The documentation used "thinkpad-acpi" to refer to the directories in sysfs, while it should have been using "thinkpad_acpi". Thanks to Hugh Dickins for the error report. I wish I could just call the module and everything else by the proper name with the "-", instead of using these ugly translations to "_". Signed-off-by:

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.

The Averatec 2370 and some other Turion laptop BIOS seems to program the ENABLE_C1E MSR inconsistently between cores. This confuses the lapic use heuristics because when C1E is enabled anywhere it seems to affect the complete chip. Use a global flag instead of a per cpu flag to handle this. If any CPU has C1E enabled disabled lapic use. Thanks to Cal Peake for debugging. Cc: tglx@linutronix.de Signed-off-by:

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. Before, I was seeing times up to a minute or more to decompress a 1.3MB kernel on a very fast box. Signed-off-by:

Commit 19d36ccd "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!) AK: fix boot on x86-64 (sigh) AK: merged with other patches Signed-off-by:

Current code assumed that devices were directly connected to a Calgary bridge, as it tried to get the iommu table directly from the parent bus controller. When we have another bridge between the Calgary/CalIOC2 bridge and the device we should look upwards until we get to the top (Calgary/CalIOC2 bridge), where the iommu table resides. Signed-off-by:

There are some parts of include/asm-generic/pgtable.h that are relevant to the non-mmu architectures. To make it easier to include this from them I would like to ifdef the relevant parts. Without this there is a handful of functions that are referenced in here that are not defined on many non-mmu architectures. They could be defined out of course, as an alternative approach.

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? Signed-off-by:

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. [akpm@linux-foundation.org: export jpobe_return properly] Signed-off-by:

Patch c5c34d48 (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. (Thanks to Laurent for the above text, for finding, disgnosing and reporting the bug) - Use tty->flags bits for the flush status. - Wait for the flag to clear again before returning - Fix the doc error noted - Fix flush of empty queue leaving stale flushpending [akpm@linux-foundation.org: cleanup] Signed-off-by:

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!

For MPC8349E input to the SPI Baud Rate Generator is SYSCLK, but it's SYSCLK/2 for MPC8323E (SPI in QE). Fix this, and remove confusion by renaming the mpc83xx_spi->sysclk member as mpc83xx_spi->spibrg. Signed-off-by:
