The function paravirt_ops_setup() has been refering the
variable no_timer_check, which is a __initdata. Thus generates
the following warning. paravirt_ops_setup() function is called
from kvm_guest_init() which is a __init function. So to fix
this we mark paravirt_ops_setup as __init.The sections-check output that warned us about this was:
LD arch/x86/built-in.o
WARNING: arch/x86/built-in.o(.text+0x166ce): Section mismatch in
reference from the function paravirt_ops_setup() to the variable
.init.data:no_timer_check
The function paravirt_ops_setup() references
the variable __initdata no_timer_check.
This is often because paravirt_ops_setup lacks a __initdata
annotation or the annotation of no_timer_check is wrong.Signed-off-by: Rakib Mullick

It's simpler and more straightforward.Backward fixmaps seems to be used by both x86 32 and 64.
It's really rare but a nasty bug, because it only hurts when
instructions to patch are crossing a page boundary. If this
happens, the fixmap write accesses will spill on the following
fixmap, which may very well crash the system. And this does not
crash the system, it could leave illegal instructions in place.
Thanks Masami for finding this.It seems to have crept into the 2.6.30-rc series, so this calls
for a -stable inclusion.Signed-off-by: Mathieu Desnoyers

…tl HDIO_OBSOLETE_IDENTITY
This patch fixes a memory overrun in function ide_get_identity_ioctl() which
chooses the size of a memory buffer depending on the ioctl command that led
to the function call, however, passes that buffer to a function which needs the
buffer size to be always chosen unconditionally.Due to conditional compilation the memory overrun can only happen on big endian
machines. The error can be triggered using ioctl HDIO_OBSOLETE_IDENTITY. Usage
of ioctl HDIO_GET_IDENTITY is safe.Signed-off-by: Christian Engelmayer <christian.engelmayer@frequentis.com>

commit 2f0d0fd2a605666d38e290c5c0d2907484352dc4 ("ide-acpi: cleanup
do_drive_get_GTF()") didn't account for the lack of hwif->acpidata
check in generic_ide_suspend() [ indirect user of do_drive_get_GTF()
through ide_acpi_exec_tfs() ] resulting in broken resume when ACPI
support is enabled but ACPI data is unavailable.Fix it by adding ide_port_acpi() helper for checking if port needs
ACPI handling and cleaning generic_ide_{suspend,resume}() to use it
instead of hiding hwif->acpidata and ide_noacpi checks in IDE ACPI
helpers (this should help in preventing similar bugs in the future).While at it:

Currently we reinit the ldisc on final tty close which is what the old code
did to ensure that if the device retained its termios settings then it had the
right ldisc. tty_ldisc_reinit does that but also leaves us with the reset
ldisc reference which is then leaked.At this point we know the port will be recycled so we can kill the ldisc
off completely rather than try and add another ldisc free up when the kref
count hits zero.At this point it is safe to keep the ldisc closed as tty_ldisc waiting
methods are only used from the user side, and as the final close we are
the last such reference. Interrupt/driver side methods will always use the
non wait version and get back a NULL.Found with kmemleak and investigated/identified by Catalin Marinas.

The new fsnotify infrastructure (starting at 90586523) causes an oops in
spufs, where we populate a directory with files before instantiating the
directory itself. The new changes seem to have introduced an assumption
that a dentry's parent will be positive when instantiating.This change makes it once again possible to d_instantiate a dentry
with a negative parent, and brings __fsnotify_d_instantiate() into
line with inotify_d_instantiate(), which already has this NULL check.Signed-off-by: Jeremy Kerr
