2008-01-24spi: omap2_mcspi PIO RX fixKalle Valo1-3/+3
Before transmission of the last word in PIO RX_ONLY mode rx+tx mode is enabled: /* prevent last RX_ONLY read from triggering * more word i/o: switch to rx+tx */ if (c == 0 && tx == NULL) mcspi_write_cs_reg(spi, OMAP2_MCSPI_CHCONF0, l); But because c is decremented after the test, c will never be zero and rx+tx will not be enabled. This breaks RX_ONLY mode PIO transfers. Fix it by decrementing c in the beginning of the various I/O loops.

2008-01-24fix hugepages leak due to pagetable page sharingLarry Woodman1-0/+5
The shared page table code for hugetlb memory on x86 and x86_64 is causing a leak. When a user of hugepages exits using this code the system leaks some of the hugepages. ------------------------------------------------------- Part of /proc/meminfo just before database startup: HugePages_Total: 5500 HugePages_Free: 5500 HugePages_Rsvd: 0 Hugepagesize: 2048 kB Just before shutdown: HugePages_Total: 5500 HugePages_Free: 4475 HugePages_Rsvd: 0 Hugepagesize: 2048 kB After shutdown: HugePages_Total: 5500 HugePages_Free: 4988 HugePages_Rsvd: 0 Hugepagesize: 2048 kB ---------------------------------------------------------- The problem occurs durring a fork, in copy_hugetlb_page_range(). It locates the dst_pte using huge_pte_alloc(). Since huge_pte_alloc() calls huge_pmd_share() it will share the pmd page if can, yet the main loop in copy_hugetlb_page_range() does a get_page() on every hugepage. This is a violation of the shared hugepmd pagetable protocol and creates additional referenced to the hugepages causing a leak when the unmap of the VMA occurs. We can skip the entire replication of the ptes when the hugepage pagetables are shared. The attached patch skips copying the ptes and the get_page() calls if the hugetlbpage pagetable is shared.

2008-01-24lockdep: fix kernel crash on module unloadArjan van de Ven1-2/+5
Michael Wu noticed in his lkml post at http://marc.info/?l=linux-kernel&m=119396182726091&w=2 that certain wireless drivers ended up having their name in module memory, which would then crash the kernel on module unload. The patch he proposed was a bit clumsy in that it increased the size of a lockdep entry significantly; the patch below tries another approach, it checks, on module teardown, if the name of a class is in module space and then zaps the class. This is very similar to what we already do with keys that are in module space.

Linux does not want BIOS writers to invoke _OSI(Linux) - for in the field it causes more Windows incompatibility problems than it solves. So when it is seen in the BIOS for an Intel Customer Reference Board, Linux should ignore its effect by default, and should complain loudly.

Changeset 16b110c3fd760620b4a787db6ed512fe531ab1b5 (dmfe warning fix) bothed up the offsets read from the SROM so that it doesn't read the same datums it used to. The change made transformations like turning: "srom + 34" into "(__le32 *)srom + 34/4" which doesn't work because 4 does not divide evenly into 34 so we're using a different pointer offset than in the original code.

When we set the MFGPT timer tick, there is a chance that we'll immediately assert an event. If for some reason the IRQ routing for this clock has been setup for some other purpose, then we could end up firing an interrupt into the SMM handler or worse. This rearranges the timer tick init function to initalize the handler before we set up the MFGPT clock to make sure that even if we get an event, it will go to the handler. Furthermore, in the handler we need to make sure that we clear the event, even if the timer isn't running.

2008-01-22W1: w1_therm.c is flagging 0C etc as invalidDavid Fries1-1/+1
The extra rom[0] check is flagging valid temperatures as invalid when there is already a CRC data transmission check. w1_therm_read_bin() if (rom[8] == crc && rom[0]) verdict = 1; Requiring rom[0] to be non-zero will flag as invalid temperature conversions when the low byte is zero, specifically the temperatures 0C, 16C, 32C, 48C, -16C, -32C, and -48C. The CRC check is produced on the device for the previous 8 bytes and is required to ensure the data integrity in transmission. I don't see why the extra check for rom[0] being non-zero is in there. Evgeniy Polyakov didn't know either. Just for a check I unplugged the sensor, executed a temperature conversion, and read the results. The read was all ff's, which also failed the CRC, so it doesn't need to protect against a disconnected sensor. I have more extensive patches in the work, but these two trivial ones will do for today. I would like to hear from people who use the ds2490 USB to one wire dongle. 1 if you would be willing to test the patches as I currently only have the one sensor on a short parisite powered wire, 2 if there is any cheap sources for the ds2490.

2008-01-22hwmon: (it87) request only Environment Controller portsBjorn Helgaas1-9/+23
The IT8705F and related parts are Super I/O controllers that contain many separate devices. Some BIOSes describe IT8705F I/O port usage under a motherboard device (PNP0C02) with overlapping regions, e.g., 0x290-0x29f and 0x290-0x294. The it87 driver supports only the Environment Controller, which requires only two ISA ports, but it used to request an eight-port range. If that range exceeds a range reported by the BIOS, as 0x290-0x297 would, the request fails, and the it87 driver cannot claim the device. This patch makes the it87 driver request only the two ports used for the Environment Controller device.

2008-01-22Revert "x86: fix NMI watchdog & 'stopped time' problem"Thomas Gleixner2-17/+4
This reverts commit d4d25deca49ec2527a634557bf5a6cf449f85deb. It tried to fix long standing bugzilla entries, but the solution was reported to break other systems. The reporter of http://bugzilla.kernel.org/show_bug.cgi?id=9791 tracked it down to this commit and confirmed that reverting the patch restores the correct behaviour. It's too late in the release cycle to find a better solution than reverting the commit to avoid regressions. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: Ingo Molnar <mingo@elte.hu>
2008-01-21[SPARC64]: Fix section error in sparcspkrSam Ravnborg1-2/+2
With a sparc64 defconfig modified to set CONFIG_HOTPLUG=n the following error happened during link of vmlinux: local symbol 0: discarded in section `.devexit.text' from drivers/built-in.o local symbol 1: discarded in section `.devexit.text' from drivers/built-in.o (The error message above is from kbuild.git but it happens in mainline too) The error happens becase there is a reference from .text/.data to a function marked __devexit. With CONFIG_HOTPLUG=n all code marked __devexit are discarded and the linker complains. It was tracked down to sparcspkr.c which were missing __devexit_p() around the function pointers. Unfortunately modpost did not catch this since modpost do not warn about references from .data to .devexit from variables named *_driver.

2008-01-21Fix filesystem capability supportAndrew G. Morgan1-3/+10
In linux-2.6.24-rc1, security/commoncap.c:cap_inh_is_capped() was introduced. It has the exact reverse of its intended behavior. This led to an unintended privilege esculation involving a process' inheritable capability set. To be exposed to this bug, you need to have Filesystem Capabilities enabled and in use. That is: - CONFIG_SECURITY_FILE_CAPABILITIES must be defined for the buggy code to be compiled in. - You also need to have files on your system marked with fI bits raised. Signed-off-by: Andrew G.

2008-01-21s3c2410_fb: fix line length calculationStefan Schmidt1-1/+1
Fix line length calculation. var->width is the size of the display in mm. We like to use the pixel size. Without this fix, dynamic (fbset) based resolution and depths changes with s3c2410_fb don't work at all.
