When I removed the powermac support from arch/ppc/kernel/pci.c, I overlooked the fact that that file is used in 32-bit ARCH=powerpc builds. To prevent problems in future, restore the original version of that file as arch/powerpc/kernel/pci_32.c, and use that. Signed-off-by:Paul Mackerras <paulus@samba.org>

This makes ARCH=powerpc the default on 32-bit powerpc machines, where uname -m returns ppc, as well as on 64-bit powerpc machines. Most people who would be likely to build their own kernels on 32-bit powerpc machines would be using powermacs or CHRP machines, both of which are supported with ARCH=powerpc now. Embedded ppc developers whose ports haven't been moved over to arch/powerpc yet will have to explicitly set ARCH=ppc now. Signed-off-by: -

This makes it possible to build kernels for PReP and/or CHRP with ARCH=ppc by removing the (non-building) powermac support. It's now also possible to select PReP and CHRP independently. Powermac users should now build with ARCH=powerpc instead of ARCH=ppc. (This does mean that it is no longer possible to build a 32-bit kernel for a G5.) Signed-off-by: -

Some versions of gcc generate incorrect code for the inet_check_attr() function, apparently due to a totally bogus index -> pointer comparison transformation. At least "gcc version 4.0.1 20050727 (Red Hat 4.0.1-5)" from FC4 is affected, possibly others too. This changes the function subtly so that the buggy gcc transformation doesn't trigger.

Noticed in 2.6.15-git9 that CRASH_DUMP option is moved to top level. Moved CRASH_DUMP into "kernel options" next to KEXEC and this config option supports only for PPC64 at this time. Signed-off-by:

If optimizing for size (CONFIG_CC_OPTIMIZE_FOR_SIZE), allow gcc4 compilers to decide what to inline and what not - instead of the kernel forcing gcc to inline all the time. This requires several places that require to be inlined to be marked as such, previous patches in this series do that. Signed-off-by:

Mark a few VFS functions as mandatory inline (based on Al Viro's request); these must be inline due to stack usage issues during a recursive loop that happens during the recursive symlink resolution (symlink to a symlink to a symlink ..) This patch at this point does not change behavior and is for documentation purposes only (but this changes later in the series) Signed-off-by:

Arjan van de Ven <arjan@infradead.org> Mark a number of functions as 'must inline'. The functions affected by this patch need to be inlined because they use knowledge that their arguments are constant so that most of the function optimizes away. At this point this patch does not change behavior, it's for documentation only (and for future patches in the inline series) Signed-off-by: -

Allow gcc4 compilers to optimize unit-at-a-time. This flag enables gcc to "see" the entire C file before making optimisation decisions such as inline, which results in gcc making better decisions. One of the immediate effects of this is that static functions that are used only once now get inlined. gcc 3.4 has this flag as well, however gcc 3.x have a problem with inlining and stacks and as a result, enabling this flag there would cause excessive and unacceptable stack use. This problem is fixed in the gcc 4.x series. The x86-64 architecture already enables this feature so it's well tested already. Signed-off-by:

This patch is the first in a series that tries to optimize the kernel in terms of size (and thus cache behavior, both cpu and pagecache). This first patch changes __always_inline to be a forced inline instead of the "regular" inline it was on everything except alpha. This forced inline matches the intention of the define better as a matter of documentation. There is no change in behavior by this patch, since "inline" currently is mapped to a forced inline anyway.

No need for a file argument. If we'd really need it it's in vma->vm_file already. gbefb and sgivwfb used to set vma->vm_file to the file argument, but the kernel alrady did that. Signed-off-by:

Seems that the CS5530A chip used in Geode GX1 systems has some crazy feature that causes SMI traps when accessing the PCI configuration space of the video device. Various GX1 BIOSes seem to use this 'feature' to hide the real BARs of the device. This patch disables these traps (in an early PCI fixup) so that Linux sees the real, physical BARs and not the virtual ones provided by the BIOS. This should allow the GX1 framebuffer driver to work on more systems that have different BIOSes as the driver no longer guesses at what the virtual BARs mean. I'm not entirely sure it the correct solution as I can neither test regular VGA console nor the X's 'cyrix' video driver so there might be some breakage there -- probably best to get some more testers before applying it.

On a Dell Latitude CPi-A I noticed a strangeness wrt. the handling of an external monitor by the neomagic framebuffer driver, namely when the laptop is docked in a C/Dock II with the lid shut. A cold boot would result in the BIOS configuring the video chip to use the "external monitor only" mode, yet neofb would default to "internal LCD only". An attempt for a quick fix by using the Fn-F8 keystroke to toggle the display combination modes resulted in a reproductible hard lock, powering down being the only solution. The attached patch makes neofb probe the register for the current display mode, using that value as a default if nothing was specified as kernel/module parameter. Signed-off-by:

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=5854 Root cause: The dell_rbu driver creates entries in /sys/class/firmware/dell_rbu/ by calling request_firmware_nowait (without hotplug ) this function inturn starts a kernel thread which creates the entries in /sys/class/firmware/dell_rbu/loading , data and the thread waits on the user action to return control back to the callback fucntion of dell_rbu. The thread calls wait_on_completion which puts it in a D state until the user action happens. If there is no user action happening the load average goes up as the thread D state is taken in to account. Also after downloading the BIOS image the enrties go away momentarily but they are recreated from the callback function in dell_rbu. This causes the thread to get recreated causing the load average to permenently stay around 1. Fix: The dell_rbu also creates the entry /sys/devices/platform/dell_rbu/image_type at driver load time. The image type by default is mono if required the user can echo packet to image_type to make the BIOS update mechanism using packets. Also by echoing init in to image_type the /sys/class/firmware/dell_rbu entries can be created. The driver code was changed to not create /sys/class/firmware/dell_rbu entries during load time, and also to not create the above entries from the callback function. The entries are only created by echoing init to /sys/devices/platform/dell_rbu/image_type The user now needs to create the entries to download the image monolithic or packet. This fixes the issue since the kernel thread only is created when ever the user is ready to download the BIOS image; this minimizes the life span of the kernel thread and the load average goes back to normal.

fs/quota_v2.c can, under some conditions, issue a kernel message that says, in totality, 'failed read'. This patch does the following: 1) Gives a hint who issued the error message, so people reading the logs don't have to go grepping the entire kernel tree (with 11 false positives). 2) Say what amount of data we expected, and actually got.

The problem, reported in: http://bugzilla.kernel.org/show_bug.cgi?id=5859 and by various other email messages and lkml posts is that the cpuset hook in the oom (out of memory) code can try to take a cpuset semaphore while holding the tasklist_lock (a spinlock). One must not sleep while holding a spinlock. The fix seems easy enough - move the cpuset semaphore region outside the tasklist_lock region. This required a few lines of mechanism to implement. The oom code where the locking needs to be changed does not have access to the cpuset locks, which are internal to kernel/cpuset.c only. So I provided a couple more cpuset interface routines, available to the rest of the kernel, which simple take and drop the lock needed here (cpusets callback_sem). Signed-off-by:
