[PATCH v2] serial_core: fix uart PORT_UNKNOWN handling

From: "Thomas Pfaff" While porting a RS485 driver from 2.6.29 to 3.14, i noticed that the serial tty driver could break it by using uart ports that it does not own : 1. uart_change_pm ist called during uart_open and calls the uart pm function without checking for PORT_UNKNOWN.

2.4.2: System clock slows down under load

Hi all, i decided to make a test for the 2.4 kernel on my old hardware (Gigabyte EISA/VLB with an AMD 486 DX4 133). The kernel boots fine but there is one strange thing: The system clock slows down under load, after a make dep in the linux src directory it is about 2 minutes behind. This appears
