[PATCH] uml: fix UML network driver endianness bugs
ifa->ifa_address and ifa->ifa_mask are defined as __u32, but used as if they
were char[4].
Network code uses htons() to convert it. So UML's method to access these
fields is wrong for bigendians (e.g. s390)
I replaced bytewise copying by memcpy(), maybe even that might be removed, if
ifa->ifa_address/mask may be used immediately.

[PATCH] uml: fix syscall stubs
Jeff Dike noted that the assembly code for syscall stubs is misassembled with
GCC 3.2.3: the values copied in registers weren't preserved between one asm()
and the following one.
So I fixed the thing by rewriting the __asm__ constraints more like unistd.h
ones.
Note: in syscall6 case I had to add one more instruction (i.e. moving arg6 in
eax and shuffling things around) - it's needed for the function to be valid in
general (we can't load the value from the stack, relative to ebp, because we
change it), but could be avoided since we actually use a constant as param 6.
The only fix would be to turn stub_syscall6 to a macro and use a "i"
constraint for arg6 (i.e., specify it's a constant value).

All the traces start at the last notifier_call_chain(...) in kernel/cpu.c.
Since we hold the cpu_control semaphore it shouldn't be any problem to access
cpu_online_map.
The reason why cpu_up failed is simply that the cpu that was supposed to be
taken online wasn't even there. That is because on s390 we never know when a
new cpu comes and therefore cpu_possible_map consists of only ones and doesn't

[PATCH] i386: LVT entries remaining unmasked on reboot
Excerpt from bugzilla entry
http://bugzilla.kernel.org/show_bug.cgi?id=5518
"i386 version of Reboot-through-BIOS is unsafe: it forgets to mask APIC LVT
interrupts before jumping to a BIOS entry point. As a result, BIOS ends up
bombarded with interrupts early on boot. The BIOS does not expect it since
following a "normal" hardware cpu reset, all APIC LVT registers have the
Mask bit (16) set and can't generate interrupts.
For example, the version of Phoenix BIOS used by VMware enables interrupts
for the first time before masking/clearing APIC LVT. The APIC Timer LVT
register is still set up for a timer interrupt delivery with a high vector
from the previous Linux incarnation (0xef in our case). The BIOS has not
fully initialized its IDT at this point and the real mode gate for 0xef
remains all zeros. Vector 0xef dispatches BIOS to address 0:0, BIOS takes
a #GP and eventually hangs.
machine_shutdown() does attempt to shut down APIC before jumping to BIOS,
but it is ineffective"

[PATCH] slab: don't BUG on duplicated cache
slab presently goes BUG if someone tries to register an already-registered

But this can happen if the user accidentally loads a module which is already
statically linked into the kernel. Nuking the kernel is rather a harsh
reaction.
Change it into a warning, and just fail the kmem_cache_alloc() attempt. If
the module is well-behaved, the modprobe will fail and all is well.

[PATCH] ppc64: Fix bug in SLB miss handler for hugepages
This patch, however, should be applied on top of the 64k-page-size patch to
fix some problems with hugepage (some pre-existing, another introduced by
this patch).
The patch fixes a bug in the SLB miss handler for hugepages on ppc64
introduced by the dynamic hugepage patch (commit id
c594adad5653491813959277fb87a2fef54c4e05) due to a misunderstanding of the
srd instruction's behaviour (mea culpa). The problem arises when a 64-bit
process maps some hugepages in the low 4GB of the address space (unusual).
In this case, as well as the 256M segment in question being marked for
hugepages, other segments at 32G intervals will be incorrectly marked for
hugepages.
In the process, this patch tweaks the semantics of the hugepage bitmaps to
be more sensible. Previously, an address below 4G was marked for hugepages
if the appropriate segment bit in the "low areas" bitmask was set *or* if
the low bit in the "high areas" bitmap was set (which would mark all
addresses below 1TB for hugepage). With this patch, any given address is
governed by a single bitmap. Addresses below 4GB are marked for hugepage
if and only if their bit is set in the "low areas" bitmap (256M
granularity). Addresses between 4GB and 1TB are marked for hugepage iff
the low bit in the "high areas" bitmap is set. Higher addresses are marked
for hugepage iff their bit in the "high areas" bitmap is set (1TB
granularity).
To avoid conflicts, this patch must be applied on top of BenH's pending
patch for 64k base page size [0]. As such, this patch also addresses a
hugepage problem introduced by that patch. That patch allows hugepages of
1MB in size on hardware which supports it, however, that won't work when
using 4k pages (4 level pagetable), because in that case hugepage PTEs are
stored at the PMD level, and each PMD entry maps 2MB. This patch simply
disallows hugepages in that case (we can do something cleverer to re-enable
them some other day).
Built, booted, and a handful of hugepage related tests passed on POWER5
LPAR (both ARCH=powerpc and ARCH=ppc64).

hardware. On current machines with 4K pages support only, the kernel
will maintain 16 "subpages" for each 64K page transparently.

Patch from Alessandro Zummo
This patch fixes AHB/PCI endianness problems when the

The patch configures the CSR register closely following the directives
in [1], paragraph 4.1, page 19.
According to the considerations in [1], page 11, while the AHB bus
supports both endian modes, on the IXP4XX it always uses big-endian.
The PCI bus is connected to the South AHB. A wrong setting in the CSR
register will thus cause a malfunctional PCI bus.
A schematic diagram of the bus interconnections on the IXP4XX
can be found in [1], page 18.
The patch has been verified to work on the NSLU2 in
both LE and BE modes.
The author is Peter Korsgaard.

[PATCH] drivers/net/wireless/airo.c unsigned comparason
fid is declared as a u32 (unsigned int), and then a few lines later, it is checked for a value < 0, which is clearly useless.
In the two locations this function is used, in one it is *explicitly* given a negative number, which would be ignored with the
current definition.

[SCSI] sd: Fix refcounting
Currently the driver takes a reference only for requests coming by way
of the gendisk, not for requests coming by way of the struct device or
struct scsi_device. Such requests can arrive in the rescan, flush,
and shutdown pathways.
The patch also makes the scsi_disk keep a reference to the underlying
scsi_device, and it erases the scsi_device's pointer to the scsi_disk
when the scsi_device is removed (since the pointer should no longer be
used).
This resolves Bugzilla entry #5237.

[MMC] Use controller id instead of driver name for printks
The printks that aren't for debugging should use the name of the controller,
not the driver name. Multiple MMC controllers aren't that common today, but
this is the right way to do things.

[PATCH] nvidiafb: Geforce 7800 series support added
This adds support for the Nvidia Geforce 7800 series of cards to the
nvidiafb framebuffer driver. All it does is add the PCI device id for
the 7800, 7800 GTX, 7800 GO, and 7800 GTX GO cards to the module device
table for the nvidiafb.ko driver, so that nvidiafb.ko will actually work
on these cards.
I also added the relevant PCI device ids to linux/pci_ids.h
I tested it on my 7800 GTX here and it works like a charm. I now can
get framebuffer support on this card! Woo hoo!! Nothing like 200x75 text
mode to make your eyes BLEED. ;)
