The memset() of the sg entry was originally removed, because it could
overwrite a chain pointer. But it's quite OK to memset() it when we know
it's a valid entry, since it can't contain a chain pointer.Signed-off-by: Jens Axboe

This patch disables DMA refetch in the PCI bridge. We have disabled DMA
prefetch for quite some time. Testing with XEN revealed another ASIC bug. If
dom0 resides on a P600 the board can can an MCA bi accessing invalid memory
addresses. Apparently, we need to disable both prefetch and refetch.
My understanding is a refetch operation should not occur but it is a valid
thing to do if prefetched data is no longer available for whatever reason.
Please consider this patch for inclusion.Signed-off-by: Mike Miller

This fixes the new EMAC driver for the NAPI updates. The previous patch

Apparently poking the link status registers when autonegotiation
is running on the PHY might botch the PHY link on 80003es2lan
devices. While this is a very rare condition we can completely
avoid it alltogether by just using the MAC link bits to provide
the proper information to ethtool.Signed-off-by: Auke Kok

main change:
* greatly improve per-NIC probe diagnostic output. Similar to other
net drivers, print out MAC address, PHY info, and various hardware and
software flags that may be relevant.other changes:
* similar to other net drivers, only print the initial version message
when we have found at least one board.* don't bother to print error message when pci_enable_device() fails,
it will do so for us.* use dev_printk() rather than printk() in nv_probe(). This gives
use a standardized output similar to the rest of the kernel, and
eliminates the need to manually print out PCI bus id.* use DRV_NAME constant where appropriate
* clean struct pci_driver indentation

This patch kills ugly warnings when the "Improve SELinux performance

Signed-off-by: James Morris -
* We add ebitmap_for_each_positive_bit() which enables to walk on
any positive bit on the given ebitmap, to improve its performance
using common bit-operations defined in linux/bitops.h.
In the previous version, this logic was implemented using a combination
of ebitmap_for_each_bit() and ebitmap_node_get_bit(), but is was worse
in performance aspect.
This logic is most frequestly used to compute a new AVC entry,
so this patch can improve SELinux performance when AVC misses are happen.
* struct ebitmap_node is redefined as an array of "unsigned long", to get
suitable for using find_next_bit() which is fasted than iteration of
shift and logical operation, and to maximize memory usage allocated
from general purpose slab.
* Any ebitmap_for_each_bit() are repleced by the new implementation
in ss/service.c and ss/mls.c. Some of related implementation are
changed, however, there is no incompatibility with the previous
version.
* The width of any new line are less or equal than 80-chars.The following benchmark shows the effect of this patch, when we
access many files which have different security context one after
another. The number is more than /selinux/avc/cache_threshold, so
any access always causes AVC misses.selinux-2.6 selinux-2.6-ebitmap

Allow policy to select, in much the same way as it selects MLS support, how
the kernel should handle access decisions which contain either unknown
classes or unknown permissions in known classes. The three choices for the
policy flags are0 - Deny unknown security access. (default)
2 - reject loading policy if it does not contain all definitions
4 - allow unknown security accessThe policy's choice is exported through 2 booleans in
selinuxfs. /selinux/deny_unknown and /selinux/reject_unknown.Signed-off-by: Eric Paris

It reduces the selinux overhead on read/write by only revalidating
permissions in selinux_file_permission if the task or inode labels have
changed or the policy has changed since the open-time check. A new LSM
hook, security_dentry_open, is added to capture the necessary state at open
time to allow this optimization.(see http://marc.info/?l=selinux&m=118972995207740&w=2)

This patch reduces memory usage of SELinux by tuning avtab. Number of hash
slots in avtab was 32768. Unused slots used memory when number of rules is
fewer. This patch decides number of hash slots dynamically based on number
of rules. (chain length)^2 is also printed out in avtab_hash_eval to see
standard deviation of avtab hash table.Signed-off-by: Yuichi Nakamura
