The patch titled
Subject: x86: net5501: platform driver for Soekris Engineering net5501 single-board computer
has been removed from the -mm tree. Its filename was
net5501-platform-driver-for-soekris-engineering-net5501-single-board-computer.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

From: Philip Prindeville <philipp@xxxxxxxxxxxxxxxxxxxxx>
Subject: x86: net5501: platform driver for Soekris Engineering net5501 single-board computer
Platform driver for Soekris Engineering net5501 single-board computer.
Probes well-known locations in ROM for BIOS signature to confirm correct
platform. Registers 1 LED and 1 GPIO-based button (typically used for
soft reset).
[akpm@xxxxxxxxxxxxxxxxxxxx: remove Kconfig and Makefile detritus from drivers/leds/]
