Add a scrollback buffers for each VGA console. The benefit is that
the scrollback history is not flushed when switching between consoles
but is persistent.
The buffers are allocated on demand when a new console is opened.
This breaks tools like clear_console that rely on flushing the

Several modern devices, such as PC/104 cards, are expected to run on
modern systems via an ISA bus interface. Since ISA is a legacy interface

basis.

This patch set introduce the GCC plugin infrastructure with examples for testing
and documentation.
GCC plugins are loadable modules that provide extra features to the compiler.
They are useful for runtime instrumentation and static analysis.
The infrastructure supports all gcc versions from 4.5
Infrastructure for building independent shared library targets.
Based on work created by the PaX Team.

This patch allows to build the whole kernel with GCC plugins. It was ported from
grsecurity/PaX. The infrastructure supports building out-of-tree modules and
building in a separate directory. Cross-compilation is supported too.
Currently the x86, arm, arm64 and uml architectures enable plugins.

Add "srcline_from" and "srcline_to" branch sort keys that allow to show
the source lines of a branch.
That makes it much easier to track down where particular branches happen
in the program, for example to examine branch mispredictions, or to
associate it with cycle counts:

record__mmap_read() writes data from ring buffer into perf.data. 'head'
is maintained by the kernel, points to the last written record.
'old' is maintained by perf, points to the record read in previous
round. record__mmap_read() saves data from 'old' to 'head' to
perf.data.

Add a very simple plugin to demonstrate the GCC plugin infrastructure. This GCC
plugin computes the cyclomatic complexity of each function.
The complexity M of a function's control flow graph is defined as:
M = E - N + 2P
where
E = the number of edges
N = the number of nodes
P = the number of conn
The sancov gcc plugin inserts a __sanitizer_cov_trace_pc() call
at the start of basic blocks.
This plugin is a helper plugin for the kcov feature. It supports
all gcc versions with plugin support (from gcc-4.5 on).
It is based on the gcc commit "Add fuzzing coverage support" by Dmitry Vyukov

Add a fd field into struct perf_mmap so that perf can track the mmap fd.

When record__mmap_read() requires data more than the size of ring
buffer, drop those data to avoid accessing invalid memory.
This can happen when reading from overwritable ring buffer, which
should be avoided. However, check this for robustness.

Noticed when the 'setsockopt' 'fd' arg wasn't being formatted via
the SCA_FD beautifier, so just remove the setting of "fd" args to
SCA_FD and do it when reading the syscall info, like we do for
args of type "pid_t", i.e. "fd" as the name should be enough as

I would like to introduce the latent_entropy gcc plugin. This plugin mitigates

This plugin mitigates the problem of the kernel having too little entropy during
and after boot for generating crypto keys.
It creates a local variable in every marked function. The value of this
variable is
modified by randomly chosen operations (add, xor and rol) and
random values (gcc generate
These functions have been selected because they are init functions or
are called at random times or they have variable loops.
