* Fix spurious syscall tracing after PTRACE_DETACH + PTRACE_ATTACHRoland McGrath2007-09-10
| | | | | | | | | | | | | | | | | | | | | | When PTRACE_SYSCALL was used and then PTRACE_DETACH is used, the TIF_SYSCALL_TRACE flag is left set on the formerly-traced task. This means that when a new tracer comes along and does PTRACE_ATTACH, it's possible he gets a syscall tracing stop even though he's never used PTRACE_SYSCALL. This happens if the task was in the middle of a system call when the second PTRACE_ATTACH was done. The symptom is an unexpected SIGTRAP when the tracer thinks that only SIGSTOP should have been provoked by his ptrace calls so far. A few machines already fixed this in ptrace_disable (i386, ia64, m68k). But all other machines do not, and still have this bug. On x86_64, this constitutes a regression in IA32 compatibility support. Since all machines now use TIF_SYSCALL_TRACE for this, I put the clearing of TIF_SYSCALL_TRACE in the generic ptrace_detach code rather than adding it to every other machine's ptrace_disable.

| | | | | | | | | | | | Don't include RODATA into text segment as it includes the kallsyms data and can cause spurious link failures (layout differences can change the number of symbols in kallsyms, i.e. when a symbol is equal to _etext it's not included).

* Remove fs.h from mm.hAlexey Dobriyan2007-07-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove fs.h from mm.h. For this, 1) Uninline vma_wants_writenotify(). It's pretty huge anyway. 2) Add back fs.h or less bloated headers (err.h) to files that need it. As result, on x86_64 allyesconfig, fs.h dependencies cut down from 3929 files rebuilt down to 3444 (-12.3%).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a crash caused by requests placed in the queue with the completed flag already set. This lead to some ADB_SYNC requests returning early and their request structs being popped off the stack while still queued. Stack corruption ensued or an invalid request callback pointer was invoked or both. Eliminate macii_retransmit() and its buggy implementation of macii_write(). Have macii_queue_poll() fully initialise the request queues. Fix a bug in macii_queue_poll() where the last_req pointer was not being set. This caused some requests to leave the queue before being completed (and would also corrupt the stack under certain conditions). Fix a race in macii_start that could set the state machine to "reading" while current_req was null. No longer send poll commands with the ADBREQ_REPLY flag -- doing that caused the replies to be stored in the request buffer where they were forgotten about. Don't autopoll by continuously sending new Talk commands. Get the controller to do that for us. This reduces the ADB interrupt rate on an idle bus to about 5 per second. Only autopoll the devices that were probed. Explicitly clear the interrupt flag when polling. Use disable_irq rather than local_irq_save when polling. Remove excess local_irq_save/restore pairs. Improve bus timeout and service request detection. Remove unused code (last_reply, adb_dir etc) and unneeded code (prefix_len, first_byte etc). Change TIP and TACK to their correct names on this ADB controller (ST_EVEN and ST_ODD). Add some commentry. Add a generous quantity of sanity checks (BUG_ONs). Let m68k macs use the adb_sync boot param too.

* m68k: Mac nubus IRQ fixes (plan E)Finn Thain2007-05-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Macs lack a slot interrupt enable register. So the existing code makes disabled and unregistered slot IRQ lines outputs set high. This seems to work on quadras, but does not work on genuine VIAs (perhaps the card still succeeds in pulling the line low, or perhaps because this increases the settle time on the port A input, meaning that the CA1 IRQ could fire before the slot line reads active). Because of this, the nubus_active flags were used to mask IRQs, which is actually worse than the problem it tries to solve. Any interrupt masked by nubus_active will remain asserted and prevent further transitions on CA1. And so the nubus gets wedged regardless of hardware (emulated VIA ASIC, real VIA chip or RBV). The best solution to this hardware limitation of genuine VIAs is to disable the umbrella SLOTS IRQ when disabling a slot on those machines. Unfortunately, this means all slot IRQs get disabled when any slot IRQ is disabled. But it is only a problem when there's more than 1 device using nubus interrupts. Another potential problem for genuine VIAs is an unregistered nubus IRQ. Eventually it will be possible to enable the CA1 interrupt by installing its handler only _after_ all nubus drivers have loaded but _before_ the kernel needs them, at which time this last problem can be fixed. For now it can be worked around: - disable MacOS extensions - don't boot MacOS (use the Emile bootloader instead) - get the bootloaders to disable ROM drivers (Penguin does this for video cards already, don't know about Emile) - physically remove unsupported cards Signed-off-by: Finn Thain <fthain@telegraphics.com.au> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| | | | | | | | | | | | | | | | Make sure that there are no slot IRQs asserted before leaving the nubus handler.

* [PATCH] mark struct file_operations const 2Arjan van de Ven2007-02-12
| | | | | | | | | | | | Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

* [PATCH] Set CONFIG_ZONE_DMA for arches with GENERIC_ISA_DMAChristoph Lameter2007-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | As Andi pointed out: CONFIG_GENERIC_ISA_DMA only disables the ISA DMA channel management. Other functionality may still expect GFP_DMA to provide memory below 16M. So we need to make sure that CONFIG_ZONE_DMA is set independent of CONFIG_GENERIC_ISA_DMA. Undo the modifications to mm/Kconfig where we made ZONE_DMA dependent on GENERIC_ISA_DMA and set theses explicitly in each arches Kconfig. Reviews must occur for each arch in order to determine if ZONE_DMA can be switched off. It can only be switched off if we know that all devices supported by a platform are capable of performing DMA transfers to all of memory (Some arches already support this: uml, avr32, sh sh64, parisc and IA64/Altix). In order to switch ZONE_DMA off conditionally, one would have to establish a scheme by which one can assure that no drivers are enabled that are only capable of doing I/O to a part of memory, or one needs to provide an alternate means of performing an allocation from a specific range of memory (like provided by alloc_pages_range()) and insure that all drivers use that call. In that case the arches alloc_dma_coherent() may need to be modified to call alloc_pages_range() instead of relying on GFP_DMA.
