We recently covered a bug in mm/mmap.c on IA-64.  While unmapping a address
space, unmap_region calls free_pgtables to possibly free the pages that are
used for page tables.  Currently no distinction is made between freeing a
region that is mapped by normal pages vs the pages that are mapped by
hugepages.  Architecture specific code needs to handle cases where PTEs
corresponding to a region that is mapped by hugepages is properly getting
unmapped.  Attached please find a patch that makes the required changes in
generic part of kernel.  We will need to send a separate IA-64 patch to use
this new semantics.  Currently, so not to disturb the PPC (as that is the
only arch that had ARCH_HAS_HUGEPAGE_ONLY_RANGE defined) we are mapping back
the definition of new function hugetlb_free_pgtables to free_pgtables.

This fixes a problem similar to the patch I submitted on 11/20

http://marc.theaimsgroup.com/?l=linux-kernel&m=106936439707962&w=2

In this case, though, the result is an:

"Incorrect number of segments after building list" message.

The macro __BVEC_START assumes a bi_idx of zero when the dm code can
submit a bio with a non-zero bi_idx.
The code has been tested on an 8 way / 8gb OSDL STP machine with a 197G

I finally took the time to figure our why my parallel port wasn't
working...  here's the patch.

From: Michael Hunold <hunold@convergence.de>

the Linux-on-a-CD system Knoppix has nearly all framebuffer drivers for
2.4.23 compiled in. Additionally, it surpresses most kernel messages by
lowering the kernel log level.

Two framebuffer drivers (clgenfb.c and hgafb.c), however, use KERN_ERR
to say that their particular card has *not* been found which is very
annoying.

Especially the clgenfb.c driver simply says on bootup:
  >  Couldn't find PCI device
which can really confuse newbie users.

I've already send a patch that fixes this for 2.4 -- Marcelo and Geert
Uytterhoeven have already ack'ed it.

The same change should be done for 2.6, too IMHO.

The appended patch replaces two KERN_ERR with KERN_INFO and additionally
makes the cirrusfb.c message more descriptive.

I found linux-2.6.0-test11 leaks memory when execve fails.  I've also
checked the bitkeeper tree and the problem seems to be unchanged.

The attached patch is a partial backout of bitkeeper rev.  1.87 of
fs/exec.c.  I guess the original change was a simple mistake.

This patch fixes the "non-terminating inflate" problem that Russell King
complained about on LKML earlier today.

I chose to use "goto" much like zlib does, in order to not require
setjmp/longjmp inside the kernel.  It's a bit ugly, but it also lets each
function chose how it needs to be terminated on error, which is a good
thing.

The problem is: even if vfat_striptail_len() counts len of name without

care about len and takes whole name.  So dirs and files with dots can be
created on vfat fs.

Suppress a buffer_error() warning which occurs when a page which previously

From: David Mosberger <davidm@napali.hpl.hp.com>

This patch makes /proc/PID/maps report the range from FIXADDR_USER_START to
FIXADDR_USER_END as a final pseudo-vma.  This is consistent with the notion
that reading /proc/PID/maps tells you about every page containing data that
the process can in fact access, and with things such as ptrace allowing
access to this memory.  Without this, userland tools that want to look at all
of a process's accessible pages need special-case knowledge about things such
as the vsyscall DSO page.  With this change, existing code that iterates over
the /proc/PID/maps lines will cover those pages like any other.  For example,
this lets gdb's "gcore" command synthesize a core file from a live process
that contains the vsyscall DSO page as a real core dump would, using its
existing generic iterator code and no new special cases.

The code to parse the EBDA (Extended BIOS Data Area) for Summit boxen is
broken because it does not handle Lookout boxen (external boxes full of
additional PCI slots).  This patch cleans up some ugliness in
arch/i386/kernel/summit.c as well as fixing the code to handle Lookout boxen
and various other configurations of PCI buses.  Without this, Summit PCI bus
to node mappings are totally hosed with Lookout boxen attatched.  This patch
depends upon the GENERICARCH fix.

This patch against 2.6.0 adds a control to the SELinux module over the
inheritance of signal-related state upon security context transitions in
order to protect the new security context.  If the permission is not
granted by the policy for a given pair of contexts, then transitions
between them will clear itimers, flush all pending signals, forcibly
flush signal handlers, and unblock all signals.  Roland McGrath provided
input and feedback on the patch. 
Please apply, or let James Morris and me know if you'd like this to be
resubmitted later.  Thanks.

From: Stephen Smalley <sds@epoch.ncsc.mil>

This patch removes the use of nameidata by selinux_inode_permission, as this
appears to be unsafe in certain cases (e.g.  path_walk call from
rpc_lookup_parent), leading to an Oops if d_path is subsequently called by
avc_audit on the (mnt,dentry) pair to generate a pathname for an audit
message.

The change does not affect the ability of SELinux to perform its permission
check (which only requires the inode), only the set of information that is
available for audit messages.  We'll investigate better approaches for the
SELinux audit generation in the future.

From: Stephen Smalley <sds@epoch.ncsc.mil>

This patch reduces the full capability check in the SELinux module for the

This patch fixes the SELinux build for "make O=..." by removing the use of

The dvb-ttpci/av7110 driver needs the firmware_class stuff to work now.

IMHO the appropriate fix is to let the driver automatically select the
firmware loader via Kconfig's SELECT facility.

The dvb-ttusb-dec driver should behave like this, too.  (It currently
depends on the FW_LOADER, which is not "the right thing" (tm))
