Currently selinux_sb_copy_data requires an entire page be allocated to
*orig when the function is called. This "requirement" is based on the fact
that we call copy_page(in_save, nosec_save) and in_save = orig when the
data is not FS_BINARY_MOUNTDATA. This means that if a caller were to call
do_kern_mount with only about 10 bytes of options, they would get passed
here and then we would corrupt PAGE_SIZE - 10 bytes of memory (with all
zeros.)
Currently it appears all in kernel FS's use one page of data so this has
not been a problem. An out of kernel FS did just what is described above
and it would almost always panic shortly after they tried to mount. From
looking else where in the kernel it is obvious that this string of data
must always be null terminated. (See example in do_mount where it always
zeros the last byte.) Thus I suggest we use strcpy in place of copy_page.
In this way we make sure the amount we copy is always less than or equal to
the amount we received and since do_mount is zeroing the last byte this
should be safe for all.

Remove legacy ISA serial ports for Accent, Boca, Fourport, Hub6 and MCA
from the architecture specific serial.h include.
The only ports which remain in asm-*/serial.h are the platform specific

I am using the atxp1 module to change vcore on my NForce2 via userspace
daemon (see punnoor.de).
Currently the atxp1 module will write to the log on every vcore change,
thus filling up my log - which I don't want. I am no kernel coder, but
I guess, this one-liner will change this behaviour in a wanted way, ie
output will be made for debug purposes only.

Anyone reporting a stuck IRQ should try these options. Its effectiveness
varies we've found in the Fedora case. Quite a few systems with misdescribed
IRQ routing just work when you use irqpoll. It also fixes up the VIA systems
although thats now fixed with the VIA quirk (which we could just make default
as its what Redmond OS does but Linus didn't like it historically).
A small number of systems have jammed IRQ sources or misdescribes that cause
an IRQ that we have no handler registered anywhere for. In those cases it
doesn't help.

Currently in ext3 block reservation code, the global filesystem reservation
tree lock (rsv_block) is hold during the process of searching for a space
to make a new reservation window, including while scaning the block bitmap
to verify if the avalible window has a free block. Holding the lock during
bitmap scan is unnecessary and could possibly cause scalability issue and
latency issues.
This patch tries to address this by dropping the lock before scan the
bitmap. Before that we need to reserve the open window in case someone
else is targetting at the same window. Question was should we reserve the
whole free reservable space or just the window size we need. Reserve the
whole free reservable space will possibly force other threads which
intended to do block allocation nearby move to another block group(cause
bad layout). In this patch, we just reserve the desired size before drop
the lock and scan the block bitmap. This patch fixed a ext3 reservation
latency issue seen on a cvs check out test. Patch is tested with many fsx,
tiobench, dbench and untar a kernel test.

get_io_context needlessly turned off interrupts and checked for racing io
context creations. Both of which aren't needed, because the io context can
only be created while in process context of the current process.
Also, split the function in 2. A light version, current_io_context does not
elevate the reference count specifically, but can be used when in process
context, because the process holds a reference itself.
