    • Add lame aarch64 userspace support. · 26f60603
      We don't (can't) have runtime L1 cache size detection on aarch64 without
      help.  Of course, line size is always 64 bytes (and that can be found at
      runtime); but the total L1 dcache size is not discoverable unless the
      kernel (or something else at EL0) has flipped the ECT bit in the system
      control register.  This could well be why getconf LEVEL1_DCACHE_SIZE
      fails.  In any case, I can't see how it would work.
      So, abuse the fact that no aarch64 impl has L1 dcache < 32KB and be happy.

    • Bug in kernel platform trylock definition. · 4b5f7849
      Unlike other kernel functions, mutex_trylock returns 1 on sucess
      and 0 on error. The double negations were inverting the interpretation
      of the result. (It still worked because on the first attempt, we
      interpreted as a failure and tried again; on the second attempt, it
      was really a failure to take the lock but we interpreted as a

    • Re-work the old ops to use the new CDT interface · fe68b750
      This commit does three main things:
        1. Full CDT reference counting. When CDT locks are acquired, all
           intermediate root's reference counts are update safely.
        2. Re-factor's the operations to use two generic locking routines with
           special handlers (binop, and unop). This removes a lot of code duplication
           which made adding the locking code much easier, and should help
           prevent bugs.
        3. Removes the `delete` callback, now `delete` will be called whenever
           a cnode is created. It's the object's decision if this requires a
           memory free or not. Also adds three new callbacks:
             * `grant(src, dst)`: called when a grant from src -> dst happens.
                Only the handler for `src` is called.
             * `derive_src(src, dst)`: called on `src` when dst is derived from src.
             * `derive_dst(src, dst)`: called on `dst` when dst is derived from src.
          Objects are now responsible for doing some sort of reference
          counting in the grant and delete callbacks to prevent leaks. The
          grant and derive callbacks will also be the main hooks for capnet.

    • Add kernel build fixes. · d6dc6cb7
      I got rid of the KERNEL_HEADERS_INSTALL thing. Kind of silly. The
      user is just expected to set their prefix right. We still have to
      do a hook in order to install the kernel-specific stuff. libcap.a
      and libcap.ko (kernel binaries) go in prefix/lib.
