* 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_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 ...

/*
* With the qlogic interface, every queue slot can hold a SCSI
* command with up to 4 scatter/gather entries. If we need more
* than 4 entries, continuation entries can be used that hold
* another 7 entries each. Unlike for other drivers, this means
* that the maximum number of scatter/gather entries we can
* support at any given time is a function of the number of queue
* slots available. That is, host->can_queue and host->sg_tablesize
* are dynamic and _not_ independent. This all works fine because
* requests are queued serially and the scatter/gather limit is
* determined for each queue request anew.
