Message:

Merge the CHT pre-integration branch

This branch contains:

• the merge of lp:~adam-hraska+lp/helenos/rcu, which brings:

• a new preemptible kernel RCU variant called A-RCU,
• a preemptible variant of Podzimek's non-preemptible kernel RCU and
• a new variant of usersace RCU,
• a new concurrent hash table (CHT) implementation based on RCU,
• a deployment of CHT in kernel futex handling,
• a deployment of the userspace RCU in the implementation of upgradable futexes,

all described in Adam Hraska's master thesis named Read-Copy-Update
for HelenOS, defended in 2013 at MFF UK; furthemore, the branch
fixes two synchronization bugs in condvars and waitq, respectively:

• revid:adam.hraska+hos@gmail.com-20121116144921-3to9u1tn1sg07rg7
• revid:adam.hraska+hos@gmail.com-20121116173623-km7gwtqixwudpe66

• build fixes required to pass make check
• overhaul of ia64 and sparc64 trap handling, to allow exc_dispatch() to be used now when the kernel is more picky about CPU state accounting
• an important fix of the sparc64/sun4v preemptible trap handler
• various other fixes of issues discovered on non-x86 architectures
