Input: i8042 - enable MUX on Sony VAIO VGN-CS series to fix touchpad

2018-04-08T12:29:52Z

commit 04bb1719c4de94700056241d4c0fe3c1413f5aff upstream. The touch sensor buttons on Sony VAIO VGN-CS series laptops (e.g. VGN-CS31S) are a separate PS/2 device. As the MUX is disabled for all VAIO machines by the nomux blacklist, the data from touch sensor buttons and touchpad are combined. The protocol used by the buttons is probably similar to the touchpad protocol (both are Synaptics) so both devices get enabled. The controller combines the data, creating a mess which results in random button clicks, touchpad stopping working and lost sync error messages: psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 4 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 psmouse serio1: issuing reconnect request Add a new i8042_dmi_forcemux_table whitelist with VGN-CS. With MUX enabled, touch sensor buttons are detected as separate device (and left disabled as there's currently no driver), fixing all touchpad problems.

Input: i8042 - add Lenovo ThinkPad L460 to i8042 reset list

2018-04-08T12:29:52Z

commit b56af54ac78c54a519d82813836f305d7f76ef27 upstream. Reset i8042 before probing because of insufficient BIOS initialisation of the i8042 serial controller. This makes Synaptics touchpad detection possible. Without resetting the Synaptics touchpad is not detected because there are always NACK messages from AUX port.

vfs: do bulk POLL* -> EPOLL* replacement

2018-02-11T22:34:03Z

This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^$[^\"]*$$\$/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro Signed-off-by: Linus Torvalds

Input: hp_sdc - convert to ktime_get()

2018-01-02T05:39:12Z

This gets rid of the deprecated do_gettimeofday() call in favor of ktime_get(), which is also more reliable as it uses monotonic times. The code now gets a bit simpler. Signed-off-by: Arnd Bergmann Patchwork-Id: 10076621 Signed-off-by: Dmitry Torokhov

Input: hil_mlc - convert timeval to jiffies

2018-01-02T05:39:12Z

struct timeval is not y2038 safe, and what mlc->instart do is scheduling a task in a fixed timeout, so jiffies is the simplest choice here. In hilse_donode(), the expires in mod_timer equals jiffies + intimeout - (now - instart) If we use jiffies in 'now', the expires equals instart + intimeout So, all we need to do is that making sure expires is a future timestamp before passed it to mod_timer.

Input: hil_mlc - convert timeval to time64_t

2018-01-02T05:39:12Z

Since mlc->lcv_t is only interested in seconds, directly using time64_t here. This gets rid of the deprecated do_gettimeofday() and avoids problems with time going backwards since we now use the monotonic clocksource.
