drm/msm: refactor how we handle vram carveout buffers
Pull some of the logic out into msm_gem_new() (since we don't need to
care about the imported-bo case), and don't defer allocating pages. The
latter is generally a good idea, since if we are using VRAM carveout to
allocate contiguous buffers (ie. no IOMMU), the allocation is more
likely to fail. So failing at allocation time is a more sane option.
Plus this simplifies things in the next patch.

drm/msm: gpu: Enable zap shader for A5XX
The A5XX GPU powers on in "secure" mode. In secure mode the GPU can
only render to buffers that are marked as secure and inaccessible
to the kernel and user through a series of hardware protections. In
practice secure mode is used to draw things like a UI on a secure
video frame.
In order to switch out of secure mode the GPU executes a special
shader that clears out the GMEM and other sensitve registers and
then writes a register. Because the kernel can't be trusted the
shader binary is signed and verified and programmed by the
secure world. To do this we need to read the MDT header and the
segments from the firmware location and put them in memory and
present them for approval.
For targets without secure support there is an out: if the
secure world doesn't support secure then there are no hardware
protections and we can freely write the SECVID_TRUST register from
the CPU. We don't have 100% confidence that we can query the
secure capabilities at run time but we have enough calls that
need to go right to give us some confidence that we're at least doing
something useful.
Of course if we guess wrong you trigger a permissions violation
which usually ends up in a system crash but thats a problem
that shows up immediately.

- Preliminary work to deal with dual-pipeline SoCs (A10, A20, A31, H3,

dual-pipelines bindings. This will be useful to enable the display

This is due to async pf was injected to L2 which should be injected to L1,
L2 guest starts receiving pagefault w/ bogus %cr2(apf token from the host

excessive checks in ufs_write_failed() and ufs_evict_inode()
As it is, short copy in write() to append-only file will fail

Btrfs: fix delalloc accounting leak caused by u32 overflow
btrfs_calc_trans_metadata_size() does an unsigned 32-bit multiplication,
which can overflow if num_items >= 4 GB / (nodesize * BTRFS_MAX_LEVEL * 2).
For a nodesize of 16kB, this overflow happens at 16k items. Usually,
num_items is a small constant passed to btrfs_start_transaction(), but
we also use btrfs_calc_trans_metadata_size() for metadata reservations
for extent items in btrfs_delalloc_{reserve,release}_metadata().
In drop_outstanding_extents(), num_items is calculated as
inode->reserved_extents - inode->outstanding_extents. The difference
between these two counters is usually small, but if many delalloc
extents are reserved and then the outstanding extents are merged in
btrfs_merge_extent_hook(), the difference can become large enough to
overflow in btrfs_calc_trans_metadata_size().
The overflow manifests itself as a leak of a multiple of 4 GB in
delalloc_block_rsv and the metadata bytes_may_use counter. This in turn
can cause early ENOSPC errors. Additionally, these WARN_ONs in
extent-tree.c will be hit when unmounting:
Fix it by casting nodesize to a u64 so that
btrfs_calc_trans_metadata_size() does a full 64-bit multiplication.
While we're here, do the same in btrfs_calc_trunc_metadata_size(); this
can't overflow with any existing uses, but it's better to be safe here
than have another hard-to-debug problem later on.
