* [PATCH] powerpc: Always panic if lmb_alloc() failsMichael Ellerman2006-02-071-0/+2
| | | | | | | | | | | | | | | | Currently most callers of lmb_alloc() don't check if it worked or not, if it ever does weird bad things will probably happen. The few callers who do check just panic or BUG_ON. So make lmb_alloc() panic internally, to catch bugs at the source. The few callers who did check the result no longer need to. The only caller that did anything interesting with the return result was careful_allocation(). For it we create __lmb_alloc_base() which _doesn't_ panic automatically, a little messy, but passable.

| | | | | | | | | | | | | | | | | | | | platfom bus. This patch only deals with the serial port definitions as there is no support for any other xilinx IP cores in the kernel tree at the moment. Board specific configuration moved out of virtex.[ch] and into the xparameters.h wrapper. This also prepares for the transition to the flattened device tree model. When the bootloader provides a device tree generated from an xparameters.h files, the kernel will no longer need xparameters/*. The platform bus will get populated with data from the device tree, and the device drivers will be automatically connected to the devices. Only the bootloader (or ppcboot) will need xparameters directly. Signed-off-by: Grant C. Likely <grant.likely@secretlab.ca> Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | xparameters should not be needed by anything but virtex platform code. Move it from include/asm-ppc/ to platforms/4xx/xparameters/ This is preparing for work to remove xparameters from the dependancy tree for most c files. xparam changes should not cause a recompile of the world. Instead, drivers should get device info from the platform bus (populated by the boot code) Signed-off-by: Grant C. Likely <grant.likely@secretlab.ca> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] powerpc: Don't overwrite flat device tree with kdump kernelMichael Ellerman2006-02-071-0/+2
| | | | | | | | | | | | | | It's possible for prom_init to allocate the flat device tree inside the kdump crash kernel region. If this happens, when we load the kdump kernel we overwrite the flattened device tree, which is bad. We could make prom_init try and avoid allocating inside the crash kernel region, but then we run into issues if the crash kernel region uses all the space inside the RMO. The easiest solution is to move the flat device tree once we're running in the kernel. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>

* | [PATCH] jbd: fix transaction batchingAndrew Morton2006-02-051-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ben points out that: When writing files out using O_SYNC, jbd's 1 jiffy delay results in a significant drop in throughput as the disk sits idle. The patch below results in a 4-5x performance improvement (from 6.5MB/s to ~24-30MB/s on my IDE test box) when writing out files using O_SYNC. So optimise the batching code by omitting it entirely if the process which is doing a sync write is the same as the one which did the most recent sync write. If that's true, we're unlikely to get any other processes joining the transaction. (Has been in -mm for ages - it took me a long time to get on to performance testing it) Numbers, on write-cache-disabled IDE: /usr/bin/time -p synctest -n 10 -uf -t 1 -p 1 dir-name Unpatched: 40 seconds Patched: 35 seconds Batching disabled: 35 seconds This is the problematic single-process-doing-fsync case. With multiple fsyncing processes the numbers are AFACIT unaltered by the patch. Aside: performance testing and instrumentation shows that the transaction batching almost doesn't help (testing with synctest -n 1 -uf -t 100 -p 10 dir-name on non-writeback-caching IDE). This is because by the time one process is running a synchronous commit, a bunch of other processes already have a transaction handle open, so they're all going to batch into the same transaction anyway. The batching seems to offer maybe 5-10% speedup with this workload, but I'm pretty sure it was more important than that when it was first developed 4-odd years ago... Cc: "Stephen C.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The pktcdvd driver uses a compile time macro constant to define the maximum supported packet length. I changed this from 32 sectors to 128 sectors because that allows over 100 MB of additional usable space on a 700 MB cdrw, and increases throughput. Note that you need a modified cdrwtool program that can format a CDRW disc with larger packets to benefit from this change.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pktcdvd driver was using an 8 bit field to store the packet length obtained from the disc track info. This causes it to overflow packet length values of 128KB or more. I changed the field to 32 bits to fix this. The pktcdvd driver defaulted to its maximum allowed packet length when it detected a 0 in the track info field. I changed this to fail the operation and refuse to access the media. This seems more sane than attempting to access it with a value that almost certainly will not work.

* [PATCH] x86_64: Calibrate APIC timer using PM timerAndi Kleen2006-02-041-0/+1
| | | | | | | | | | | | | | | | | | | | | On some broken motherboards (at least one NForce3 based AMD64 laptop) the PIT timer runs at a incorrect frequency. This patch adds a new option "apicpmtimer" that allows to use the APIC timer and calibrate it using the PMTimer. It requires the earlier patch that allows to run the main timer from the APIC. Specifying apicpmtimer implies apicmaintimer. The option defaults to off for now. I tested it on a few systems and the resulting APIC timer frequencies were usually a bit off, but always <1%, which should be tolerable. TBD figure out heuristic to enable this automatically on the affected systems TBD perhaps do it on all NForce3s or using DMI?

* [PATCH] x86_64: Fix the node cpumask of a cpu going downRavikiran G Thirumalai2006-02-041-0/+7
| | | | | | | | | | | | | | | | | | | Currently, x86_64 and ia64 arches do not clear the corresponding bits in the node's cpumask when a cpu goes down or cpu bring up is cancelled. This is buggy since there are pieces of common code where the cpumask is checked in the cpu down code path to decide on things (like in the slab down path). PPC does the right thing, but x86_64 and ia64 don't (This was the reason Sonny hit upon a slab bug during cpu offline on ppc and could not reproduce on other arches). This patch fixes it for x86_64. I won't attempt ia64 as I cannot test it. Credit for spotting this should go to Alok.

| | | | | | | | | | | | | | | | | | | | | | Another piece from the no-idle-tick patch. This can be enabled with the "apicmaintimer" option. This is mainly useful when the PIT/HPET interrupt is unreliable. Note there are some systems that are known to stop the APIC timer in C3. For those it will never work, but this case should be automatically detected. It also only works with PM timer right now. When HPET is used the way the main timer handler computes the delay doesn't work. It should be a bit more efficient because there is one less regular interrupt to process on the boot processor.

* | | | | [PATCH] ia64: drop arch-specific IDE MAX_HWIFS definitionBjorn Helgaas2006-02-031-8/+0

This reduces the default from 10 to 4, but I don't think that's a problem.

* | | | | [PATCH] new tty buffering locking fixPaul Fulghum2006-02-033-1/+13

New locking uses a new tty buffering specific lock enforced centrally in the tty buffering code. Two drivers (esp and cyclades) are updated to use the tty buffering functions instead of accessing tty buffering internals directly. This is required for the new locking to work. Minor checks for NULL buffers added to tty_prepare_flip_string/tty_prepare_flip_string_flags Signed-off-by: Paul Fulghum <paulkf@microgate.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
