The AMBA bus should also use of_device_make_bus_id() when populating device
out of device tree data. This patch makes the function non-static, and
adds a suitable prototype in of_device.hSigned-off-by: Grant Likely

This patch fixes some instances where interrupt specifiers are
dereferenced directly instead of doing a be32_to_cpu() conversion first.Signed-off-by: Grant Likely
-
The flat tree code wasn't fixing the endianness on phandle values when
unflattening the tree, and the code in drivers/of wasn't always doing a
be32_to_cpu before trying to dereference the phandle values. This patch
fixes them.Signed-off-by: Grant Likely

With the current string comparison, a device tree compatible of "foo-bar"
would match as compatible with a driver looking for "foo". This patch
fixes the function to use the of_compat_cmp() macro so that it does the
right thing on all platforms (If sparc ever uses this code, it will still
want the strncasecmp() behaviour).Signed-off-by: Stuart Yoder

This list used was by only two platforms with all other platforms defining an
own list of valid bus id's to pass to of_platform_bus_probe. This patch:i) copies the default list to the two platforms that depended on it (powerpc)
ii) remove the usage of of_default_bus_ids in of_platform_bus_probe
iii) removes the definition of the list from all architectures that defined itPassing a NULL 'matches' parameter to of_platform_bus_probe is still valid; the
function returns no error in that case as the NULL value is equivalent to an
empty list.Signed-off-by: Jonas Bonn

There is an unlikely chance of this situation is occurring, but it is

It is mostly unused now. Sparc has a few defines left in it, but they

Both of_bus_type and of_platform_bus_type are just #define aliases
for the platform bus. This patch removes all references to them and
switches to the of_register_platform_driver()/of_unregister_platform_driver()
API for registering.Subsequent patches will convert each user of of_register_platform_driver()
into plain platform_drivers without the of_platform_driver shim. At which
point the of_register_platform_driver()/of_unregister_platform_driver()
functions can be removed.Signed-off-by: Grant Likely
Acked-by: David S. Miller -
of_platform_bus was being used in the same manner as the platform_bus.
The only difference being that of_platform_bus devices are generated
from data in the device tree, and platform_bus devices are usually
statically allocated in platform code. Having them separate causes
the problem of device drivers having to be registered twice if it
was possible for the same device to appear on either bus.This patch removes of_platform_bus_type and registers all of_platform
bus devices and drivers on the platform bus instead. A previous patch
made the of_device structure an alias for the platform_device structure,
and a shim is used to adapt of_platform_drivers to the platform bus.After all of of_platform_bus drivers are converted to be normal platform
drivers, the shim code can be removed.Signed-off-by: Grant Likely

Fix the security problem in the CIFS filesystem DNS lookup code in which a
malicious redirect could be installed by a random user by simply adding a
result record into one of their keyrings with add_key() and then invoking a
CIFS CFS lookup [CVE-2010-2524].This is done by creating an internal keyring specifically for the caching of
DNS lookups. To enforce the use of this keyring, the module init routine
creates a set of override credentials with the keyring installed as the thread
keyring and instructs request_key() to only install lookup result keys in that
keyring.The override is then applied around the call to request_key().
This has some additional benefits when a kernel service uses this module to
request a key:(1) The result keys are owned by root, not the user that caused the lookup.
(2) The result keys don't pop up in the user's keyrings.
(3) The result keys don't come out of the quota of the user that caused the
lookup.The keyring can be viewed as root by doing cat /proc/keys:
2a0ca6c3 I----- 1 perm 1f030000 0 0 keyring .dns_resolver: 1/4
It can then be listed with 'keyctl list' by root.
# keyctl list 0x2a0ca6c3

In the CONFIG_AUDITSYSCALL fast-path for x86 64-bit system calls,
we can pass a bad return value and/or error indication for the
system call to audit_syscall_exit(). This happens when
TIF_NEED_RESCHED was set as the system call returned, so we went
out to schedule() and came back to the exit-audit fast-path. The
fix is to reload the user return value register from the pt_regs
before using it for audit_syscall_exit().Both the 32-bit kernel's fast path and the 64-bit kernel's 32-bit
system call fast paths work slightly differently, so that they
always leave the fast path entirely to reschedule and don't return
there, so they don't have the analogous bugs.Reported-by: Alexander Viro

Immediately following an exit from the kdb shell the kgdb_connected
variable should be set to zero, unless there are breakpoints planted.
If the kgdb_connected variable is not zeroed out with kdb, it is

In the process of merging kdb to the mainline, the kdb lsmod command

load address of the kernel modules.Signed-off-by: Jason Wessel

The gdbserial protocol handler should return an empty packet instead
of an error string when ever it responds to a command it does not
implement.The problem cases come from a debugger client sending
qTBuffer, qTStatus, qSearch, qSupported.The incorrect response from the gdbstub leads the debugger clients to
not function correctly. Recent versions of gdb will not detach correctly as a result of this behavior.Signed-off-by: Jason Wessel

We only add/remove crtcs at driver load, you cannot remove when
the GPU is running a CS packet since the fd is open, when
GPU hotplugging on radeons actually is needed all this locking
needs a review and I've started re-working kms core locking to deal
with this better. But for now avoid long delays in CS processing when
hotplug detect is happening in a different thread.this fixes a regression introduced with hotplug detection.
