Topcliff PCH is the platform controller hub that is going to be used in Intel's upcoming general embedded platform. All IO peripherals in Topcliff PCH are actually devices sitting on AMBA bus.

2010-10-08isdn: strcpy() => strlcpy()Dan Carpenter
setup.phone and setup.eazmsn are 32 character buffers. rcvmsg.msg_data.byte_array is a 48 character buffer. sc_adapter[card]->channel[rcvmsg.phy_link_no - 1].dn is 50 chars. The rcvmsg struct comes from the memcpy_fromio() in receivemessage(). I guess that means it's data off the wire. I'm not very familiar with this code but I don't see any reason to assume these strings are NULL terminated. Also it's weird that "dn" in a 50 character buffer but we only seem to use 32 characters. In drivers/isdn/sc/scioc.h, "dn" is only a 49 character buffer. So potentially there is still an issue there. The important thing for now is to prevent the memory corruption.

2010-10-08drm/i915: Prevent module unload to avoid random memory corruptionChris Wilson
The i915 driver has quite a few module unload bugs, the known ones at least have fixes that are targeting 2.6.37. However, in order to maintain a stable kernel, we should prevent this known random memory corruption following driver unload. This should have very low impact on normal users who are unlikely to need to unload the i915 driver.

Recent clean of i.MX devices registration changed the i2C bus number selected for our platform (Freescale start peripheral ID at 1, kernel now start it at 0 so i.MX27's i2c 1 is kernel's i2c 0).

2010-10-08ARM: hotplug cpu: move secondary_startup, __enable_mmu to cpuinitRussell King
Move these two functions, both of which are required for secondary CPU booting, into the cpuinit section. Ensure bad processors call __error_p for better diagnostics, rather than just __error. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-10-08ARM: hotplug cpu: ensure that __enable_mmu is identity mappedRussell King
__enable_mmu is required to be executed in an identity mapped region to ensure that variances in CPUs do not cause a crash. We currently achieve this by assuming that it will be co-located with __create_page_tables. With hotplug CPU support, this assumption becomes invalid. Implement a better solution which ensures that it will be appropriately mapped no matter where it is placed. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
