[PATCH] cleanup asm/setup.h userspace visibility

2006-12-07T16:39:46+00:00

Make the contents of the userspace asm/setup.h header consistent on all
architectures:

 - export setup.h to userspace on all architectures
 - export only COMMAND_LINE_SIZE to userspace
 - frv: move COMMAND_LINE_SIZE from param.h
 - i386: remove duplicate COMMAND_LINE_SIZE from param.h
 - arm:
   - export ATAGs to userspace
   - change u8/u16/u32 to __u8/__u16/__u32

[PATCH] Directed yield: direct yield of spinlocks for s390.

2006-10-01T07:39:22+00:00

Use the new diagnose 0x9c in the spinlock implementation for s390.  It
yields the remaining timeslice of the virtual cpu that tries to acquire a
lock to the virtual cpu that is the current holder of the lock.

[S390] ipl/dump on panic.

2006-09-20T13:58:49+00:00

It is now possible to specify a ccw/fcp dump device which is used to
automatically create a system dump in case of a kernel panic. The dump
device can be configured under /sys/firmware/dump.
In addition it is now possible to specify a ccw/fcp device which is used
for the next reboot of Linux. The reipl device can be configured under
/sys/firmware/reipl.

[S390] initrd vs. bootmem bitmap.

2006-09-20T13:58:41+00:00

Move initrd if the bitmap of the bootmem allocator would overwrite it.
In addition this patch sets the default size and address of the initrd to 0.
Therefore all boot loaders must set the initrd size and address correctly.
This is especially relevant for ftp boot via HMC/SE, where this change
requires a special patch file entry in the .ins file which sets these two
values contained at address 0x10408 and 0x10410.

[PATCH] s390: export ipl device parameters

2005-10-31T01:37:16+00:00

Sysfs interface to export ipl device parameters.  Dependent on the ipl type
the interface will look like this:

- ccw ipl:

/sys/firmware/ipl/device
		 /ipl_type

- fcp ipl:

/sys/firmware/ipl/binary_parameter
		 /bootprog
		 /br_lba
		 /device
		 /ipl_type
		 /lun
		 /scp_data
		 /wwpn

- otherwise (unknown that is):

/sys/firmware/ipl/ipl_type
