ieee1394: prevent device binding of raw1394, video1394, dv1394
These drivers don't need to match any unit_directory type device.
They just need the id_table for module autoloading per module alias.
Not binding any of these drivers allows special-purpose drivers with
similar or same IDs to bind to devices. This currently only benefits
out-of-tree drivers; on the other hand it is in no way detrimental to
in-tree drivers.

x86-64: introduce struct pci_sysdata to facilitate sharing of ->sysdata
This patch introduces struct pci_sysdata to x86 and x86-64, and
converts the existing two users (NUMA, Calgary) to use it.
This lays the groundwork for having other users of sysdata, such as
the PCI domains work.
The Calgary bits are tested, the NUMA bits just look ok.
replaces pcibios_scan_root by pci_scan_bus_parented...
but in pcibios_scan_root we have a check about scanned busses.

mm: sparsemem memory_present() fix
Fix memory corruption and crash on 32-bit x86 systems.
If a !PAE x86 kernel is booted on a 32-bit system with more than 4GB of
RAM, then we call memory_present() with a start/end that goes outside
the scope of MAX_PHYSMEM_BITS.
That causes this loop to happily walk over the limit of the sparse
memory section map:
for (pfn = start; pfn < end; pfn += PAGES_PER_SECTION) {
unsigned long section = pfn_to_section_nr(pfn);
struct mem_section *ms;
sparse_index_init(section, nid);
set_section_nid(section, nid);
ms = __nr_to_section(section);
if (!ms->section_mem_map)
ms->section_mem_map = sparse_encode_early_nid(nid) |
SECTION_MARKED_PRESENT;
'ms' will be out of bounds and we'll corrupt a small amount of memory by
encoding the node ID and writing SECTION_MARKED_PRESENT (==0x1) over it.
The corruption might happen when encoding a non-zero node ID, or due to
the SECTION_MARKED_PRESENT which is 0x1:
mmzone.h:#define SECTION_MARKED_PRESENT (1UL<<0)
The fix is to sanity check anything the architecture passes to
sparsemem.
This bug seems to be rather old (as old as sparsemem support itself),
but the exact incarnation depended on random details like configs, which
made this bug more prominent in v2.6.25-to-be.
An additional enhancement might be to print a warning about ignored or
trimmed memory ranges.

netconsole: only set CON_PRINTBUFFER if the user specifies a netconsole
Since
0bcc1816188e570bde1d56a208996660f2633ae0 (netconsole: Support
dynamic reconfiguration using configfs), the netconsole is always
registered, regardless of whether the user actually specified a
netconsole configuration on the command line.
However because netconsole has CON_PRINTBUFFER set, when it is
registered it causes the printk buffer to be replayed to all consoles.
When there is no netconsole configured this is a) pointless, and b)
somewhat annoying for the user of the existing console.
So instead we should only set CON_PRINTBUFFER if there is a netconsole
configuration found on the command line. This retains the existing
behaviour if a netconsole is setup by the user, and avoids spamming
other consoles when we're only registering for the dynamic
netconsole case.

JFFS2 Fix of panics caused by wrong condition for hole frag creation in write_begin
This fixes a regression introduced in commit
205c109a7a96d9a3d8ffe64c4068b70811fef5e8 when switching to
write_begin/write_end operations in JFFS2.
The page offset is miscalculated, leading to corruption of the fragment
lists and subsequently to memory corruption and panics.
[ Side note: the bug is a fairly direct result of the naming. Nick was
likely misled by the use of "offs", since we tend to use the notion of
"offset" not as an absolute position, but as an offset _within_ a page
or allocation.
Alternatively, a "pgoff_t" is a page index, but not a byte offset -
our VM naming can be a bit confusing.
So in this case, a VM person would likely have called this a "pos",
not an "offs", or perhaps talked about byte offsets rather than page
offsets (since it's counted in bytes, not pages). - Linus ]

