Integrate the PTI Global bit fixes which conflict with the 32bit PTI
support.
Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

The kernel image is mapped into two places in the virtual address space
(addresses without KASLR, of course):
1. The kernel direct map (0xffff880000000000)
2. The "high kernel map" (0xffffffff81000000)
We actually execute out of #2. If we get the address of a kernel symbol,
it points to #2, but almost all physical-to-virtual translations point to
Parts of the "high kernel map" alias are mapped in the userspace page
tables with the Global bit for performance reasons. The parts that we map
to userspace do not (er, should not) have secrets. When PTI is enabled then
the global bit is usually not set in the high mapping and just used to
compensate for poor performance on systems which lack PCID.
This is fine, except that some areas in the kernel image that are adjacent
to the non-secret-containing areas are unused holes. We free these holes
back into the normal page allocator and reuse them as normal kernel memory.
The memory will, of course, get *used* via the normal map, but the alias
mapping is kept.
This otherwise unused alias mapping of the holes will, by default keep the
Global bit, be mapped out to userspace, and be vulnerable to Meltdown.
Remove the alias mapping of these pages entirely. This is likely to
fracture the 2M page mapping the kernel image near these areas, but this
should affect a minority of the area.
The pageattr code changes *all* aliases mapping the physical pages that it
operates on (by default). We only want to modify a single alias, so we
need to tweak its behavior.
This unmapping behavior is currently dependent on PTI being in place.
Going forward, we should at least consider doing this for all
configurations. Having an extra read-write alias for memory is not exactly
ideal for debugging things like random memory corruption and this does
undercut features like DEBUG_PAGEALLOC or future work like eXclusive Page
Frame Ownership (XPFO).

Since mountpoint crossing can happen without leaving lazy mode,
root dentries do need the same protection against having their
memory freed without RCU delay as everything else in the tree.
It's partially hidden by RCU delay between detaching from the
mount tree and dropping the vfsmount reference, but the starting
point of pathwalk can be on an already detached mount, in which
case umount-caused RCU delay has already passed by the time the
lazy pathwalk grabs rcu_read_lock(). If the starting point
happens to be at the root of that vfsmount *and* that vfsmount
covers the entire filesystem, we get trouble.

When btrfs hits error after modifying fs_devices in
btrfs_init_new_device() (such as btrfs_add_dev_item() returns error), it
leaves everything as is, but frees allocated btrfs_device. As a result,
fs_devices->devices and fs_devices->alloc_list contain already freed
btrfs_device, leading to later use-after-free bug.
Error path also messes the things like ->num_devices. While they go back
to the original value by unscanning btrfs devices, it is safe to revert
them here.

It's entirely possible that a crafted btrfs image contains overlapping
chunks.
Although we can't detect such problem by tree-checker, it's not a
catastrophic problem, current extent map can already detect such problem
and return -EEXIST.
We just only need to exit gracefully and fail the mount.

A crafted btrfs image with incorrect chunk<->block group mapping will
trigger a lot of unexpected things as the mapping is essential.
Although the problem can be caught by block group item checker
added in "btrfs: tree-checker: Verify block_group_item", it's still not
sufficient. A sufficiently valid block group item can pass the check
added by the mentioned patch but could fail to match the existing chunk.
This patch will add extra block group -> chunk mapping check, to ensure
we have a completely matching (start, len, flags) chunk for each block
group at mount time.
Here we reuse the original helper find_first_block_group(), which is
already doing the basic bg -> chunk checks, adding further checks of the
start/len and type flags.

When doing an incremental send, if we have a file in the parent snapshot
that has prealloc extents beyond EOF and in the send snapshot it got a
hole punch that partially covers the prealloc extents, the send stream,
when replayed by a receiver, can result in a file that has a size bigger
than it should and filled with zeroes past the correct EOF.
For example:
$ mkfs.btrfs -f /dev/sdb
$ mount /dev/sdb /mnt
$ xfs_io -f -c "falloc -k 0 4M" /mnt/foobar
$ xfs_io -c "pwrite -S 0xea 0 1M" /mnt/foobar
$ btrfs subvolume snapshot -r /mnt /mnt/snap1
$ btrfs send -f /tmp/1.send /mnt/snap1
$ xfs_io -c "fpunch 1M 2M" /mnt/foobar
$ btrfs subvolume snapshot -r /mnt /mnt/snap2
$ btrfs send -f /tmp/2.send -p /mnt/snap1 /mnt/snap2
$ stat --format %s /mnt/snap2/foobar
1048576
$ md5sum /mnt/snap2/foobar
d31659e82e87798acd4669a1e0a19d4f /mnt/snap2/foobar
$ umount /mnt
$ mkfs.btrfs -f /dev/sdc
$ mount /dev/sdc /mnt
$ btrfs receive -f /mnt/1.snap /mnt
$ btrfs receive -f /mnt/2.snap /mnt
$ stat --format %s /mnt/snap2/foobar
3145728
# --> should be 1Mb and not 3Mb (which was the end offset of hole
# punch operation)
$ md5sum /mnt/snap2/foobar
117baf295297c2a995f92da725b0b651 /mnt/snap2/foobar
# --> should be d31659e82e87798acd4669a1e0a19d4f as in the original fs
This issue actually happens only since commit ffa7c4296e93 ("Btrfs: send,
do not issue unnecessary truncate operations"), but before that commit we
were issuing a write operation full of zeroes (to "punch" a hole) which
was extending the file size beyond the correct value and then immediately
issue a truncate operation to the correct size and undoing the previous
write operation. Since the send protocol does not support fallocate, for
extent preallocation and hole punching, fix this by not even attempting
to send a "hole" (regular write full of zeroes) if it starts at an offset
greater then or equals to the file's size. This approach, besides being
much more simple then making send issue the truncate operation, adds the
benefit of avoiding the useless pair of write of zeroes and truncate
operations, saving time and IO at the receiver and reducing the size of
the send stream.
A test case for fstests follows soon.

on-disk devs stats value is updated in btrfs_run_dev_stats(),
which is called during commit transaction, if device->dev_stats_ccnt
is not zero.
Since current replace operation does not touch dev_stats_ccnt,
on-disk dev stats value is not updated. Therefore "btrfs device stats"
may return old device's value after umount/mount
(Example: See "btrfs ins dump-t -t DEV $DEV" after btrfs/100 finish).
Fix this by just incrementing dev_stats_ccnt in
btrfs_dev_replace_finishing() when replace is succeeded and this will
update the values.
