After 6 years the ppc64 kernel still thinks its important to tell me my cache line size is 0x80 bytes. I think most people who care know that by now. The rest probably cant even understand the hex output. Since we might have misconfigured firmware or cpus that have a linesize that isnt 128 bytes, I still print it out for those cases. If people would prefer to remove it completely, lets do it. Also for lpar remove the htab_address printout since its not used. Anton ppc64 boot log usability expert Signed-off-by:

When checking out the new NO_HZ support in powerpc, I noticed we never slept for more than 2 seconds. It turns out SLAB has a 2 second per cpu timer that causes this. After switching to SLUB I see some nice 4 second sleeps which is the limit on this POWER6 box (the decrementer ticks at 512MHz): slept 4.19 sec slept 4.19 sec slept 4.19 sec slept 4.19 sec slept 3.96 sec slept 3.80 sec slept 2.99 sec Since SLUB is now the default and some powerpc defconfigs already enable it, lets enable SLUB across the board for consistency. While doing this I also noticed that the maple defconfig has SLAB debugging enabled which is sure to make your box nice and slow. Fix that too. Signed-off-by:

The devtree root is now searched for devices matching a built-in whitelist during boot, so these devices appear on the bus from the beginning. It is still possible to manually add/remove devices to/from the bus by using the probe/remove sysfs interface. Also, when a device driver registers itself, the devtree is matched against its matchlist. Signed-off-by:

Joachim Fenkes authored
Remove old code that will be replaced by rewritten and shorter functions in the next patch. Keep struct ibmebus_dev and struct ibmebus_driver for now, but replace ibmebus_{,un}register_driver() by dummy functions. This way, the kernel will still compile and run during the transition and git bisect will be happy. Signed-off-by: -
Joachim Fenkes authored
Extract generic of_device allocation code from of_platform_device_create() and move it into of_device.[ch], called of_device_alloc(). Also, there's now of_device_free() which puts the device node. This way, bus drivers that build on of_platform (like ibmebus will) can build upon this code instead of reinventing the wheel. Signed-off-by:

net: Fix new EMAC driver for NAPI changes This fixes the new EMAC driver for the NAPI updates. The previous patch by Roland Dreier (already applied) to do that doesn't actually work. This applies on top of it makes it work on my test Ebony machine. This patch depends on "net: Add __napi_sycnhronize() to sync with napi poll" posted previously. Signed-off-by:

Apparently poking the link status registers when autonegotiation is running on the PHY might botch the PHY link on 80003es2lan devices. While this is a very rare condition we can completely avoid it alltogether by just using the MAC link bits to provide the proper information to ethtool. Signed-off-by:

main change: * greatly improve per-NIC probe diagnostic output. Similar to other net drivers, print out MAC address, PHY info, and various hardware and software flags that may be relevant. other changes: * similar to other net drivers, only print the initial version message when we have found at least one board. * don't bother to print error message when pci_enable_device() fails, it will do so for us. * use dev_printk() rather than printk() in nv_probe(). This gives use a standardized output similar to the rest of the kernel, and eliminates the need to manually print out PCI bus id. * use DRV_NAME constant where appropriate * clean struct pci_driver indentation Signed-off-by: -

* We add ebitmap_for_each_positive_bit() which enables to walk on any positive bit on the given ebitmap, to improve its performance using common bit-operations defined in linux/bitops.h. In the previous version, this logic was implemented using a combination of ebitmap_for_each_bit() and ebitmap_node_get_bit(), but is was worse in performance aspect. This logic is most frequestly used to compute a new AVC entry, so this patch can improve SELinux performance when AVC misses are happen. * struct ebitmap_node is redefined as an array of "unsigned long", to get suitable for using find_next_bit() which is fasted than iteration of shift and logical operation, and to maximize memory usage allocated from general purpose slab. * Any ebitmap_for_each_bit() are repleced by the new implementation in ss/service.c and ss/mls.c. Some of related implementation are changed, however, there is no incompatibility with the previous version. * The width of any new line are less or equal than 80-chars. The following benchmark shows the effect of this patch, when we access many files which have different security context one after another. The number is more than /selinux/avc/cache_threshold, so any access always causes AVC misses. selinux-2.6 selinux-2.6-ebitmap AVG: 22.763 [s] 8.750 [s] STD: 0.265 0.019 ------------------------------------------ 1st: 22.558 [s] 8.786 [s] 2nd: 22.458 [s] 8.750 [s] 3rd: 22.478 [s] 8.754 [s] 4th: 22.724 [s] 8.745 [s] 5th: 22.918 [s] 8.748 [s] 6th: 22.905 [s] 8.764 [s] 7th: 23.238 [s] 8.726 [s] 8th: 22.822 [s] 8.729 [s] Signed-off-by:Stephen Smalley <sds@tycho.nsa.gov> Signed-off-by:
