# # LAPB Data Link Drive # config LAPB tristate "LAPB Data Link Driver" ---help--- Link Access Procedure, Balanced (LAPB) is the data link layer (i.e. the lower) part of the X.25 protocol. It offers a reliable connection service to exchange data frames with one other host, and it is used to transport higher level protocols (mostly X.25 Packet Layer, the higher part of X.25, but others are possible as well). Usually, LAPB is used with specialized X.21 network cards, but Linux currently supports LAPB only over Ethernet connections. If you want to use LAPB connections over Ethernet, say Y here and to "LAPB over Ethernet driver" below. Read for technical details. To compile this driver as a module, choose M here: the module will be called lapb. If unsure, say N. it.cgi/linux/net-next.git/'>net-next.git

parisc: Don't use BITS_PER_LONG in userspace-exported swab.h header
In swab.h the "#if BITS_PER_LONG > 32" breaks compiling userspace programs if BITS_PER_LONG is #defined by userspace with the sizeof() compiler builtin. Solve this problem by using __BITS_PER_LONG instead. Since we now #include asm/bitsperlong.h avoid further potential userspace pollution by moving the #define of SHIFT_PER_LONG to bitops.h which is not exported to userspace. This patch unbreaks compiling qemu on hppa/parisc. Signed-off-by: Helge Deller <deller@gmx.de> Cc: <stable@vger.kernel.org>
