Hi, all. I want to dynamically use irqbalance on X86 processor. My design is like the following: 1) if we boot kernel with "noirqbalance", then irqbalance is always disabled. 2) if we boot kernel without "noirqbalance", we can enable/disable irqbalance in runtime. I create a proc_fs entry /proc/sys/kernel/irqbalance This symbol I adding is in file arch/i386/kernel/io_apic.c /proc/sys/kernel/irqbalance = 0 /* disable irqbalance in runtime */ /proc/sys/kernel/irqbalance = 1 /* enable i...

it is a macro from gettext, used to translate the string. Usually this should only be used on string constants. Gruss Bernd -

Allow for various sysctl settings to initially be set to more secure defaults. Why: While you can easily set these values at boot time with sysctl (and most distros do). -Its nice to be able to set their initial value. -It also allows someone who is unfamiliar with all the security knobs the kernel exposes to easily turn one on or off (or even read about what it does). -Another benefit is every time a new security feature comes out (mmap_min_addr for example) you don't have to change the setting ...

Hi, This series of patches is intended to eliminate some design problems with the hibernation userland interface. It contains the following changes: * allow the user space utilities to get the size of the image via ioctl * introduce ioctls to be used instead of SNAPSHOT_PMOPS * mark the SNAPSHOT_SET_SWAP_FILE ioctl as deprecated * introduce new ioctl definitions to replace the wrongly defined ones * move the definitions of hibernation ioctls to a separate header file located   in include/linux...

From: Rafael J. Wysocki <rjw@sisk.pl> Three ioctl numbers belonging to the hibernation userland interface, SNAPSHOT_ATOMIC_SNAPSHOT, SNAPSHOT_SET_IMAGE_SIZE, SNAPSHOT_AVAIL_SWAP, SNAPSHOT_GET_SWAP_PAGE, are defined in a wrong way (eg. not portable). Provide new ioctl numbers for these ioctls and mark the existing ones as deprecated. Signed-off-by: Rafael J.

From: Rafael J. Wysocki <rjw@sisk.pl> Modify the hibernation userland interface by adding two new ioctls to it, SNAPSHOT_PLATFORM_SUPPORT and SNAPSHOT_POWER_OFF, that can be used, respectively, to switch the hibernation platform support on/off and to make the kernel transition the system to the hibernation state (eg. ACPI S4) using the platform (eg. ACPI) driver. These ioctls are intended to replace the misdesigned SNAPSHOT_PMOPS ioctl, which from now is regarded as obsolete and will be rem...

Andrew, can you please put this in? Having these exports for syscalls around hsa been a long-time annoyance that can finally be fixed now. -

You might rename EXPORT_UNUSED_SYMBOL to EXPORT_UNUSED_SYMBOL_ADRIAN because AFAIK I am still the only person who was ever dumb enough to use it after you wanted me to do so... Everyone else is allowed to always add, remove and change exports as he likes, but I should go through this special process. It makes no sense (except for keeping me busy) to treat some patches I send special while changes made by other people that break the modules API are still allowed. Andrew, please define API ...

Andrew wants a deprecation period for these symbols where the few users are most likely doing something wrong when using them, but if someone e.g. changes the IRQ API in a way that breaks most external modules no deprecation period is required. If the kernel should get some module API stability processes like EXPORT_UNUSED_SYMBOL() deprecation periods have to be made mandatory for *all* API changes and removals. But forcing EXPORT_UNUSED_SYMBOL on me while allowing other people to do bigg...

The trick for finding the right defconfig is neat, but you forgot to provide an i686_defconfig. ;-) More seriously, cross compiling the defconfig is often useful, e.g. for testing the compilation of patches that touch multiple architectures, and this patch therefore chooses g5_defconfig if $(CROSS_COMPILE) is non-empty.

This patch adds support for the SEGA Dreamcast keyboard. Following suggestions from the inout maintainer it has been somewhat rewritten since the previous posting (http://lkml.org/lkml/2007/9/4/168).

On Sun, 9 Sep 2007 17:46:54 +0100 Hi, in general the code looks clean; great job on that. A few suggestions and comments to hopefully help this driver to become even better: First of all, I'm a little concerned about the lack of locking that this driver seems to have; what guarantees the integrity of the lists used in the driver? I wonder if you want to at least check if the work was really for you before returning IRQ_HANDLED.... -

Eliminating prototypes saves me from an extra go round of the edit-compile testcycle when I change the signature of a function. It probably doesn't I tried to place functions close together that seemed like they were called together and called from each other. It's hard to know, of course, because GCC will make its own decisions about inlining, for example. At the end of the day, this is an NP problem.

A guest context switch to an uncached cr3 can require allocation of shadow pages, but we only recycle shadow pages in kvm_mmu_page_fault().
