2007-08-11i386: Fix double fault handlerChuck Ebbert
The new percpu code has apparently broken the doublefault handler when CONFIG_DEBUG_SPINLOCK is set. Doublefault is handled by a hardware task, making the check SPIN_BUG_ON(lock->owner == current, lock, "recursion"); fault because it uses the FS register to access the percpu data for current, and that register is zero in the new TSS. (The trace I saw was on 2.6.20 where it was GS, but it looks like this will still happen with FS on 2.6.22.) Initializing FS in the doublefault_tss should fix it.

VT is very picky about when it can enter execution. Get all segments setup and get LDT and TR into valid state to allow VT execution under VMware and KVM (untested). This makes the boot decompression run under VT, which makes it several orders of magnitude faster on 64-bit Intel hardware.

2007-08-11i386: Make patching more robust, fix paravirt issueAndi Kleen
Commit 19d36ccdc34f5ed444f8a6af0cbfdb6790eb1177 "x86: Fix alternatives and kprobes to remap write-protected kernel text" uses code which is being patched for patching. In particular, paravirt_ops does patching in two stages: first it calls paravirt_ops.patch, then it fills any remaining instructions with nop_out(). nop_out calls text_poke() which calls lookup_address() which calls pgd_val() (aka paravirt_ops.pgd_val): that call site is one of the places we patch. If we always do patching as one single call to text_poke(), we only need make sure we're not patching the memcpy in text_poke itself. This means the prototype to paravirt_ops.patch needs to change, to marshal the new code into a buffer rather than patching in place as it does now. It also means all patching goes through text_poke(), which is known to be safe (apply_alternatives is also changed to make a single patch). AK: fix compilation on x86-64 (bad rusty!)

2007-08-11finish i386 and x86-64 sysdata conversionMuli Ben-Yehuda
This patch finishes the i386 and x86-64 ->sysdata conversion and hopefully also fixes Riku's and Andy's observed bugs. It is based on Yinghai Lu's and Andy Whitcroft's patches (thanks!) with some changes: - introduce pci_scan_bus_with_sysdata() and use it instead of pci_scan_bus() where appropriate. pci_scan_bus_with_sysdata() will allocate the sysdata structure and then call pci_scan_bus(). - always allocate pci_sysdata dynamically. The whole point of this sysdata work is to make it easy to do root-bus specific things (e.g., support PCI domains and IOMMU's). I dislike using a default struct pci_sysdata in some places and a dynamically allocated pci_sysdata elsewhere - the potential for someone indavertantly changing the default structure is too high. - this patch only makes the minimal changes necessary, i.e., the NUMA node is always initialized to -1. Patches to do the right thing with regards to the NUMA node can build on top of this (either add a 'node' parameter to pci_scan_bus_with_sysdata() or just update the node when it becomes known). The patch was compile tested with various configurations (e.g., NUMAQ, VISWS) and run-time tested on i386 and x86-64. Unfortunately none of my machines exhibited the bugs so caveat emptor. Andy, could you please see if this fixes the NUMA issues you've seen? Riku, does this fix "pci=noacpi" on your laptop?

2007-08-11fix compilation with gcc 4.2Peter Chubb
gcc-4.2 is a lot more picky about its symbol handling. EXPORT_SYMBOL no longer works on symbols that are undefined or defined with static scope. For example, with CONFIG_PROFILE off, I see: kernel/profile.c:206: error: __ksymtab_profile_event_unregister causes a section type conflict kernel/profile.c:205: error: __ksymtab_profile_event_register causes a section type conflict This patch moves the EXPORTs inside the #ifdef CONFIG_PROFILE, so we only try to export symbols that are defined. Also, in kernel/kprobes.c there's an EXPORT_SYMBOL_GPL() for jprobes_return, which if CONFIG_JPROBES is undefined is a static inline and gives the same error. And in drivers/acpi/resources/rsxface.c, there's an ACPI_EXPORT_SYMBOPL() for a static symbol. If it's static, it's not accessible from outside the compilation unit, so should bot be exported. These three changes allow building a zx1_defconfig kernel with gcc 4.2 on IA64.

