FUJITA Tomonori 14e507b852 sg: restore command permission for TYPE_SCANNER
sg allowed any command for TYPE_SCANNER. The cmd_filter patchset
doesn't. We can't change sg's permission since it might break the
existing software.

FUJITA Tomonori abf5439370 block: move cmdfilter from gendisk to request_queue
cmd_filter works only for the block layer SG_IO with SCSI block
devices. It breaks scsi/sg.c, bsg, and the block layer SG_IO with SCSI
character devices (such as st). We hit a kernel crash with them.

The problem is that cmd_filter code accesses to gendisk (having struct
blk_scsi_cmd_filter) via inode->i_bdev->bd_disk. It works for only
SCSI block device files. With character device files, inode->i_bdev
leads you to struct cdev. inode->i_bdev->bd_disk->blk_scsi_cmd_filter
isn't safe.

SCSI ULDs don't expose gendisk; they keep it private. bsg needs to be
independent on any protocols. We shouldn't change ULDs to expose their
gendisk.

This patch moves struct blk_scsi_cmd_filter from gendisk to
request_queue, a common object, which eveyone can access to.

The user interface doesn't change; users can change the filters via
/sys/block/. gendisk has a pointer to request_queue so the cmd_filter
code accesses to struct blk_scsi_cmd_filter.

Masakazu Mokuno b47027795a powerpc/ps3: Fix ioremap of spu shadow regs
Fix the ioremap of the spu shadow regs on the PS3.

The current PS3 hypervisor requires the spu shadow regs to be
mapped with the PTE page protection bits set as read-only (PP=3).
This implementation uses the low level __ioremap() to bypass the
page protection settings inforced by ioremap_flags() to get the
needed PTE bits set for the shadow regs.

This fixes a runtime failure on the PS3 introduced by the powerpc
ioremap_prot rework of commit a1f242ff46
("powerpc ioremap_prot").

Linus Torvalds d25e26b61d [x86] Clean up MAXSMP Kconfig, and limit NR_CPUS to 512
This fixes a regression that was indirectly caused by commit
1184dc2ffe ("x86: modify Kconfig to allow
up to 4096 cpus").

Allowing 4k CPU's is not practical at this time, because we still have a
number of places that have several 'cpumask_t's on the stack, and a
4k-bit cpumask is 512 bytes of stack-space for each such variable.  This
literally caused functions like 'smp_call_function_mask' to have a 2.5kB
stack frame, and several functions to have 2kB stackframes.

With an 8kB stack total, smashing the stack was simply much too likely.
At least bugzilla entry

	http://bugzilla.kernel.org/show_bug.cgi?id=11342

was due to this.

The earlier commit to not inline load_module() into sys_init_module()
fixed the particular symptoms of this that Alan Brunelle saw in that
bugzilla entry, but the huge stack waste by cpumask_t's was the more
direct cause.

Some day we'll have allocation helpers that allocate large CPU masks
dynamically, but in the meantime we simply cannot allow cpumasks this
large.

James Bottomley 8a549f8b58 [IA64] Fix __{in,out}s{w,l} to handle unaligned data
Some ia64 systems produce several repeats of kernel messages like this:

 kernel unaligned access to 0xe000000644220466, ip=0xa000000100516fa1

This was tracked to ide code using the __cmd[] field in "struct request"
via the __outsw() function.  __cmd[] is a char array, so is not guaranteed
to be properly aligned when accessed as words.
