Merge reason: Suresh Siddha (1): x86, pat: don't use rb-tree based lookup in reserve_memtype() ... requires previous x86/pat commits already pushed to Linus. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
2009-09-17x86, pat: don't use rb-tree based lookup in reserve_memtype()Suresh Siddha1-10/+2
Recent enhancement of rb-tree based lookup exposed a bug with the lookup mechanism in the reserve_memtype() which ensures that there are no conflicting memtype requests for the memory range. memtype_rb_search() returns an entry which has a start address <= new start address. And from here we traverse the linear linked list to check if there any conflicts with the existing mappings. As the rbtree is based on the start address of the memory range, it is quite possible that we have several overlapped mappings whose start address is much less than new requested start but the end is >= new requested end. This results in conflicting memtype mappings. Same bug exists with the old code which uses cached_entry from where we traverse the linear linked list. But the new rb-tree code exposes this bug fairly easily. For now, don't use the memtype_rb_search() and always start the search from the head of linear linked list in reserve_memtype(). Linear linked list for most of the systems grow's to few 10's of entries(as we track memory type of RAM pages using struct page). So we should be ok for now. We still retain the rbtree and use it to speed up free_memtype() which doesn't have the same bug(as we know what exactly we are searching for in free_memtype). Also use list_for_each_entry_from() in free_memtype() so that we start the search from rb-tree lookup result.

2009-09-17pata_amd: do not filter out valid modes in nv_mode_filterRobert Hancock1-0/+3
On a Compaq Presario V3000 laptop (NVIDIA MCP51 chipset), pata_amd selects PIO0 mode for the PATA DVD-RAM drive instead of MWDMA2 which it supports: ata4.00: ATAPI: HL-DT-ST DVDRAM GSA-4084N, KQ09, max MWDMA2 ata4: nv_mode_filter: 0x39f&0x7001->0x1, BIOS=0x0 (0x0) ACPI=0x7001 (60:600:0x11) ata4.00: configured for PIO0 For some reason, the BIOS-set UDMA configuration returns 0 and the ACPI _GTM reports that UDMA2 and PIO0 are enabled. This causes nv_mode_filter to end up allowing only PIO0 and UDMA0-2. Since the drive doesn't support UDMA we end up using PIO0. Since the controllers should always support PIO4, MWDMA2 and UDMA2 regardless of what cable type is used, let's make sure we don't filter out these modes regardless of what wacky settings the BIOS is using.

2009-09-17sata_promise: update reset codeMikael Pettersson1-1/+120
sata_promise's reset code has deviated quite a bit from the Promise reference driver's, and it has been observed to fail to recover from errors in some cases. This patch thus updates the reset code to more closely match the reference driver: - soft reset (pdc_reset_port): * wait for ATA engine to not be in packet command mode (2nd gen only) * write reset bit in PDC_CTLSTAT before the first read in the loop * for 2nd gen SATA follow up with FPDMA reset and clearing error status registers - hard reset (pdc_sata_hardreset): * wait for ATA engine to not be in packet command mode (2nd gen only) * reset ATA engine via the PCI control register * Tejun's change to use non-waiting hardreset + follow-up SRST I'm not changing the hotplug mask bits since they are taken care of by sata_promise's ->freeze() and ->thaw() operations. And I'm not writing the PMP port # because that's always zero (for now). Tested here on various controllers. In particular, one disk which used to timeout and fail to recover from certain hdparm and smartmonctl commands now works nicely.

2009-09-17sata_promise: disable hotplug on 1st gen chipsMikael Pettersson1-17/+17
1st generation Promise SATA chips are prone to generating spurious hotplug events which can disrupt normal operation. This has been observed on 20376 and 20378 chips. This patch thus disables hotplug support on 1st gen chips while leaving it enabled for 2nd gen chips. The pdc_sata_hotplug_offset() function becomes redundant so it is removed. Tested on 1st gen 20376 and 20378 mainboard chips and on a 2nd gen SATA300 PCI card.

