The floating point functions are here rather than compiler-rt because the libc softfloat code allows us to set the rounding mode.

…ys of interrupt counts and names, by making the names into an array of fixed-length strings that can be directly indexed. This eliminates extra memory accesses on every interrupt to increment the counts. As a side effect, it also fixes a bug that would corrupt the names data if a name was longer than MAXCOMLEN, which led to incorrect vmstat -i output. Approved by: cognet (mentor)

The threaded rtld lock implementation is faster even in the single-threaded case because it postpones signal handlers via THR_CRITICAL_ENTER and THR_CRITICAL_LEAVE instead of calling sigprocmask(2). As a result, exception handling becomes faster in single-threaded applications linked with libthr. Reviewed by: kib
This brings in __aeabi_lcmp and __aeabi_ulcmp. It also fixes the spelling of __aeabi_f2lz. Both changes originated on the arm_eabi project branch.

Please note that by enabling this option (default is disabled), the system could potentionally have silent data corruption if the server crashes before write is committed to non-volatile storage, as the client side have no way to tell if the data is already written.

two upcoming features: semi-transparent mode: when a device is opened in this mode, the user program will be able to mark slots that must be forwarded to the "other" side (i.e. from NIC to host stack, or viceversa), and the forwarding will occur automatically at the next netmap syscall. This saves the need to open another file descriptor and do the forwarding manually. direct-forwarding mode: when operating with a VALE port, the user can specify in the slot the actual destination port, overriding the forwarding decision made by a lookup of the destination MAC. This can be useful to implement packet dispatchers. No API changes will be introduced. No new functionality in this patch yet.
CPUs exhibit bad behavior if this is done (Intel Errata AAJ3, hangs on Pentium-M, and trashing of the local APIC registers on a VIA C7). The local APIC is implicitly mapped UC already via MTRRs, so the clflush isn't necessary anyway. MFC after: 2 weeks
