We can/should try to remove this in a subsequent patch. This should preserve the old gtt init behavior which upon writing these patches seems incorrect. The next patch will fix these things. The one exception is VLV which doesn't have the preserved flush control write behavior. Since we want to do that for all GEN6+ stuff, we'll handle that in a later patch. Mainstream VLV support doesn't actually exist yet anyway. v2: Update the comment to remove the "voodoo" Check that the last pte written matches what we readback v3: actually kill cache_level_to_agp_type since most of the flags will disappear in an upcoming patch v4: v3 was actually not what we wanted (Daniel) Make the ggtt bind assertions better and stricter (Chris) Fix some uncaught errors at gtt init (Chris) Some other random stuff that Chris wanted v5: check for i==0 in gen6_ggtt_bind_object to shut up gcc (Ben) Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Reviewed-by [v4]: Chris Wilson <chris@chris-wilson.co.uk> [danvet: Make the cache_level -> agp_flags conversion for pre-gen6 a tad more robust by mapping everything != CACHE_NONE to the cached agp flag - we have a 1:1 uncached mapping, but different modes of cacheable (at least on later generations).

| * drm: extract dp link train delay functions from radeonDaniel Vetter2012-10-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This requires a few changes since that dpcd value is above the range currently cached by radeon. I've check the dp specs, and above 0xf there's a big gap and nothing that looks like we should cache it while a given device is plugged in. It's also the same value that i915.ko uses. Hence extend the various dpcd arrays in the radeon driver, use proper symbolic constants where applicable (one place overallocated the dpcd array to 25 bytes). Then also drop the rd_interval cache - radeon_dp_link_train_init re-reads the dpcd block, so the values we'll consume in train_cr and train_ce will always be fresh. To avoid needless diff-churn, #define the old size of dpcd as the new one and keep it around. v2: Alex Deucher noticed one place where I've forgotten to replace 8 with DP_RECEIVER_CAP_SIZE.

| * | drm/i915: Allow DRM_ROOT_ONLY|DRM_MASTER to submit privileged batchbuffersChris Wilson2012-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the introduction of per-process GTT space, the hardware designers thought it wise to also limit the ability to write to MMIO space to only a "secure" batch buffer. The ability to rewrite registers is the only way to program the hardware to perform certain operations like scanline waits (required for tear-free windowed updates). So we either have a choice of adding an interface to perform those synchronized updates inside the kernel, or we permit certain processes the ability to write to the "safe" registers from within its command stream. This patch exposes the ability to submit a SECURE batch buffer to DRM_ROOT_ONLY|DRM_MASTER processes. v2: Haswell split up bit8 into a ppgtt bit (still bit8) and a security bit (bit 13, accidentally not set). Also add a comment explaining why secure batches need a global gtt binding.

If instead we were using the generic one (which ends up being xen_flush_tlb) we end up making the MMUEXT_TLB_FLUSH_LOCAL hypercall. But before we make that hypercall the kernel will IPI all of the vCPUs (even those that were asleep from the hypervisor perspective). The end result is that we needlessly wake them up and do a TLB flush when we can just let the hypervisor do it correctly. This patch gives around 50% speed improvement when migrating idle guest's from one host to another.

This is an optimization. The RCU-protected region is very small, so there will be no latency problems if we disable preempt in this region. So we use rcu_read_lock_sched / rcu_read_unlock_sched that translates to preempt_disable / preempt_disable. It is smaller (and supposedly faster) than preemptible rcu_read_lock / rcu_read_unlock.

This patch fixes a bug in percpu-rw-semaphores where a barrier was missing in percpu_up_write. This patch improves performance on the read path of percpu-rw-semaphores: on non-x86 cpus, there was a smp_mb() in percpu_up_read.

A clean rearchitecturing of the code is in the works - meanwhile these are reverts that restore the best-known-working state of the kernel. There's also EFI fixes and other small fixes." * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, mm: Undo incorrect revert in arch/x86/mm/init.c x86: efi: Turn off efi_enabled after setup on mixed fw/kernel x86, mm: Find_early_table_space based on ranges that are actually being mapped x86, mm: Use memblock memory loop instead of e820_RAM x86, mm: Trim memory in memblock to be page aligned x86/irq/ioapic: Check for valid irq_cfg pointer in smp_irq_move_cleanup_interrupt x86/efi: Fix oops caused by incorrect set_memory_uc() usage x86-64: Fix page table accounting Revert "x86/mm: Fix the size calculation of mapping tables" MAINTAINERS: Add EFI git repository location

Also we will use for_each_mem_pfn_range() to loop to map memory range to keep them consistent.