2009-09-17libata: fix spurious WARN_ON_ONCE() on port freezeTejun Heo1-2/+2
Commit 54c38444fad6a99b4b19512f8f0055d69115e69e makes libata abort qcs after the port is frozen. This is necessary to guarantee that TF registers are accessed after the DMA engine is shutdown after an error. However, this triggers WARN_ON_ONCE() check in ata_qc_complete() spuriously. Move WARN_ON_ONCE() downwards such that failing commands while frozen doesn't trigger it.

2009-09-17ahci: restore pci_intx() handlingTejun Heo1-2/+2
Commit a5bfc4714b3f01365aef89a92673f2ceb1ccf246 dropped explicit pci_intx() manipulation from ahci because it seemed unnecessary and ahci doesn't seem to be the right place to be tweaking it if it were. This was largely okay but there are exceptions. There was one on an embedded platform which was fixed via firmware and now bko#14124 reports it on a HP DL320. http://bugzilla.kernel.org/show_bug.cgi?id=14124 I still think this isn't something libata drivers should be caring about (the only ones which are calling pci_intx() explicitly are libata ones and one other driver) but for now reverting the change seems to be the right thing to do.

2009-09-17tracing: switch function prints from %pf to %psSteven Rostedt3-7/+7
For direct function pointers (like what mcount provides) PowerPC64 requires the use of %ps, otherwise nothing is printed. This patch converts all prints of functions retrieved through mcount to use the %ps format from the %pf. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
2009-09-17vsprintf: add %ps that is the same as %pS but is like %pfSteven Rostedt1-2/+4
On PowerPC64 function pointers do not point directly at the functions, but instead point to pointers to the functions. The output of %pF expects to point to a pointer to the function, whereas %pS will show the function itself. mcount returns the direct pointer to the function and not the pointer to the pointer. Thus %pS must be used to show this. The function tracer requires printing of the functions without offsets and uses the %pf instead. %pF produces run_local_timers+0x4/0x1f %pf produces just run_local_timers For PowerPC64, we need to use the direct pointer, and we only have %pS which will produce .run_local_timers+0x4/0x1f This patch creates a %ps that matches the %pf as %pS matches %pF.

2009-09-17MIPS: Allow kernel use of LL/SC to be separate from the presence of LL/SC.David Daney6-47/+50
On some CPUs, it is more efficient to disable and enable interrupts in the kernel rather than use ll/sc for atomic operations. But if we were to set cpu_has_llsc to false, we would break the userspace futex interface (in asm/futex.h). We separate the two concepts, with a new predicate kernel_uses_llsc, that lets us disable the kernel's use of ll/sc while still allowing the futex code to use it. Also there were a couple of cases in bitops.h where we were using ll/sc unconditionally even if cpu_has_llsc were false.

We move the dynamic resource calculation here since the driver should not be aware of the AR7 SoC version it is running on.

2009-09-17MIPS: Loongson: Add GCC 4.4 support for Loongson2EWu Zhangjin3-9/+17
Because only gcc >=4.4 have loongson-specific support, we need to choose the suitable -march argument for gcc <= 4.3 and gcc >= 4.4, and here, we use -march=loongson2e for loongson2e. Thanks goes to Arnaud Patard <apatard@mandriva.com> for suggestion of using cc-options(Documentation/kbuild/makefiles.txt). and thanks Zhang Le for introducing the new CPU_LOONGSON2E kernel option. NOTE: -mtune option is not need if -march and -mtune use the same value.

2009-09-17MIPS: Loongson: Add a machtype kernel command line argumentWu Zhangjin6-4/+53
The difference between some loongson-based machines is very small, so, if there is no necessary to add new kernel config options to cope with this difference, it will be better to share the same kernel image file between them, benefit from this, the linux distribution developers only have a need to compile the kernel one time. This machtype kernel command line argument will be used later to share the same kernel image file between two different machines(menglong & yeeloong) made by lemote. Thanks very much to Zhang Le for cleaning up the machtype implementation. Signed-off-by: Wu Zhangjin <wuzhangjin@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: Loongson: Split common loongson source code outWu Zhangjin24-133/+351
To share common loongson source code between all of the loongson-based machines. there is a need to split it out of the fuloong-2e/ directory. at the same time, other according tuning is needed. the machine-specific parts are defined as macros in relative header file, pci.h, mem.h, machine.h.
