From: Aman Dhoot <amandhoot12@gmail.com>

[ Upstream commit ac5408991ea6b06e29129b4d4861097c4c3e0d59 ]

The device works fine in native RMI mode, there is no reason to use legacy
PS/2 mode with it.

[PATCH AUTOSEL 4.19 02/11] serial: 8250: 8250_omap: Avoid RS485 RTS glitch on ->set_termios()

[Sasha Levin]

From: Lukas Wunner <lukas@wunner.de>

[ Upstream commit 038ee49fef18710bedd38b531d173ccd746b2d8d ]

RS485-enabled UART ports on TI Sitara SoCs with active-low polarity
exhibit a Transmit Enable glitch on ->set_termios():

omap8250_restore_regs(), which is called from omap_8250_set_termios(),
sets the TCRTLR bit in the MCR register and clears all other bits,
including RTS.  If RTS uses active-low polarity, it is now asserted
for no reason.

The TCRTLR bit is subsequently cleared by writing up->mcr to the MCR
register.  That variable is always zero, so the RTS bit is still cleared
(incorrectly so if RTS is active-high).

(up->mcr is not, as one might think, a cache of the MCR register's
current value.  Rather, it only caches a single bit of that register,
the AFE bit.  And it only does so if the UART supports the AFE bit,
which OMAP does not.  For details see serial8250_do_set_termios() and
serial8250_do_set_mctrl().)

Finally at the end of omap8250_restore_regs(), the MCR register is
restored (and RTS deasserted) by a call to up->port.ops->set_mctrl()
(which equals serial8250_set_mctrl()) and serial8250_em485_stop_tx().

So there's an RTS glitch between setting TCRTLR and calling
serial8250_em485_stop_tx().  Avoid by using a read-modify-write
when setting TCRTLR.

While at it, drop a redundant initialization of up->mcr.  As explained
above, the variable isn't used by the driver and it is already
initialized to zero because it is part of the static struct
serial8250_ports[] declared in 8250_core.c.  (Static structs are
initialized to zero per section 6.7.8 nr. 10 of the C99 standard.)

[PATCH AUTOSEL 4.19 07/11] tcp: configurable source port perturb table size

[Sasha Levin]

From: Gleb Mazovetskiy <glex.spb@gmail.com>

[ Upstream commit aeac4ec8f46d610a10adbaeff5e2edf6a88ffc62 ]

On embedded systems with little memory and no relevant
security concerns, it is beneficial to reduce the size
of the table.

Reducing the size from 2^16 to 2^8 saves 255 KiB
of kernel RAM.

Makes the table size configurable as an expert option.

The size was previously increased from 2^8 to 2^16
in commit 4c2c8f03a5ab ("tcp: increase source port perturb table to
2^16").

[PATCH AUTOSEL 4.19 11/11] dm integrity: flush the journal on suspend

[Sasha Levin]

From: Mikulas Patocka <mpatocka@redhat.com>

[ Upstream commit 5e5dab5ec763d600fe0a67837dd9155bdc42f961 ]

This commit flushes the journal on suspend. It is prerequisite for the
next commit that enables activating dm integrity devices in read-only mode.

Note that we deliberately didn't flush the journal on suspend, so that the
journal replay code would be tested. However, the dm-integrity code is 5
years old now, so that journal replay is well-tested, and we can make this
change now.
