config VXFS_FS tristate "FreeVxFS file system support (VERITAS VxFS(TM) compatible)" depends on BLOCK help FreeVxFS is a file system driver that support the VERITAS VxFS(TM) file system format. VERITAS VxFS(TM) is the standard file system of SCO UnixWare (and possibly others) and optionally available for Sunsoft Solaris, HP-UX and many other operating systems. However these particular OS implementations of vxfs may differ in on-disk data endianess and/or superblock offset. The vxfs module has been tested with SCO UnixWare and HP-UX B.10.20 (pa-risc 1.1 arch.) Currently only readonly access is supported and VxFX versions 2, 3 and 4. Tests were performed with HP-UX VxFS version 3. NOTE: the file system type as used by mount(1), mount(2) and fstab(5) is 'vxfs' as it describes the file system format, not the actual driver. There is a userspace utility for HP-UX logical volumes which makes creating HP-UX logical volumes easy from HP-UX disk block device file or regular file with image of the disk. See: https://sourceforge.net/projects/linux-vxfs/ To compile this as a module, choose M here: the module will be called freevxfs. If unsure, say N. nds-private-remove net-next plumbingsTobias Klauser

perf/x86/intel/rapl: Make package handling more robust
The package management code in RAPL relies on package mapping being available before a CPU is started. This changed with: 9d85eb9119f4 ("x86/smpboot: Make logical package management more robust") because the ACPI/BIOS information turned out to be unreliable, but that left RAPL in broken state. This was not noticed because on a regular boot all CPUs are online before RAPL is initialized. A possible fix would be to reintroduce the mess which allocates a package data structure in CPU prepare and when it turns out to already exist in starting throw it away later in the CPU online callback. But that's a horrible hack and not required at all because RAPL becomes functional for perf only in the CPU online callback. That's correct because user space is not yet informed about the CPU being onlined, so nothing caan rely on RAPL being available on that particular CPU. Move the allocation to the CPU online callback and simplify the hotplug handling. At this point the package mapping is established and correct. This also adds a missing check for available package data in the event_init() function.
