/i915/sdvo: Only set is_lvds if we have a valid fixed mode.
If we have failed to ascertain the fixed mode for the LVDS panel, then
trust the pixel clock ranges reported for the connection when determing
valid modes. This makes intel_sdvo_mode_valid() consistent with
intel_lvds_mode_valid() which is also a no-op is there is no fixed mode
defined. (Since the mode is both validated by SDVO and LVDS, why are
checking against an LVDS fixed mode in SDVO...)
By only defining is_lvds to be true when we actually have an LVDS output
with a fixed mode, we avoid various potential NULL deferences where the
assumption is made that all LVDS outputs have a fixed mode.

Bug 29449 - [Q35] failure to read EDID/vbios for LVDS, no mode => no output
https://bugs.freedesktop.org/show_bug.cgi?id=29449
The primary failure in this bug is not finding the EDID and determining
the correct fixed panel mode. However, this patch should fix the
secondary issue of not enabling any of the standard modes for the panel
either.

drm/i915: Wake-up wait_request() from elapsed hang-check (v2)
If our watchdog fires and we see that the GPU is idle, but that we
are still waiting on an interrupt, forcibly wake-up the waiter.
i915_do_wait_request() should not be racy, yet there are persistent
reports that 945GM hangs whilst the GPU is idle. This implies that the
hardware is not quite as coherent as the documentation claims - a write
followed by a flush is supposed to be coherent in main memory before the
flush is retired and the irq is emitted. This seems to be a sensible and
elegant guard to force the wait to timeout.

why the machine appeared to stall.

drm/i915: Implement fair lru eviction across both rings. (v2)
Based in a large part upon Daniel Vetter's implementation and adapted
for handling multiple rings in a single pass.
This should lead to better gtt usage and fixes the page-fault-of-doom
triggered. The fairness is provided by scanning through the GTT space
amalgamating space in rendering order. As soon as we have a contiguous
space in the GTT large enough for the new object (and its alignment),
evict any object which lies within that space. This should keep more
objects resident in the GTT.
Doing throughput testing on a PineView machine with cairo-perf-trace
indicates that there is very little difference with the new LRU scan,
perhaps a small improvement... Except oddly for the poppler trace.

So add 2nd gen to the list of things that don't like more than

Furthermore I've changed the busy loop into a ringbuffer wait.
Busy-loops that don't check whether the chip died are simply evil.
And performance should actually improve, because there's usually
a decent amount of rendering queued on the gpu, hopefully rendering
that MI_WAIT into a noop by the time it's executed.

nfsd: don't allow setting maxblksize after svc created
It's harmless to set this after the server is created, but also
ineffective, since the value is only used at the time of
svc_create_pooled(). So fail the attempt, in keeping with the pattern
set by write_versions, write_{lease,grace}time and write_recoverydir.
(This could break userspace that tried to write to nfsd/max_block_size
between setting up sockets and starting the server. However, such code
wouldn't have worked anyway, and I don't know of any examples--rpc.nfsd
in nfs-utils, probably the only user of the interface, doesn't do that.)

nfsd: initialize nfsd versions before creating svc
Commit 4e181d9b8c86bf8c0fb90625401d748715f7daec "nfsd: move more into
nfsd_startup()" inadvertently moved nfsd_versions after
nfsd_create_svc(). On older distributions using an rpc.nfsd that does
not explicitly set the list of nfsd versions, this results in
svc-create_pooled() being called with an empty versions array. The
resulting incomplete initialization leads to a NULL dereference in
svc_process_common() the first time a client accesses the server.
Move nfsd_reset_versions() back before the svc_create_pooled(); this
time, put it closer to the svc_create_pooled() call, to make this
mistake more difficult in the future.

pci: fix type warnings in intr_remapping.c
Commit 691aeb97857d ("x86, asm: Clean up and simplify set_64bit()")
sanitized the x86-64 types to set_64bit(), and incidentally resulted in
warnings like
drivers/pci/intr_remapping.c: In function 'modify_irte':
drivers/pci/intr_remapping.c:314: warning: passing argument 1 of 'set_64bit' from incompatible pointer type
arch/x86/include/asm/cmpxchg_64.h:6: note:expected 'volatile u64 *' but argument is of type 'long unsigned int *'
It turns out that the change to set_64bit() really does clean up things,
and the PCI intr_remapping.c file did a rather ugly cast in order to
avoid warnings with the previous set_64bit() type model.
Removing the ugly cast fixes the warning, and makes everybody happy and
expects a set_64bit() to take the logical "u64 *" argument.
