* [PATCH] Pass struct dev pointer to dma_cache_sync()Ralf Baechle2006-12-07
| | | | | | | | | | | | | | | | | Pass struct dev pointer to dma_cache_sync() dma_cache_sync() is ill-designed in that it does not have a struct device pointer argument which makes proper support for systems that consist of a mix of coherent and non-coherent DMA devices hard. Change dma_cache_sync to take a struct device pointer as first argument and fix all its callers to pass it.

* [PATCH] fs: reorder some 'struct inode' fields to speedup i_size manipulationsEric Dumazet2006-12-07
| | | | | | | | | | | | | | | | | | | On 32bits SMP platforms, 64bits i_size is protected by a seqcount (i_size_seqcount). When i_size is read or written, i_size_seqcount is read/written as well, so it make sense to group these two fields together in the same cache line. This patch moves i_size_seqcount next to i_size, and also moves i_version to let offsetof(struct inode, i_size) being 0x40 instead of 0x3c (for 32bits platforms). For 64 bits platforms, i_size_seqcount doesnt exist, and the move of a 'long i_version' should not introduce a new hole because of padding.

* [PATCH] net: don't insert socket dentries into dentry_hashtableEric Dumazet2006-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently insert socket dentries into the global dentry hashtable. This is suboptimal because there is currently no way these entries can be used for a lookup(). (/proc/xxx/fd/xxx uses a different mechanism). Inserting them in dentry hashtable slows dcache lookups. To let __dpath() still work correctly (ie not adding a " (deleted)") after dentry name, we do : - Right after d_alloc(), pretend they are hashed by clearing the DCACHE_UNHASHED bit. - Call d_instantiate() instead of d_add() : dentry is not inserted in hash table. __dpath() & friends work as intended during dentry lifetime. - At dismantle time, once dput() must clear the dentry, setting again DCACHE_UNHASHED bit inside the custom d_delete() function provided by socket code, so that dput() can just kill_it.

* [PATCH] dcache: avoid RCU for never-hashed dentriesEric Dumazet2006-12-07
| | | | | | | | | | | | | | | | | | | | | | Some dentries don't need to be globally visible in dentry hashtable. (pipes & sockets) Such dentries dont need to wait for a RCU grace period at delete time.

* [PATCH] rcu: add a prefetch() in rcu_do_batch()Eric Dumazet2006-12-07
| | | | | | | | | | | | | | | | | | | | | | On some workloads, (for example when lot of close() syscalls are done), RCU qlen can be quite large, and RCU heads are no longer in cpu cache when rcu_do_batch() is called. This patch adds a prefetch() in rcu_do_batch() to give CPU a hint to bring back cache lines containing 'struct rcu_head's. Most list manipulations macros include prefetch(), but not open coded ones (at least with current C compilers :) ) I got a nice speedup on a trivial benchmark (3.48 us per iteration instead of 3.95 us on a 1.6 GHz Pentium-M) while (1) { pipe(p); close(fd[0]); close(fd[1]);} Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Cc: "Paul E.

* [PATCH] add rtc-omap driverDavid Brownell2006-12-07
| | | | | | | | | | | | | | This creates a new RTC-framework driver for the RTC/calendar module found in various OMAP1 chips. (OMAP2 and OMAP3 use external RTCs, like those in TI's multifunction PM companion chips.) It's been in the Linux-OMAP tree for several months now, and other trees before that, so it's quite stable. The most notable issue is that the OMAP IRQ code doesn't yet support the RTC IRQ as a wakeup event. Once that's fixed, a patch will be needed.

* [PATCH] kprobes: enable booster on the preemptible kernelMasami Hiramatsu2006-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we are unregistering a kprobe-booster, we can't release its instruction buffer immediately on the preemptive kernel, because some processes might be preempted on the buffer. The freeze_processes() and thaw_processes() functions can clean most of processes up from the buffer. There are still some non-frozen threads who have the PF_NOFREEZE flag. If those threads are sleeping (not preempted) at the known place outside the buffer, we can ensure safety of freeing. However, the processing of this check routine takes a long time. So, this patch introduces the garbage collection mechanism of insn_slot. It also introduces the "dirty" flag to free_insn_slot because of efficiency. The "clean" instruction slots (dirty flag is cleared) are released immediately. But the "dirty" slots which are used by boosted kprobes, are marked as garbages. collect_garbage_slots() will be invoked to release "dirty" slots if there are more than INSNS_PER_PAGE garbage slots or if there are no unused slots.

* [PATCH] elf: Always define elf_addr_t in linux/elf.hMagnus Damm2006-12-07
| | | | | | | | | | | | | Define elf_addr_t in linux/elf.h. The size of the type is determined using ELF_CLASS. This allows us to remove the defines that today are spread all over .c and .h files.

* [PATCH] Fix the size limit of compat space msgsizesuzuki2006-12-07
| | | | | | | | | | | | | | | | | | | | | | | Currently we allocate 64k space on the user stack and use it the msgbuf for sys_{msgrcv,msgsnd} for compat and the results are later copied in user [ by copy_in_user]. This patch introduces helper routines for sys_{msgrcv,msgsnd} as below: do_msgsnd() : Accepts the mtype and user space ptr to the buffer along with the msqid and msgflg. do_msgrcv() : Accepts a kernel space ptr to mtype and a userspace ptr to the buffer. The mtype has to be copied back the user space msgbuf by the caller. These changes avoid the need to allocate the msgsize on the userspace ( thus removing the size limt ) and the overhead of an extra copy_in_user().

* [PATCH] ktime: Fix signed / unsigned mismatch in ktime_to_nsThomas Gleixner2006-12-07
| | | | | | | | | | | | The 32 bit implementation of ktime_to_ns returns unsigned value, while the 64 bit version correctly returns an signed value. There is no current user affected by this, but it has to be fixed, as ktime values can be negative.
