This testcase results in an mlock() failure with errno 14 that is EFAULT,
but it has nowhere been specified that mlock() will return EFAULT. When I
tested the same on older kernels like 2.6.18, I got the correct result i.e
errno 12 (ENOMEM).
I think in source code mlock(2), setting errno ENOMEM has been missed in
do_mlock() , on mlock_fixup() failure.
SUSv3 requires the following behavior frmo mlock(2).
[ENOMEM]
Some or all of the address range specified by the addr and
len arguments does not correspond to valid mapped pages
in the address space of the process.
[EAGAIN]
Some or all of the memory identified by the operation could not
be locked when the call was made.
This rule isn't so nice and slighly strange. but many people think
POSIX/SUS compliance is important.

atmel_spi: fix hang due to missed interrupt
For some time my at91sam9260 board with JFFS2 on serial flash (m25p80)
would hang when accessing the serial flash and SPI bus. Slowing the SPI
clock down to 9 MHz reduced the occurrence of the hang from "always"
during boot to a nuisance level that allowed other SW development to
continue. Finally had to address this issue when an application stresses
the I/O to always cause a hang.
Hang seems to be caused by a missed SPI interrupt, so that the task ends
up waiting forever after calling spi_sync(). The fix has 2 parts. First
is to halt the DMA engine before the "current" PDC registers are loaded.
This ensures that the "next" registers are loaded before the DMA operation
takes off. The second part of the fix is a kludge that adds a
"completion" interrupt in case the ENDRX interrupt for the last segment of
the DMA chaining operation was missed.
The patch allows the SPI clock for the serial flash to be increased from 9
MHz to 15 MHz (or more?). No hangs or SPI overruns were encountered.
Haavard: while this patch does indeed improve things, I still see overruns
and CRC errors on my NGW100 board when running the DataFlash at 10 MHz.
However, I think some improvement is better than nothing, so I'm passing
this on for inclusion in 2.6.27.

mm: dont clear PG_uptodate on truncate/invalidate
Brian Wang reported that a FUSE filesystem exported through NFS could
return I/O errors on read. This was traced to splice_direct_to_actor()
returning a short or zero count when racing with page invalidation.
However this is not FUSE or NFSD specific, other filesystems (notably
NFS) also call invalidate_inode_pages2() to purge stale data from the
cache.
If this happens while such pages are sitting in a pipe buffer, then
splice(2) from the pipe can return zero, and read(2) from the pipe can
return ENODATA.
The zero return is especially bad, since it implies end-of-file or
disconnected pipe/socket, and is documented as such for splice. But
returning an error for read() is also nasty, when in fact there was no
error (data becoming stale is not an error).
The same problems can be triggered by "hole punching" with
madvise(MADV_REMOVE).
Fix this by not clearing the PG_uptodate flag on truncation and
invalidation.

embedded: fix vc_translate operator precedence
This fixes a bug in operator precedence in the newly introduced vc_translate
macro. Without this fix, the translation of some characters on the
kernel console is garbled.
This patch was copied to the e-mail list previously for testing. Now,
all reports confirm that it works, so this is an official post for
application.

dual license ftrace.txt
I asked legal about the licensing of ftrace.txt, and they told me that,
unless the Documentation directory is specifically set up to handle non
GPL licenses (which it does not appear to be), then it would be best to
put ftrace.txt under the GPL.
This patch adds a dual license to ftrace.txt such that it is under both
the FDL and the GPL.

try harder to load tty ldisc driver
Currently function tty_ldisc_get() tries to load an ldisc driver module
only when tty_ldisc_try_get() returns -EAGAIN. This happens only if
module is being unloaded. If ldisc module is not loaded
tty_ldisc_try_get() returns -EINVAL and this case is not handled in
tty_ldisc_get(), so request_module() is not called.
Attached patch fixes this by calling request_module() if
tty_ldisc_try_get() returned any error code.
I discovered this when my UMTS modem stopped working with 2.6.27-rc1
because module ppp_async was not loaded.

mm/hugetlb: don't crash when HPAGE_SHIFT is 0
Some platform decide whether they support huge pages at boot time. On
these, such as powerpc, HPAGE_SHIFT is a variable, not a constant, and is
set to 0 when there is no such support.
The patches to introduce multiple huge pages support broke that causing
the kernel to crash at boot time on machines such as POWER3 which lack
support for multiple page sizes.

