[PATCH] fbdev: fix switch to KD_TEXT, enhanced version
Every framebuffer driver relies on the assumption that the set_par()
function of the driver is called before drawing functions and other
functions dependent on the hardware state are executed.
Whenever you switch from X to a framebuffer console for the very first
time, there is a chance that a broken X system has _not_ set the mode to
KD_GRAPHICS, thus the vt and framebuffer code executes a screen redraw and
several other functions before a set_par() is executed. This is believed
to be not a bug of linux but a bug of X/xdm. At least some X releases used
by SuSE and Debian show this behaviour.
There was a 2nd case, but that has been fixed by Antonino Daplas on
10-dec-2005.
This patch allows drivers to set a flag to inform fbcon_switch() that they
prefer a set_par() call on every console switch, working around the
problems caused by the broken X releases.
The flag will be used by the next release of cyblafb and might help other
drivers that assume a hardware state different to the one used by X.
As the default behaviour does not change, this patch should be acceptable
to everybody.

get_user_pages: don't try to follow PFNMAP pages
Nick Piggin points out that a few drivers play games with VM_IO (why?

So make it explicit in get_user_pages() that we don't follow VM_PFNMAP

[PATCH] pcnet32: use MAC address from prom also on powerpc
The CSR contains garbage after a coldboot on RS/6000.
One some systems (like my 44p 270) the MAC address is all FF,
on others (like my B50) it is ff:ff:ff:fd:ff:6b.
It can eventually be fixed by loading pcnet32, set the interface
into the UP state, rmmod pcnet32 and load it again. But this worked
only on the 270.
Only netbooting after a cold start provides the correct MAC address
via prom and CSR. This makes it very unreliable.
I dont know why the MAC is stored in two different places. Remove
the special case for powerpc, which was added in early 2.4 development.

[PATCH] fix in __alloc_bootmem_core() when there is no free page in first node's memory
Hitting BUG_ON() in __alloc_bootmem_core() when there is no free page
available in the first node's memory. For the case of kdump on PPC64
(Power 4 machine), the captured kernel is used two memory regions - memory
for TCE tables (tce-base and tce-size at top of RAM and reserved) and
captured kernel memory region (crashk_base and crashk_size). Since we
reserve the memory for the first node, we should be returning from
__alloc_bootmem_core() to search for the next node (pg_dat).
Currently, find_next_zero_bit() is returning the n^th bit (eidx) when there
is no free page. Then, test_bit() is failed since we set 0xff only for the
actual size initially (init_bootmem_core()) even though rounded up to one
page for bdata->node_bootmem_map. We are hitting the BUG_ON after failing
to enter second "for" loop.

[PATCH] kprobes: fix race in aggregate kprobe registration
When registering multiple kprobes at the same address, we leave a small
window where the kprobe hlist will not contain a reference to the
registered kprobe, leading to potentially, a system crash if the breakpoint
is hit on another processor.
Patch below now automically relpace the old kprobe with the new
kprobe from the hash list.
