perf/x86/amd/brs: Fix kernel address leakage
A user-only branch stack can contain branches that originate from

are in the kernel.

Input: mms114 - fix multi-touch slot corruption
If the touchscreen controller reports a touch ID of 0, the driver
calculates the slot ID as touch->id - 1, which underflows to UINT_MAX.
This is passed to input_mt_slot() as -1.
Since the input core ignores negative slot values, the active slot remains
unchanged. The driver then reports the touch coordinates for the previously
active slot, corrupting its state.
Fix this by rejecting touch reports with ID 0.

dm-bufio: fix wrong count calculation in dm_bufio_issue_discard
block_to_sector converts a block number to a sector number and adds
c->start to the result. It is inappropriate to use this function for
converting the number of blocks to a number to sectors because c->start
would be incorrectly added to the result.
Luckily, the only target that uses dm_bufio_issue_discard is dm-ebs,
which sets c->start to 0, so this bug is latent.

block: remove redundant GD_NEED_PART_SCAN in add_disk_final()
add_disk_final() sets GD_NEED_PART_SCAN before calling bdev_add(),
then calls disk_scan_partitions() which sets the flag itself. The
early set is redundant and introduces a race.
Between bdev_add() and disk_scan_partitions(), concurrent openers
(multipathd, blkid, LVM) see the flag in blkdev_get_whole() and
trigger bdev_disk_changed(). When disk_scan_partitions() then runs,
it calls bdev_disk_changed() again, dropping the partitions the
concurrent opener already created before re-adding them, which can
result in transient partition disappearances.
The race is observable by inserting an msleep() between bdev_add()
and disk_scan_partitions() while running concurrent open() calls
during device bind. Without artificial delay, it manifests under
scheduling pressure during boot on systems with aggressive device
scanners (multipathd, systemd-udevd).

drbd: reject data replies with an out-of-range payload size
recv_dless_read() receives a P_DATA_REPLY from a peer into the bio of an
outstanding read request. The peer-supplied payload length reaches it as
the signed int data_size, and two peer-controlled inputs can make it
negative. With a negotiated data-integrity-alg the digest length is
subtracted first, so a reply whose payload is smaller than the digest
underflows data_size. With no integrity algorithm (the default) data_size
is assigned from the unsigned h95/h100 wire length and drbdd() never
bounds it for a payload-carrying command, so a length above INT_MAX casts
it negative; this path needs no non-default feature. The bio receive loop
then computes expect = min_t(int, data_size, bv_len), which is negative,
and drbd_recv_all_warn(mapped, expect) receives with a size_t of SIZE_MAX
into the first mapped page.
The sibling receive path read_in_block() is not affected: it uses an
unsigned size and rejects it against DRBD_MAX_BIO_SIZE before receiving.
Reject a data reply whose size is negative after the optional digest
subtraction, covering both triggers.
