Subject: Staging: speakup: Move pasting into a work item
Origin: https://git.kernel.org/cgit/linux/kernel/git/gregkh/staging.git/commit?id=d7500135802ca55b3f4e01a16544e8b34082f8c3
Bug-Debian: https://bugs.debian.org/735202
Bug-Debian: https://bugs.debian.org/744015
Input is handled in softirq context, but when pasting we may
need to sleep. speakup_paste_selection() currently tries to
bodge this by busy-waiting if in_atomic(), but that doesn't
help because the ldisc may also sleep.
For bonus breakage, speakup_paste_selection() changes the
state of current, even though it's not running in process
context.
Move it into a work item and make sure to cancel it on exit.

Subject: Staging: speakup: Update __speakup_paste_selection() tty (ab)usage to
match vt
Origin: https://git.kernel.org/cgit/linux/kernel/git/gregkh/staging.git/commit?id=28a821c306889b9f2c3fff49abedc9b2c743eb73
Bug-Debian: https://bugs.debian.org/735202
Bug-Debian: https://bugs.debian.org/744015
This function is largely a duplicate of paste_selection() in
drivers/tty/vt/selection.c, but with its own selection state. The
speakup selection mechanism should really be merged with vt.
For now, apply the changes from 'TTY: vt, fix paste_selection ldisc
handling', 'tty: Make ldisc input flow control concurrency-friendly',
and 'tty: Fix unsafe vt paste_selection()'.
