[PATCH 2/2] powerpc/powernv: Enable POWER8 doorbell IPIs

This patch enables POWER8 doorbell IPIs on powernv. Since doorbells can only IPI within a core, we test to see when we can use doorbells and if not we fall back to XICS. This also enables hypervisor doorbells to wakeup us up from nap/sleep via the LPCR PECEDH bit. Based on tests by Anton, the be

[PATCH 1/2] powerpc/cpuidle: Only clear LPCR decrementer wakeup bit on fast sleep entry

Currently when entering fastsleep we clear all LPCR PECE bits. This patch changes it to only clear the decrementer bit (ie. PECE1), which is the only bit we really need to clear here. This is needed if we want to set other wakeup causes like the PECEDH bit so we can use hypervisor doorbells on po

[PATCHv7 2/6] ppc/cell: use get_unused_fd_flags(0) instead of get_unused_fd()

Macro get_unused_fd() is used to allocate a file descriptor with default flags. Those default flags (0) can be "unsafe": O_CLOEXEC must be used by default to not leak file descriptor across exec(). Instead of macro get_unused_fd(), function get_unused_fd_flags() (or anon_inode_getfd()) should be u

[PATCHv7 0/6] Getting rid of get_unused_fd() / enable close-on-exec

TL;DR; These are mostly obvious patches, easy to review, easy to apply: you want them in the kernel. Now. And get_unused_fd() deserves to die. Act today ! Hi, Please find the seventh revision of my patchset to remove get_unused_fd() macro in order to help subsystems to use get_unused_fd_flags()
