[PATCH] security issue in firmware system
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. ]

[PATCH] kswapd lockup fix
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;
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 :(

This one removes the other occurences of "°C"; fixes displayed fan speed so
that it uses the same scale than other occurences of this parameter instead
of RPM only; fixes the RPM reading of the fan so that it shows zero instead
of 82 when it is effectively stopped.

hugetblfs appears not to support the creation of files larger than 2GB.
hugetlbfs_vmtruncate() checks against the s_maxbytes member of the super
block and returns EFBIG if the requested file size is too large.

Fix warnings in kernel/power/console.c by only declaring orig_fgconsole
and orig_kmsg when required by SUSPEND_CONSOLE. Restore kmsg_redirect on
resume.

[PATCH] i2o.h fix
i2o.h uses stuff defined in linux/dma-mapping.h but includes
asm/dma-mapping.h instead. It works by accident on some platforms
(they end up pulling linux/dma-mapping.h from asm-generic/pci-dma-compat.h
before it hits the fan), but breaks on e.g. alpha.
