Subject: [PATCH] acpi: do not skip BIOS scan if EBDA length is zero
|
||||
|
||||
EBDA layout is not standardized so we cannot assume first two bytes
|
||||
are length. Neither is it required by ACPI standard. HP 8710W is known
|
||||
to contain zeroes here.
|
||||
|
||||
Closes: 45002

Subject: [PATCH] i386: fix TSC calibration using PIT
|
||||
|
||||
Condition was accidentally reversed, so PIT calibration always failed
|
||||
when PIT was present and always succeeded when PIT was missing, but in
|
||||
the latter case resulted in absurdly fast clock.
|
||||
|
||||
