When we pull the PPP protocol off the skb, we forgot to update the
hardware RX checksum. This may lead to messages such asdsl0: hw csum failure.
Similarly, we need to clear the hardware checksum flag when we use
the existing packet to store the decompressed result.Signed-off-by: Herbert Xu

Allocate memory for read-gathering at open time, when it is known just how
much memory is needed. This avoids wasting kernel memory when the real packet
size is smaller than the maximum packet size supported by the driver. This is
always the case when using DVD discs.Signed-off-by: Peter Osterlund

The pktcdvd driver was using an 8 bit field to store the packet length
obtained from the disc track info. This causes it to overflow packet length
values of 128KB or more. I changed the field to 32 bits to fix this.The pktcdvd driver defaulted to its maximum allowed packet length when it
detected a 0 in the track info field. I changed this to fail the operation
and refuse to access the media. This seems more sane than attempting to
access it with a value that almost certainly will not work.Signed-off-by: Peter Osterlund

percpu_data blindly allocates bootmem memory to store NR_CPUS instances of
cpudata, instead of allocating memory only for possible cpus.As a preparation for changing that, we need to convert various 0 -> NR_CPUS
loops to use for_each_cpu().(The above only applies to users of asm-generic/percpu.h. powerpc has gone it
alone and is presently only allocating memory for present CPUs, so it's
currently corrupting memory).Signed-off-by: Eric Dumazet

I just purchased a HighPoint Rocket 1520 SATA controller. There seems to
be no libata driver (yet), but there is an ide driver, hpt366. When the
driver gets loaded, it causes a kernel NULL pointer dereference in
pci_bus_clock_list. It seems to be because the driver is waiting for clock
stabilization in init_hpt37x() which never comes. The driver just
continues on with the pci drvdata set to NULL, instead of a valid clock
entry. The following patch prevents the NULL dereference from happening,
but instead exit with an error.Acked-by: Bartlomiej Zolnierkiewicz

This patch stops CompactFlash devices being marked as removable. They are
not removable (as defined by Linux) as the media and device are
inseparable. When a card is removed, the whole device is removed from the
system and never sits in a media-less state.This stops some nasty udev device creation/destruction loops.
Further, once this change is made, there is no need for ide to can be
removed from ide_drive_t.Signed-off-by: Richard Purdie

fails to list the most important/widespread (IMHO) device: Compact Flash
PCMCIA adapters.This incomplete description recently caused me to deselect the ide_cs

actually enabled it some years ago.Updates:

While looking to the report by Coverity in ipmi, I came across the
following issue:The IPMI message handler relies on two defines which are the same -one in
include/linux/ipmi.h
#define IPMI_NUM_CHANNELS 0x10
and one in drivers/char/ipmi/ipmi_msghandler.
#define IPMI_MAX_CHANNELS 16
These are used interchangeably in ipmi_msghandler.c, but since the array
addr->channels[] is of size IPMI_MAX_CHANNELS, I have made a patch that
uses IPMI_MAX_CHANNELS for all the checks for the array index.NOTE: You could probably remove the line that defines IPMI_NUM_CHANNELS
from ipmi.h, or move IPMI_MAX_CHANNELS to ipmi.hSigned-off-by: Jayachandran C.

With Eric's "i386: Add a temporary to make put_user more type safe" patch we
get a pile of warnings out of ip2m1in.c:drivers/char/ip2main.c: In function `ip2_ipl_ioctl':
drivers/char/ip2main.c:2910: warning: assignment makes integer from pointer without a cast
drivers/char/ip2main.c:2911: warning: assignment makes integer from pointer without a cast
drivers/char/ip2main.c:2912: warning: assignment makes integer from pointer without a cast
etc.This ioctl is copying the kernel virtual address of a large number of
functions out to userspace. Heaven knows why.Rather than fixing the warnings, I think we'll just nuke that code.
The patch also fixes a couple of `defined but not used' warnings.

Change locking in the new tty buffering facility from using tty->read_lock,
which is currently ignored by drivers and thus ineffective. New locking
uses a new tty buffering specific lock enforced centrally in the tty
buffering code.Two drivers (esp and cyclades) are updated to use the tty buffering
functions instead of accessing tty buffering internals directly. This is
required for the new locking to work.Minor checks for NULL buffers added to

The patch implements cpu topology exportation by sysfs.
Items (attributes) are similar to /proc/cpuinfo.
1) /sys/devices/system/cpu/cpuX/topology/physical_package_id:
represent the physical package id of cpu X;
2) /sys/devices/system/cpu/cpuX/topology/core_id:
represent the cpu core id to cpu X;
3) /sys/devices/system/cpu/cpuX/topology/thread_siblings:
represent the thread siblings to cpu X in the same core;
4) /sys/devices/system/cpu/cpuX/topology/core_siblings:
represent the thread siblings to cpu X in the same physical package;To implement it in an architecture-neutral way, a new source file,
driver/base/topology.c, is to export the 5 attributes.If one architecture wants to support this feature, it just needs to
implement 4 defines, typically in file include/asm-XXX/topology.h.
The 4 defines are:
#define topology_physical_package_id(cpu)
#define topology_core_id(cpu)
#define topology_thread_siblings(cpu)
#define topology_core_siblings(cpu)The type of **_id is int.
The type of siblings is cpumask_t.To be consistent on all architectures, the 4 attributes should have
deafult values if their values are unavailable. Below is the rule.1) physical_package_id: If cpu has no physical package id, -1 is the
default value.2) core_id: If cpu doesn't support multi-core, its core id is 0.
3) thread_siblings: Just include itself, if the cpu doesn't support
HT/multi-thread.4) core_siblings: Just include itself, if the cpu doesn't support
multi-core and HT/Multi-thread.So be careful when declaring the 4 defines in include/asm-XXX/topology.h.
If an attribute isn't defined on an architecture, it won't be exported.
Thank Nathan, Greg, Andi, Paul and Venki.
