Hi Linus,
Been a bit busy, first week of kids school, and waiting on other trees to go in before I could send this, so its a bit later than I'd normally like.
For some reason the request-pull and the merge into your tree look different,
since some of the changes in this have already gone in via the arm-soc tree
and dma stuff, all for tegra. Hopefully nobody rebased when they shouldn't.
Highlights:
core: timestamp fixes, lots of misc cleanups
new drivers: bochs virtual vga
vmwgfx: major overhaul for their nextgen virt gpu.
i915: runtime D3 on HSW, watermark fixes, power well work, fbc fixes, bdw is no longer prelim.
nouveau: gk110/208 acceleration, more pm groundwork, old overlay support
radeon: dpm rework and clockgating for CIK, pci config reset, big endian fixes
tegra: panel support and DSI support, build as module, prime.
armada, omap, gma500, rcar, exynos, mgag200, cirrus, ast: fixes
msm: hdmi support for mdp5
Dave.

Looks more like it's just a few cross-merges, which then ends up
meaning that there are multiple merge-bases and not just one common
ancestor commit.
In that case, a simple "git diff" can't do a great job, and the actual
merge diff will usually end up different.

I suppose the last line should read
ssize_t cur_size = min(size, (size_t) PAGE_SIZE - off);
to silence this. But I haven't tested yet.

drm/i915: stop using GMBUS IRQs on Gen4 chips
back then in 3.9 timeframe, so it might be somehow related. It's, at the
end of the day, again IRQ 16 -- and see the changelog of c12aba5a why this
is rather mysterious (IRQ 16 is assigned to the card when it's not using
MSI, but it *is* in fact using MSI in all the cases).

Daniel, it's your commit this bisects to...
If we end up having to revert, I'd just touch the has_aux_irq part, for
example:

Sorry for missing your report here. Before we disable this again for
gen4 I want to make sure that it's the same irq misrouting issue which
was already the cause for the gmbus irq mess. Can you please boot with
pci=nomsi (so that i915 uses irq16)?
If that's confirmed then I think we should add the same comment we've
added in intel_i2c.c to this code so that no one dares to wake this
dragon again. I'll do that when I commit the fix.
Thanks, Daniel

Confirmed, with MSI disabled, i915 is using IRQ 16 and everything is
working well.

Silence this warning by casting "PAGE_SIZE - off" to size_t. Since
"PAGE_SIZE - off" is between 0 and PAGE_SIZE, and PAGE_SIZE is at most
21 bits wide while size_t is at least 32 bits wide, this should be safe.

Isn't the usual way of dealing with these to do something like
ssize_t cur_size = min_t(ssize_t, size, PAGE_SIZE - off)

I wouldn't know. I did
$ git grep -n "(size_t)(PAGE_SIZE"
arch/powerpc/mm/dma-noncoherent.c:357: size_t seg_size = min((size_t)(PAGE_SIZE - offset), size);
arch/tile/kernel/pci-dma.c:176: size_t bytes = min(size, (size_t)(PAGE_SIZE - offset));
arch/tile/kernel/pci-dma.c:192: size_t bytes = min(size, (size_t)(PAGE_SIZE - offset));
drivers/net/wireless/ti/wlcore/main.c:806: len = min(maxlen, (size_t)(PAGE_SIZE - wl->fwlog_size));
drivers/scsi/libfc/fc_libfc.c:143: (size_t)(PAGE_SIZE - (off & ~PAGE_MASK)));
drivers/target/tcm_fc/tfc_io.c:160: tlen = min(tlen, (size_t)(PAGE_SIZE -
drivers/target/tcm_fc/tfc_io.c:311: tlen = min(tlen, (size_t)(PAGE_SIZE -
and concluded my solution was acceptable. Is your alternative considered
to be better?
