From: Matt Parnell <parwok at gmail.com> drm/nouveau: Add DRM_NOUVEAU_DEBUG option Sometimes we have DEBUG_FS enabled, but don't want output from certain modules. Most modules make this an option, so I figured that Nouveau needed it too. I also made it exlicit that CONSOLE_FRAMEBUFFER is needed for textmode use with KMS.

debugfs.h protects itself from an undefined DEBUG_FS, so it is not necessary to check it in the driver code or the Makefile. The driver code had been updated for this, but the Makefile had missed the update.

Hi Jon, perfect instructions, thank you very much. I used them and after some tests they worked. Here is what I did. Maybe someone could use it completely: ------------------------------------------------------------ Install helpers: apt-get install kernel-package ncurses-dev fakeroot wget bzip2 Go to usr directory: cd /usr/src wget

This adds support for systemd socket-based activation in the ssh-agent. When using socket activation, the -a flag value must match the socket path provided by systemd, as a sanity check. Support for this feature is enabled by the --with-systemd configure flag. --- Something tells me upstream would not be interested in this patch, but as it may be useful on linux, I'm submitting it here.

Hi All, this is the fairlock patchset. You can apply them and build successfully. patches are based on linux-next qspinlock can avoid waiter starved issue. It has about the same speed in single-thread and it can be much faster in high contention situations especially when the spinlock is embedded within the data structure to be protected. v8 -> v9: mv qspinlocm config entry to

The 4-patch series to follow this email extends KVM-hypervisor and Linux guest running on KVM-hypervisor to support pv-ticket spinlocks, based on Xen's implementation. One hypercall is introduced in KVM hypervisor,that allows a vcpu to kick another vcpu out of halt state. The blocking of vcpu is done using halt() in (lock_spinning) slowpath.