locks: fix possible infinite loop in fcntl(F_SETLKW) over nfs
Miklos Szeredi found the bug:
"Basically what happens is that on the server nlm_fopen() calls
nfsd_open() which returns -EACCES, to which nlm_fopen() returns
NLM_LCK_DENIED.
"On the client this will turn into a -EAGAIN (nlm_stat_to_errno()),
which in will cause fcntl_setlk() to retry forever."
So, for example, opening a file on an nfs filesystem, changing
permissions to forbid further access, then trying to lock the file,
could result in an infinite loop.
And Trond Myklebust identified the culprit, from Marc Eshel and I:
7723ec9777d9832849b76475b1a21a2872a40d20 "locks: factor out
generic/filesystem switch from setlock code"
That commit claimed to just be reshuffling code, but actually introduced
a behavioral change by calling the lock method repeatedly as long as it
returned -EAGAIN.
We assumed this would be safe, since we assumed a lock of type SETLKW
would only return with either success or an error other than -EAGAIN.
However, nfs does can in fact return -EAGAIN in this situation, and
independently of whether that behavior is correct or not, we don't
actually need this change, and it seems far safer not to depend on such
assumptions about the filesystem's ->lock method.
Therefore, revert the problematic part of the original commit. This
leaves vfs_lock_file() and its other callers unchanged, while returning
fcntl_setlk and fcntl_setlk64 to their former behavior.

[DCCP]: Fix skb->cb conflicts with IP
dev_queue_xmit() and the other IP output functions expect to get a skb
with clear or properly initialized skb->cb. Unlike TCP and UDP, the
dccp_skb_cb doesn't contain a struct inet_skb_parm at the beginning,
so the DCCP-specific data is interpreted by the IP output functions.
This can cause false negatives for the conditional POST_ROUTING hook
invocation, making the packet bypass the hook.
Add a inet_skb_parm/inet6_skb_parm union to the beginning of
dccp_skb_cb to avoid clashes. Also add a BUILD_BUG_ON to make
sure it fits in the cb.
[ Combined with patch from Gerrit Renker to remove two now unnecessary
memsets of IPCB(skb)->opt ]

[AX25]: Potential ax25_uid_assoc-s leaks on module unload.
The ax25_uid_free call walks the ax25_uid_list and releases entries
from it. The problem is that after the fisrt call to hlist_del_init
the hlist_for_each_entry (which hides behind the ax25_uid_for_each)
will consider the current position to be the last and will return.
Thus, the whole list will be left not freed.

tg3: fix MMIO for PPC 44x platforms
The driver stores the PCI resource addresses into 'unsigned long' variable
before calling ioremap_nocache() on them. This warrants kernel oops when the
registers are accessed on PPC 44x platforms which (being 32-bit) have PCI
memory space mapped beyond 4 GB.
The arch/ppc/ kernel has a fixup in ioremap() that creates an illusion that
the PCI memory resource is mapped below 4 GB, but arch/powerpc/ code got rid
of this trick, having instead CONFIG_RESOURCES_64BIT enabled.

Mark generic HDLC + PPP as broken.
PPP support in generic HDLC in Linux 2.6.25 is broken and will cause
a kernel panic when a device configured in PPP mode is activated.
It will be replaced by new PPP implementation after Linux 2.6.25 is
released.
This affects only PPP support in generic HDLC (mostly Hitachi SCA
and SCA-II based drivers, wanxl, and few others). Standalone syncppp
and async PPP support are not affected.

forcedeth: mac address fix
This critical patch fixes a mac address issue recently introduced. If the
device's mac address was in correct order and the flag
NVREG_TRANSMITPOLL_MAC_ADDR_REV was set, during nv_remove the flag would get
cleared. During next load, the mac address would get reversed because the
flag is missing.
As it has been indicated previously, the flag is cleared across a low power
transition. Therefore, the driver should set the mac address back into the
reversed order when clearing the flag.
Also, the driver should set back the flag after a low power transition to
protect against kexec command calling nv_probe a second time.
