2010-10-12drm/radeon/kms: Silent spurious error messageJean Delvare
I see the following error message in my kernel log from time to time: radeon 0000:07:00.0: ffff88007c334000 reserve failed for wait radeon 0000:07:00.0: ffff88007c334000 reserve failed for wait After investigation, it turns out that there's nothing to be afraid of and everything works as intended. So remove the spurious log message. Signed-off-by: Jean Delvare <khali@linux-fr.org> Reviewed-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2010-10-12drm/radeon/kms: avoid corner case issue with unmappable vram V2Jerome Glisse
We should not allocate any object into unmappable vram if we have no means to access them which on all GPU means having the CP running and on newer GPU having the blit utility working. This patch limit the vram allocation to visible vram until we have acceleration up and running. Note that it's more than unlikely that we run into any issue related to that as when acceleration is not woring userspace should allocate any object in vram beside front buffer which should fit in visible vram. V2 use real_vram_size as mc_vram_size could be bigger than the actual amount of vram [airlied: fixup r700_cp_stop case] Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2010-10-11tg3: restore rx_dropped accountingEric Dumazet
commit 511d22247be7 (tg3: 64 bit stats on all arches), overlooked the rx_dropped accounting. We use a full "struct rtnl_link_stats64" to hold rx_dropped value, but forgot to report it in tg3_get_stats64(). Use an "unsigned long" instead to shrink "struct tg3" by 176 bytes, and report this value to stats readers. Increment rx_dropped counter for oversized frames.

Stanse found that ia_init_one locks a spinlock and inside of that it calls ia_start which calls: * request_irq * tx_init which does kmalloc(GFP_KERNEL) Both of them can thus sleep and result in a deadlock.

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.
