Perform the qemu special case only when the binary seems the same as
our own executable.
This is enough for my use case (docker and runc) where the involved
qemu binaries are always for the same arch.

dockerd makes runc invoke dockerd using /proc/$pid/exe.
This commit makes it work when both of dockerd and runc are
emulated by qemu linux-user.
In that case, we (the qemu interpreting runc) need to invoke the
real executable (dockerd), where /proc/$pid/exe in question is
the qemu command
Refactor to prepare the special cases for /proc/$pid/exe where
pid is not the calling process.

This patchset includes a few patches marked [!MERGE],
which are not for the upsteam merge. They are included here just to

In this RFC patch series, I propose an initial cache modelling TCG
plugin. As of now, it models separate L1 data cache and L1 instruction
cache. It supports three eviction policies: LRU, random, and FIFO. Once
a policy is chosen, it's used for both instruction and data caches.

Added a cache modelling plugin that uses a static configuration used in
many of the commercial microprocessors and uses random eviction policy.
