Clean up linux emulation code to make it architecture-independent as much as possible. * linux: Renamed from linuxdev. * Makefile.in (objfiles): Add linux.o instead of linuxdev.o. (MAKE): New variable. Used for the linux.o target. * configure.in: Add AC_CHECK_TOOL(MAKE, make). * i386/i386/spl.h: Include <i386/ipl.h>, for compatibility with OSF Mach 3.0. Suggested by Elgin Lee <ehl@funghi.com>. * linux/src: Renamed from linux/linux. * linux/dev: Renamed from linux/mach. * linux/Drivers.in (AC_INIT): Use dev/include/linux/autoconf.h, instead of mach/include/linux/autoconf.h. * Makefile.in (all): Target ../linux.o instead of ../linuxdev.o. * linux/dev/drivers/block/genhd.c: Include <machine/spl.h> instead of <i386/ipl.h>. * linux/dev/drivers/net/auto_irq.c: Remove unneeded header files, <i386/ipl.h> and <i386/pic.h>. * linux/dev/init/main.c: Many i386-dependent codes moved to ... * linux/dev/arch/i386/irq.c: ... here. * linux/dev/arch/i386/setup.c: New file. * linux/dev/arch/i386/linux_emul.h: Likewise. * linux/dev/arch/i386/glue/timer.c: Merged into sched.c. * linux/dev/arch/i386/glue/sched.c: Include <machine/spl.h> instead of <i386/ipl.h>, and moved to ... * linux/dev/kernel/sched.c: ... here. * linux/dev/arch/i386/glue/block.c: Include <machine/spl.h> and <linux_emul.h>, instead of i386-dependent header files, and moved to ... * linux/dev/glue/blocl.c: ... here. * linux/dev/arch/i386/glue/net.c: Include <machine/spl.h> and <linux_emul.h>, instead of i386-dependent header files, and moved to ... * linux/dev/glue/net.c: ... here. * linux/dev/arch/i386/glue/misc.c: Remove `x86' and moved to ... * linux/dev/glue/misc.c: ... here. * linux/dev/arch/i386/glue/kmem.c: Moved to ... * linux/dev/glue/kmem.c: ... here.

+/************************** DOCUMENTATION **************************/
+/*
+ * This driver provide a Linux interface to the Wavelan ISA hardware
+ * The Wavelan is a product of Lucent ("http://wavelan.netland.nl/").
+ * This division was formerly part of NCR and then AT&T.
+ * Wavelan are also distributed by DEC (RoamAbout), Digital Ocean and
+ * Aironet (Arlan). If you have one of those product, you will need to
+ * make some changes below...
+ *
+ * This driver is still a beta software. A lot of bugs have been corrected,
+ * a lot of functionalities are implemented, the whole appear pretty stable,
+ * but there is still some area of improvement (encryption, performance...).
+ *
+ * To know how to use this driver, read the NET3 HOWTO.
+ * If you want to exploit the many other fonctionalities, look comments
+ * in the code...
+ *
+ * This driver is the result of the effort of many peoples (see below).
+ */
+
+/* ------------------------ SPECIFIC NOTES ------------------------ */
+/*
+ * wavelan.o is darn too big
+ * -------------------------
+ * That's true ! There is a very simple way to reduce the driver
+ * object by 33% (yes !). Comment out the following line :
+ * #include <linux/wireless.h>
+ *
+ * MAC address and hardware detection :
+ * ----------------------------------
+ * The detection code of the wavelan chech that the first 3
+ * octets of the MAC address fit the company code. This type of
+ * detection work well for AT&T cards (because the AT&T code is
+ * hardcoded in wavelan.h), but of course will fail for other
+ * manufacturer.
+ *
+ * If you are sure that your card is derived from the wavelan,
+ * here is the way to configure it :
+ * 1) Get your MAC address
+ * a) With your card utilities (wfreqsel, instconf, ...)
+ * b) With the driver :
+ * o compile the kernel with DEBUG_CONFIG_INFO enabled
+ * o Boot and look the card messages
+ * 2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan.h)
+ * 3) Compile & verify
+ * 4) Send me the MAC code - I will include it in the next version...
+ *
+ * "CU Inactive" message at boot up :
+ * -----------------------------------
+ * It seem that there is some weird timings problems with the
+ * Intel microcontroler. In fact, this message is triggered by a
+ * bad reading of the on board ram the first time we read the
+ * control block. If you ignore this message, all is ok (but in
+ * fact, currently, it reset the wavelan hardware).
+ *
+ * To get rid of that problem, there is two solution. The first
+ * is to add a dummy read of the scb at the end of
+ * wv_82586_config. The second is to add the timers
+ * wv_synchronous_cmd and wv_ack (the udelay just after the
+ * waiting loops - seem that the controler is not totally ready
+ * when it say it is !).
+ *
+ * In the current code, I use the second solution (to be
+ * consistent with the original solution of Bruce Janson).
+ */
+
+/* --------------------- WIRELESS EXTENSIONS --------------------- */
+/*
+ * This driver is the first one to support "wireless extensions".
+ * This set of extensions provide you some way to control the wireless
+ * caracteristics of the hardware in a standard way and support for
+ * applications for taking advantage of it (like Mobile IP).
+ *
+ * You will need to enable the CONFIG_NET_RADIO define in the kernel
+ * configuration to enable the wireless extensions (this is the one
+ * giving access to the radio network device choice).
+ *
+ * It might also be a good idea as well to fetch the wireless tools to
+ * configure the device and play a bit.

+
+/* --------------------------- HISTORY --------------------------- */
+/*
+ * (Made with information in drivers headers. It may not be accurate,
+ * and I garantee nothing except my best effort...)
+ *
+ * The history of the Wavelan drivers is as complicated as history of
+ * the Wavelan itself (NCR -> AT&T -> Lucent).
+ *
+ * All started with Anders Klemets <klemets@paul.rutgers.edu>,
+ * writting a Wavelan ISA driver for the MACH microkernel. Girish
+ * Welling <welling@paul.rutgers.edu> had also worked on it.
+ * Keith Moore modify this for the Pcmcia hardware.
+ *
+ * Robert Morris <rtm@das.harvard.edu> port these two drivers to BSDI
+ * and add specific Pcmcia support (there is currently no equivalent
+ * of the PCMCIA package under BSD...).
+ *
+ * Jim Binkley <jrb@cs.pdx.edu> port both BSDI drivers to freeBSD.
+ *
+ * Bruce Janson <bruce@cs.usyd.edu.au> port the BSDI ISA driver to Linux.
+ *
+ * Anthony D. Joseph <adj@lcs.mit.edu> started modify Bruce driver
+ * (with help of the BSDI PCMCIA driver) for PCMCIA.
+ * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished is work.
+ * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
+ * correctly 2.00 cards (2.4 GHz with frequency selection).
+ * David Hinds <dhinds@hyper.stanford.edu> integrated the whole in his
+ * Pcmcia package (+ bug corrections).
+ *
+ * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
+ * patchs to the Pcmcia driver. After, I added code in the ISA driver
+ * for Wireless Extensions and full support of frequency selection
+ * cards. Then, I've done the same to the Pcmcia driver + some
+ * reorganisation. Finally, I came back to the ISA driver to
+ * upgrade it at the same level as the Pcmcia one and reorganise
+ * the code
+ * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
+ * much needed informations on the Wavelan hardware.
