On the SCSI layer ioctl path there is no implicit permissions check for
ioctls (and indeed other drivers implement unprivileged ioctls). aacraid
however allows all sorts of very admin only things to be done so should

Use the correct local variable when calling into the page allocator. Local
`flags' can have __GFP_ZERO set, which causes us to pass __GFP_ZERO into the
page allocator, possibly from illegal contexts. The page allocator will later
do prep_zero_page()->kmap_atomic(..., KM_USER0) from irq contexts and will
then go BUG.

dequeue_huge_page() has a serious memory leak upon hugetlb page
allocation. The for loop continues on allocating hugetlb pages out of
all allowable zone, where this function is supposedly only dequeue one
and only one pages.
Fixed it by breaking out of the for loop once a hugetlb page is found.

S.Caglar Onur points out that many distributions don't ship a static
zlib. Unfortunately the launcher currently maps virtual device memory
where shared libraries want to go.
The solution is to pre-scan the args to figure out how much memory we
have, then allocate devices above that, rather than down from the top
possible address. This also turns out to be simpler.

Fallout from f8a7c6fe14f556ca8eeddce258cb21392d0c3a2f. However, looking
at it shows that checks done in ASUS_LED_UNREGISTER() can't trigger
at all (we never get to asus_led_exit() if registration fails) and
if that registration fails, we actually leak stuff. IOW, it's worse
than just replacing class_dev with dev in there - the tests themselves
had been papering over the lousy cleanup logics.

The handling of the re-registration case is wrong here; the "test" that was
returned from auth_domain_lookup will not be used again, so that reference
should be put. And auth_domain_lookup never did anything with "new" in
this case, so we should just clean it up ourself.

2.6.23-rc1 turned up another batch of references from non-__init code to
__init code. In most cases, these were missing __init annotations. In one
case (os_drop_memory), the annotation was present but wrong.
init_maps is __init, but for some reason was being very careful about the
mechanism by which it allocated memory, checking whether it was OK to use
kmalloc (at this point in the boot, it definitely isn't) and using either
alloc_bootmem_low_pages or kmalloc/vmalloc. So, the kmalloc/vmalloc code is
removed.

Restructure do_aio thanks to commments from Ulrich and Al.
Uli started this by seeing that UML's initialization of a struct iocb
initialized fields that it shouldn't.
Al followed up by adding the following cleanups:
eliminating a variable by just using an anonymous structure in
its place.
hoisting a duplicated line out of the switch.
simplifying the error checking at the end.
I added a severity to the printk.

In 2.6.23-rc1, i386 fiddled its string support such that UML started getting
undefined references from modules. The UML asm/string.h was including the
i386 string.h, which defined __HAVE_ARCH_STR*, but the corresponding
implementations weren't being pulled in.
This is fixed by adding arch/i386/lib/string.h to the list of host
architecture files to be pulled in to UML.
A complication is that the libc exports file assumed that the generic strlen
and strstr weren't in use (i.e. __HAVE_ARCH_STR is defined), then they aren't
exported. This is untrue for strlen, which is exported in either case, so
this logic is not needed.

The fallocate syscall returns ENOSYS in case the filesystem does not support
the operation and expects the userlevel code to fill in. This is good in
concept.
The problem is that the libc code for old kernels should be able to
distinguish the case where the syscall is not at all available vs not
functioning for a specific mount point. As is this is not possible and we
always have to invoke the syscall even if the kernel doesn't support it.
I suggest the following patch. Using EOPNOTSUPP is IMO the right thing to do.

At present, various parts of the serial code use unsigned long to define
resource addresses. This is a problem, because some 32-bit platforms have
physical addresses larger than 32-bits, and have mmio serial uarts located
above the 4GB point.
This patch changes the type of mapbase in both struct uart_port and struct
plat_serial8250_port to resource_size_t, which can be configured to be 64
bits on such platforms. The mapbase in serial_struct can't safely be
changed, because that structure is user visible.

The interrupts of an E100 card inserted in PCI slot 4 may be on at bootup.
The resulting interrupt flood interacts with the 8259 cascade handler and
prevents proper boot up. There is a quirk for the E100 that will disable
the E100's interrupts but to use it, the 8259 cascade hookup must be
delayed until after the quirk has run. This patch delays the 8259 cascade
hookup by registering a device_initcall() which runs after the PCI quirk
for the E100.

The current 85xxCDS restart code fails to reset the PCI bus which can
lead to odd behavior after the restart. This patch uses the VIA Super
Southbridge to perform a PCI reset which will reset the entire system.
NOTE: Since the VIA chip is behind a PCI-to-PCI bridge which can be
disabled with a switch setting, it may not be possible to perform the
PCI bus reset. In this case, the code defaults to the previous restart
mechanism.

The Freescale MPC8555CDS and MPC8548CDS reference hardware has a legacy
8259 interrupt controller pair contained within a VIA VT82C686B Southbridge
on the main carrier board. The processor complex plugs into the carrier
card using a PCI slot which limits the available interrupts to the
INTA-INTD PCI interrupts. The output of the 8259 cascade pair is routed
through a gate array and connected to the PCI INTA interrupt line.
The normal interrupt chaining hook (set_irq_chained_handler) does
not allow sharing of the chained interrupt which prevents the
use of PCI INTA by PCI devices. This patch allows the 8259 cascade
pair to share their interrupt line with PCI devices.
NOTE: The addition of the .end routine for the MPIC is not strictly
necessary for this patch. It's there so this code will run from within
the threaded interrupt context used by the Real Time patch.
