- Mark the default colormaps read-only, as nobody should be allowed to
modify them
- Additionally mark color values as __read_mostly since they will only be
modified (very seldom) by fb_invert_cmaps()
- Add named C99-initializers in fb_cmap structs and use the ARRAY_SIZE()
macro

This patch adds support for stn displays on the s3c2410 arm SoC.
The LCD type is choosen by a new field in the s3c2410fb_mach_info structure
and its value is the value of the PNRMODE bits. This worth to be noted as
a value of 0 means that you configure a 4 bit dual scan stn display.

Refactor the ipc sysctl support so that it is simpler, more readable, and
prepares for fixing the bug with the wrong values being returned in the
sys_sysctl interface.
The function proc_do_ipc_string() was misnamed as it never handled strings.
It's magic of when to work with strings and when to work with longs belonged
in the sysctl table. I couldn't tell if the code would work if you disabled
the ipc namespace but it certainly looked like it would have problems.

The problem: When using sys_sysctl we don't read the proper values for the
variables exported from the uts namespace, nor do we do the proper locking.
This patch introduces sysctl_uts_string which properly fetches the values and
does the proper locking.

The binary interface to the namespace sysctls was never implemented resulting
in some really weird things if you attempted to use sys_sysctl to read your
hostname for example.
This patch series simples the code a little and implements the binary sysctl
interface.
In testing this patch series I discovered that our 32bit compatibility for the
binary sysctl interface is imperfect. In particular KERN_SHMMAX and
KERN_SMMALL are size_t sized quantities and are returned as 8 bytes on to
32bit binaries using a x86_64 kernel. However this has existing for a long
time so it is not a new regression with the namespace work.
Gads the whole sysctl thing needs work before it stops being easy to shoot
yourself in the foot.
Looking forward a little bit we need a better way to handle sysctls and
namespaces as our current technique will not work for the network namespace.
I think something based on the current overlapping sysctl trees will work but
the proc side needs to be redone before we can use it.
This patch:
Introduce get_uts() and put_uts() (used later) and remove most of the special
cases for when UTS namespace is compiled in.

This patch provides stacktrace filtering feature.
The stacktrace filter allows failing only for the caller you are
interested in.
For example someone may want to inject kmalloc() failures into
only e100 module. they want to inject not only direct kmalloc() call,
but also indirect allocation, too.
- e100_poll --> netif_receive_skb --> packet_rcv_spkt --> skb_clone
--> kmem_cache_alloc
This patch enables to detect function calls like this by stacktrace
and inject failures. The script Documentaion/fault-injection/failmodule.sh
helps it.
The range of text section of loaded e100 is expected to be
[/sys/module/e100/sections/.text, /sys/module/e100/sections/.exit.text)
So failmodule.sh stores these values into /debug/failslab/address-start
and /debug/failslab/address-end. The maximum stacktrace depth is specified
by /debug/failslab/stacktrace-depth.
Please see the example that demonstrates how to inject slab allocation
failures only for a specific module
in Documentation/fault-injection/fault-injection.txt

This patch set provides some fault-injection capabilities.
- kmalloc() failures
- alloc_pages() failures
- disk IO errors
We can see what really happens if those failures happen.
In order to enable these fault-injection capabilities:
1. Enable relevant config options (CONFIG_FAILSLAB, CONFIG_PAGE_ALLOC,
CONFIG_MAKE_REQUEST) and if you want to configure them via debugfs,
enable CONFIG_FAULT_INJECTION_DEBUG_FS.
2. Build and boot with this kernel
3. Configure fault-injection capabilities behavior by boot option or debugfs
- Boot option
failslab=
fail_page_alloc=
fail_make_request=
- Debugfs
/debug/failslab/*
/debug/fail_page_alloc/*
/debug/fail_make_request/*
Please refer to the Documentation/fault-injection/fault-injection.txt
for details.
4. See what really happens.
