None of the compatibility defines make sense for assembly files, and gcc has trouble with vararg macros when using "-traditional" (which is used for asm), to the point of ICE'ing.

This fixes some issues with restoring the altivec and/or FPU registers upon return from a signal or when setting a context. It also add a proper stack backlink to the signal frames created for 64 bits applications.

This patch changes our open specifically for clustering software. We must allow root to access any volume or device with a LUN ID. We also modified our revalidate function for this reason. If a logical is reserved, we must register it with the OS with size=0. Then the backup system can call BLKRRPART after breaking the reservation to set the device to the correct size. We also must register a controller with no logical volumes for the online utilities to function. This is the way we've done it since the 2.2 kernel. Which doesn't neccesarily make it right, but we have legacy apps to consider. Signed off by: Mike Miller <mike.miller@hp.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

Patch from Ben Dooks This patch stops mtd from generating problems of casting pointers to ints, due to the memcpy_fromio and related functions all taking `unsigned long` for their IO addresses. Replace `unsigned long` with `void __iomem *` Compiled clean on arch-s3c2410 Signed-off-by: Ben Dooks

The firmware loader has a security issue. Firmware on some devices can write to all memory through DMA. Therefore the ability to feed firmware to the kernel is equivalent to writing to /dev/kmem. CAP_SYS_RAWIO is needed to protect itself. [ Editors note: the firmware file is 0644, and owned by root, so this "security issue" is really only an issue for people who use capabilities explicitly, rather than the regular Unix permissions. This patch makes it do the same checks we do for /dev/mem etc. ] Signed-Off-By: Oliver Neukum <oliver@neukum.name> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

This change is needed in order to allow cpus to be onlined after boot. This used to work but the declaration of pseries_secondary_smp_init in this file was changed in Ben's big cleanup patch a while back, so the cpu would start at a bad address.

Fix some bugs in the kswapd logic which can cause kswapd lockups. The balance_pgdat() logic is supposed to cause kswapd to loop across all zones in the node until each zone either a) has enough pages free or b) is deemed to be in an "all pages unreclaimable" state. In the latter case, we just give the zone a light scan on each balance_pgdat() scan and wait for the zone to come back to life again. But the zone->all_unreclaimable logic is broken - if the zone has no pages on the LRU at all, we perform no scanning of that zone (of course). So the zone->pages_scanned is not incremented and the expression if (zone->pages_scanned > zone->present_pages * 2) zone->all_unreclaimable = 1; never is satisfied. The patch changes that logic to if (zone->pages_scanned >= (zone->nr_active + zone->nr_inactive) * 4) zone->all_unreclaimable = 1; so if the zone has no LRU pages it will still enter the all_unreclaimable state. Another problem is that if the zone has no LRU pages we will tell shrink_slab() that we scanned zero LRU pages. This causes shrink_slab() to scan zero slab objects, which is obviously wrong. So change shrink_slab() to perform a decent chunk of slab scanning in this situation. And put a cond_resched() into the balance_pgdat() outer loop. Probably unnecessary, but that's what Jeff had in place when he confirmed that this patch fixed the lockup :( Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

In assembly code, there are some problems with "nosave" section (linker was doing something stupid, like duplicating the section). We attempted to fix it, but fix was worse then first problem. This fixes is for good: We no longer use any memory in the copy loop. (Plus it fixes indentation and uses meaningful labels.)

I found a couple of issues with reserve_mem: - If we try and mem_reserve something of zero length, everything reserved after it would get ignored.

Nowadays, it's possible to build CONFIG_PPC_PMAC without CONFIG_PPC_PSERIES, in which case, eeh will not be included in the build (and the eeh checks are turned into no-ops).
