x86, 8042: Enable A20 using KBC to fix S3 resume on some MSI laptops

2013-01-11T17:03:36Z

commit ad68652412276f68ad4fe3e1ecf5ee6880876783 upstream. Some MSI laptop BIOSes are broken - INT 15h code uses port 92h to enable A20 line but resume code assumes that KBC was used. The laptop will not resume from S3 otherwise but powers off after a while and then powers on again stuck with a blank screen. Fix it by enabling A20 using KBC in i8042_platform_init for x86.

commit 8669cf6793bb38307a30fb6b9565ddc8840ebd3f upstream. On Toshiba Satellite C850D, the touchpad and the keyboard might randomly not work at boot. Preventing MUX mode activation solves this issue. Signed-off-by: Anisse Astier Signed-off-by: Dmitry Torokhov Signed-off-by: Greg Kroah-Hartman

commit 7b125b94ca16b7e618c6241cb02c4c8060cea5e3 upstream. They all define their chassis type as "Other" and therefore are not categorized as "laptops" by the driver, which tries to perform AUX IRQ delivery test which fails and causes touchpad not working.

Revert "tty: make receive_buf() return the amout of bytes received"

2011-06-03T21:33:24Z

This reverts commit b1c43f82c5aa265442f82dba31ce985ebb7aa71c. It was broken in so many ways, and results in random odd pty issues. It re-introduced the buggy schedule_work() in flush_to_ldisc() that can cause endless work-loops (see commit a5660b41af6a: "tty: fix endless work loop when the buffer fills up"). It also used an "unsigned int" return value fo the ->receive_buf() function, but then made multiple functions return a negative error code, and didn't actually check for the error in the caller. And it didn't actually work at all. BenH bisected down odd tty behavior to it: "It looks like the patch is causing some major malfunctions of the X server for me, possibly related to PTYs. For example, cat'ing a large file in a gnome terminal hangs the kernel for -minutes- in a loop of what looks like flush_to_ldisc/workqueue code, (some ftrace data in the quoted bits further down). ... Some more data: It -looks- like what happens is that the flush_to_ldisc work queue entry constantly re-queues itself (because the PTY is full ?) and the workqueue thread will basically loop forver calling it without ever scheduling, thus starving the consumer process that could have emptied the PTY." which is pretty much exactly the problem we fixed in a5660b41af6a. Milton Miller pointed out the 'unsigned int' issue.

it makes it simpler to keep track of the amount of bytes received and simplifies how flush_to_ldisc counts the remaining bytes. It also fixes a bug of lost bytes on n_tty when flushing too many bytes via the USB serial gadget driver.

Input: i8042 - downgrade selftest error message to dbg()

2011-03-31T07:12:40Z

On a "really fragile" laptop I noticed a single i8042.c: i8042 controller selftest failed. (0x1 != 0x55) error in the log. But there's no reason to print this message at KERN_ERR level each time that loop fails, especially since the message telling about the overall selftest failure is printed at KERN_INFO level (on X86). Add an actual error message for non-X86 systems, where a selftest failure is (apparently) more serious. Remove a space in an another error message.