2007-08-11fix serial buffer memory leakAlan Cox
Patch c5c34d4862e18ef07c1276d233507f540fb5a532 (tty: flush flip buffer on ldisc input queue flush) introduces a race condition which can lead to memory leaks. The problem can be triggered when tcflush() is called when data are being pushed to the line discipline driver by flush_to_ldisc(). flush_to_ldisc() releases tty->buf.lock when calling the line discipline receive_buf function. At that poing tty_buffer_flush() kicks in and sets both tty->buf.head and tty->buf.tail to NULL. When flush_to_ldisc() finishes, it restores tty->buf.head but doesn't touch tty->buf.tail. This corrups the buffer queue, and the next call to tty_buffer_request_room() will allocate a new buffer and overwrite tty->buf.head. The previous buffer is then lost forever without being released.

2007-08-11spi_mpc83xx: fix prescale modulus calculationAnton Vorontsov
Long ago I've noticed (but didn't pay much attention) that spi_mpc83xx using PM calculations that differs from what specs describe. I.e. u8 pm = mpc83xx_spi->spibrg / (spi->max_speed_hz * 4); While specs says: "The SPI baud rate generator clock source (either system clock or system clock divided by 16, depending on DIV16 bit) is divided by 4 * ([PM] + 1), a range from 4 to 64.". Thus " - 1" is missing in the spi_mpc83xx's formula. Why nobody noticed that bug? Probably because sysclk usually less then user expects, e.g. you expect 200 MHz, but real clock is 198 MHz, and integer rounding helps when this formula is used. Suppose it's SPI in QE, SYSCLK at 198 MHz, thus SPIBRG at 99MHz, 25 MHz requested. PM = (99MHz / ( 25 MHz * 4 )), PM == 0, output SPICLK will be 24.75 MHz At lower frequencies this bug is more noticeable, though. And this bug shows itself in all its beauty if SYSCLK is equal or a bit more than you expect (200 MHz SYSCLK, 100 MHz SPIBRG): PM = (100MHz / ( 25 MHz * 4 )), PM == 1, output SPICLK will be 12.625 MHz!

2007-08-11eCryptfs: fix error handling in ecryptfs_initRyusuke Konishi
ecryptfs_init() exits without doing any cleanup jobs if ecryptfs_init_messaging() fails. In that case, eCryptfs leaves sysfs entries, leaks memory, and causes an invalid page fault. This patch fixes the problem.

2007-08-11eCryptfs: fix lookup error for special filesRyusuke Konishi
When ecryptfs_lookup() is called against special files, eCryptfs generates the following errors because it tries to treat them like regular eCryptfs files. Error opening lower file for lower_dentry [0xffff810233a6f150], lower_mnt [0xffff810235bb4c80], and flags [0x8000] Error opening lower_file to read header region Error attempting to read the [user.ecryptfs] xattr from the lower file; return value = [-95] Valid metadata not found in header region or xattr region; treating file as unencrypted For instance, the problem can be reproduced by the steps below. # mkdir /root/crypt /mnt/crypt # mount -t ecryptfs /root/crypt /mnt/crypt # mknod /mnt/crypt/c0 c 0 0 # umount /mnt/crypt # mount -t ecryptfs /root/crypt /mnt/crypt # ls -l /mnt/crypt This patch fixes it by adding a check similar to directories and symlinks.

2007-08-11matroxfb: rectify jitter (G450/G550)Paul A. Clarke
This builds upon my previous attempts to resolve some jitter problems seen with the Matrox G450 and G550 -based cards, including odd disparities observed between x86 and Power -based machines in a somewhat less hackish way (removing the hacked ifdefs). Apparently, preference should be given to use the DVI PLL when frequencies permit, the Standard PLL otherwise. The max pixel clock for the panellink interface is extracted from the PInS information on the card and used as a limit to determine which PLL to use. Signed-off-by: Paul A.

2007-08-11pvr2fb: Consolidated cleanup of pvr2fb.cAdrian McMenamin
- better handling of the pvr2 registers based on more up to date information. Testing shows that it seems to work pretty well at 16bpp, 24bpp and 32bpp - including proper rendering of the boot logo at all levels (previously this was a bit broken even at 16bpp) and giving white against black text. Really detailed testing (eg with X11) requires support for the maple bus - which isn't (currently - next project assuming this is okay) available, but I have no reason to think this is broken.
