* Net: bluetooth: Makefile: Remove deprecated kbuild goal definitionsTracey Dent2010-11-22

* pktgen: allow faster module unloadEric Dumazet2010-11-21
| | | | | | | | | | | | | | | | Unloading pktgen module needs ~6 seconds on a 64 cpus machine, to stop 64 kthreads. Add a pktgen_exiting variable to let kernel threads die faster, so that kthread_stop() doesnt have to wait too long for them. This variable is not tested in fast path. Note : Before exiting from pktgen_thread_worker(), we must make sure kthread_stop() is waiting for this thread to be stopped, like its done in kernel/softirq.c Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

Do not allow for initiating communication if our secondary HT40 channel has is either disabled, has a passive scan flag, a no-ibss flag or is a radar channel.

* | | filter: use reciprocal divideEric Dumazet2010-11-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At compile time, we can replace the DIV_K instruction (divide by a constant value) by a reciprocal divide. At exec time, the expensive divide is replaced by a multiply, a less expensive operation on most processors.

* | | filter: optimize sk_run_filterEric Dumazet2010-11-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove pc variable to avoid arithmetic to compute fentry at each filter instruction. Jumps directly manipulate fentry pointer. As the last instruction of filter[] is guaranteed to be a RETURN, and all jumps are before the last instruction, we dont need to check filter bounds (number of instructions in filter array) at each iteration, so we remove it from sk_run_filter() params. On x86_32 remove f_k var introduced in commit 57fe93b374a6b871 (filter: make sure filters dont read uninitialized memory) Note : We could use a CONFIG_ARCH_HAS_{FEW|MANY}_REGISTERS in order to avoid too many ifdefs in this code. This helps compiler to use cpu registers to hold fentry and A accumulator. On x86_32, this saves 401 bytes, and more important, sk_run_filter() runs much faster because less register pressure (One less conditional branch per BPF instruction) # size net/core/filter.o net/core/filter_pre.o text data bss dec hex filename 2948 0 0 2948 b84 net/core/filter.o 3349 0 0 3349 d15 net/core/filter_pre.o on x86_64 : # size net/core/filter.o net/core/filter_pre.o text data bss dec hex filename 5173 0 0 5173 1435 net/core/filter.o 5224 0 0 5224 1468 net/core/filter_pre.o Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Acked-by: Changli Gao <xiaosuo@gmail.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC (rightfully) complains that: drivers/atm/fore200e.c:614:5: warning: operation on 'cmdq->head' may be undefined This is due to the FORE200E_NEXT_ENTRY macro, which essentially evaluates to: i = ++i % m Make it what's explicitly intended here which is: i = (i + 1) % m and the warning goes away.
