[S390] IRQs too early enabled.

2006-11-06T09:49:02Z

setup_lowcore() calls ctl_set_bit() which returns withs interrupts enabled. The setup arch code is not supposed to enable interrupts that early. Therefore use the __ctl_set_bit() variant. This fixes the not working lock dependency validator on non 64 bit systems. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] revert add_active_range() usage patch.

2006-11-06T09:49:00Z

Commit 7676bef9c183fd573822cac9992927ef596d584c breaks DCSS support on s390. DCSS needs initialized struct pages to work. With the usage of add_active_range() only the struct pages for physically present pages are initialized. This could be fixed if the DCSS driver would initiliaze the struct pages itself, but this doesn't work too. This is because the mem_map array does not include holes after the last present memory area and therefore there is nothing that could be initialized. To fix this and to avoid some dirty hacks revert this patch for now. Will be added later when we move to a virtual mem_map.

[S390] Inline assembly cleanup.

2006-09-28T14:56:43Z

Major cleanup of all s390 inline assemblies. They now have a common coding style. Quite a few have been shortened, mainly by using register asm variables. Use of the EX_TABLE macro helps as well. The atomic ops, bit ops and locking inlines new use the Q-constraint if a newer gcc is used. That results in slightly better code. Thanks to Christian Borntraeger for proof reading the changes.

[S390] Use alternative user-copy operations for new hardware.

[S390] Make user-copy operations run-time configurable.

[S390] ipl/dump on panic.

2006-09-20T13:58:49Z

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.

2006-09-20T13:58:41Z

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.