Same problem have

When defining a symbol in vmlinux.lds, use the VMLINUX_SYMBOL macro.
VMLINUX_SYMBOL adds a prefix charactor.
You can't just use straight symbol names in common header files as they
dont take into consideration weird arch-specific ABI conventions. in the
case of Blackfin/h8300, the ABI dictates that any C-visible symbols have
an underscore prefixed to them. Thus all symbols in vmlinux.lds.h need to
be wrapped in VMLINUX_SYMBOL() so that each arch can put hide this magic
in their own files.

PNP: fix formatting of dbg_pnp_show_resources() output
Each resource should be printed on its own line, so start snprintf'ing
at the beginning of the buffer every time through the loop.
Also, use scnprintf() rather than snprintf() when building up the
buffer to print. scnprintf() returns the number of characters actually
written into the buffer (not including the trailing NULL).
snprintf() returns the number of characters that *would be* written,
assuming everything would fit in the buffer. That's nice if we want to
resize the buffer to make sure everything fits, but in this case, I
just want to keep from overflowing the buffer, and it's OK if the
output is truncated.
Using snprintf() meant that my "len" could grow to be more than the
the buffer size, which makes "sizeof(buf) - len" negative, which causes
this alarming WARN_ON:

tracehook: fix exit_signal=0 case
My commit
2b2a1ff64afbadac842bbc58c5166962cf4f7664 introduced a regression
(sorry about that) for the odd case of exit_signal=0 (e.g. clone_flags=0).
This is not a normal use, but it's used by a case in the glibc test suite.
Dying with exit_signal=0 sends no signal, but it's supposed to wake up a
parent's blocked wait*() calls (unlike the delayed_group_leader case).
This fixes tracehook_notify_death() and its caller to distinguish a
"signal 0" wakeup from the delayed_group_leader case (with no wakeup).

[IA64] Move include/asm-ia64 to arch/ia64/include/asm
After moving the the include files there were a few clean-ups:
1) Some files used #include <asm-ia64/xyz.h>, changed to <asm/xyz.h>
2) Some comments alerted maintainers to look at various header files to
make matching updates if certain code were to be changed. Updated these
comments to use the new include paths.
3) Some header files mentioned their own names in initial comments. Just
deleted these self references.

au1xmmc: raise segment size limit.
Raise the DMA block size limit from 2048 bytes to the maximum supported
by the DMA controllers on the chip (64KB on Au1100, 4MB on Au1200).
This gives a very small performance boost and apparently fixes an oops

Thanks for your detailed explanation.

kernel/audit.c control character detection is off-by-one
Hello,
According to my understanding there is an off-by-one bug in the
function:
audit_string_contains_control()
in:
kernel/audit.c
Patch is included.
I do not know from how many places the function is called from, but for
example, SELinux Access Vector Cache tries to log untrusted filenames via
call path:
avc_audit()
audit_log_untrustedstring()
audit_log_n_untrustedstring()
audit_string_contains_control()
If audit_string_contains_control() detects control characters, then the
string is hex-encoded. But the hex=0x7f dec=127, DEL-character, is not
detected.
I guess this could have at least some minor security implications, since a
user can create a filename with 0x7f in it, causing logged filename to
possibly look different when someone reads it on the terminal.

Which stayed unnoticed for a long time because, surprise, idr_remove()

All of this due to "| ~MAX_ID_MASK" in release_inode_number().
I still don't understand how it's supposed to work, because "| ~MASK"
is not an inversion for "& MAX" operation.
