Commit 566f74f6b2f8b85d5b8d6caaf97e5672cecd3e3e had a change that
incorrectly modified ebase. This backs out the lines that modified
ebase.
In addition, the ebase exception vector is now allocated with correct
alignment and the ebase register updated according to the architecture
specification.
Based on original patch by David VomLehn <dvomlehn@cisco.com>.

dma_cache_wback_inv() expects virtual address, but physical was provided
due to translation via plat_dma_addr_to_phys().

Currently the driver just read "reg" property for constructing MDIO
bus IDs, but this won't work when we'll start using "ranges = <>" in
the device tree, so this will pop up:

With a sufficiently new compiler and binutils, code which wasn't
previously generating .eh_frame sections has begun to. Certain
architectures (powerpc, in this case) may generate unexpected relocation
formats in response to this, preventing modules from loading.
While the new relocation types should probably be handled, revert to the
previous behaviour with regards to generation of .eh_frame sections.
(This was reported against Fedora, which appears to be the only distro
doing any building against gcc-4.4 at present: RH bz#486545.)

See http://bugzilla.kernel.org/show_bug.cgi?id=12911
copy_signal() copies signal->rlim, but RLIMIT_CPU is "lost". Because
posix_cpu_timers_init_group() sets cputime_expires.prof_exp = 0 and thus
fastpath_timer_check() returns false unless we have other cpu timers.
This is the minimal fix for 2.6.29 (tested) and 2.6.28. The patch is not
optimal, we need further cleanups here. With this patch update_rlimit_cpu()
is not really needed, but I don't think it should be removed.
The proper fix (I think) is:
- set_process_cpu_timer() should just start the cputimer->running
logic (it does), no need to change cputime_expires.xxx_exp
- posix_cpu_timers_init_group() should set ->running when needed
- fastpath_timer_check() can check ->running instead of
task_cputime_zero(signal->cputime_expires)

This patch fixes bug #12208:
Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=12208
Subject : uml is very slow on 2.6.28 host
This turned out to be not a scheduler regression, but an already
existing problem in ptrace being triggered by subtle scheduler
changes.
The problem is this:
- task A is ptracing task B
- task B stops on a trace event
- task A is woken up and preempts task B
- task A calls ptrace on task B, which does ptrace_check_attach()
- this calls wait_task_inactive(), which sees that task B is still on the runq
- task A goes to sleep for a jiffy
- ...
Since UML does lots of the above sequences, those jiffies quickly add
up to make it slow as hell.
This patch solves this by not rescheduling in read_unlock() after
ptrace_stop() has woken up the tracer.
Thanks to Oleg Nesterov and Ingo Molnar for the feedback.

Impact: section mismatch fix
Ingo reports these warnings:

> The function dmi_alloc() references

dmi_alloc() is a static inline, and so should be immune to this
kind of error. But force it to be inlined and make it __init
anyway, just to be extra sure.
All of dmi_alloc()'s callers are already __init.

This patchs adds support of modification of the used logger via sysctl.
It can be used to change the logger to module that can not use the bind
operation (ipt_LOG and ipt_ULOG). For this purpose, it creates a
directory /proc/sys/net/netfilter/nf_log which contains a file
per-protocol. The content of the file is the name current logger (NONE if
not set) and a logger can be setup by simply echoing its name to the file.
By echoing "NONE" to a /proc/sys/net/netfilter/nf_log/PROTO file, the
logger corresponding to this PROTO is set to NULL.
