[PATCH 5/5] U6715 16550A serial driver support
UART Features extract from STEricsson U6715 data-sheet (arm926 SoC for mobile phone): * Fully compatible with industry standard 16C550 and 16C450 from various manufacturers * RX and TX 64 byte FIFO reduces CPU interrupts * Full double buffering * Modem control signals include CTS, RTS, (and DSR, DTR on UART1 only)... 5 Aug 2010 09:07

[PATCH] timekeeping: Fix overflow in rawtime tv_nsec on 32 bit archs
The tv_nsec is a long and when added to the shift value it can wrap and become negative which later causes looping problems in the getrawmonotonic(). The edge case occurs when the system has slept for a short period of time of ~2 seconds. A trace printk of the values in this patch illustrate the problem: ftra... 5 Aug 2010 09:07
