2008-03-06sh: Fix up SH7710 VoIP-GW build.Paul Mundt
The only board-specific bits that existed here were for setting up the IRQs, which are now handled by the SH7710 CPU support code instead. As there's nothing else to do for setup, kill off the board support code and have the defconfig use the generic machvec instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2008-03-06[XFS] fix inode leak in xfs_iget_core()David Chinner
If the radix_tree_preload() fails, we need to destroy the inode we just read in before trying again. This could leak xfs_vnode structures when there is memory pressure. Noticed by Christoph Hellwig.

wakeups Idle state is not being detected properly by the xfsaild push code. The current idle state is detected by an empty list which may never happen with mostly idle filesystem or one using lazy superblock counters. A single dirty item in the list that exists beyond the push target can result repeated looping attempting to push up to the target because it fails to check if the push target has been acheived or not. Fix by considering a dirty list with everything past the target as an idle state and set the timeout appropriately.

2008-03-06fb: pvr2fb: Fix up remaining section mismatch.Paul Mundt
Building with CONFIG_DEBUG_SECTION_MISMATCH=y reports: CC drivers/video/pvr2fb.o LD drivers/video/built-in.o WARNING: drivers/video/built-in.o(.text+0xb9b0): Section mismatch in reference from the function pvr2fb_check_var() to the variable .devinit.data:pvr2_fix The function pvr2fb_check_var() references the variable __devinitdata pvr2_fix. This is often because pvr2fb_check_var lacks a __devinitdata annotation or the annotation of pvr2_fix is wrong. This is obviously crap as no such reference exists, but it's a bit closer to reality from older versions which blamed the PCI table. The real problem was a reference to pvr2_var.vmode from pvr2fb_check_var(), as pvr2_var is flagged as __devinitdata (pvr2_fix is also, so at least that part is right). pvr2_var.vmode is just a fancy way of saying FB_VMODE_NONINTERLACED, so we just reference that explicitly instead.

2008-03-06NFS: use new LSM interfaces to explicitly set mount optionsEric Paris
NFS and SELinux worked together previously because SELinux had NFS specific knowledge built in. This design was approved by both groups back in 2004 but the recent NFS changes to use nfs_parsed_mount_data and the usage of nfs_clone_mount_data showed this to be a poor fragile solution. This patch fixes the NFS functionality regression by making use of the new LSM interfaces to allow an FS to explicitly set its own mount options. The explicit setting of mount options is done in the nfs get_sb functions which are called before the generic vfs hooks try to set mount options for filesystems which use text mount data. This does not currently support NFSv4 as that functionality did not exist in previous kernels and thus there is no regression. I will be adding the needed code, which I believe to be the exact same as the v3 code, in nfs4_get_sb for 2.6.26.

2008-03-06LSM/SELinux: Interfaces to allow FS to control mount optionsEric Paris
Introduce new LSM interfaces to allow an FS to deal with their own mount options. This includes a new string parsing function exported from the LSM that an FS can use to get a security data blob and a new security data blob. This is particularly useful for an FS which uses binary mount data, like NFS, which does not pass strings into the vfs to be handled by the loaded LSM. Also fix a BUG() in both SELinux and SMACK when dealing with binary mount data. If the binary mount data is less than one page the copy_page() in security_sb_copy_data() can cause an illegal page fault and boom. Remove all NFSisms from the SELinux code since they were broken by past NFS changes.

Since in addition the z/VM memory increment size is 1MB force MAX_ORDER to be 9, so we can support 1MB segments.
