[PATCH 6/7] x86, xsave: disable xsave in i387 emulation mode
xsave is broken for (!HAVE_HWFP). This is the case if config MATH_EMULATION is enabled, 'no387' kernel parameter is set and xsave exists. xsave will not work because x86/math-emu and xsave share the same memory. As this case can be treated as corner case we simply disable xsave then. Signed-off-by: Robert Richte... 21 Jul 2010 13:34

[PATCH 7/7] x86: removing boot_cpu_id variable
boot_cpu_id is there for historical reasons and was renamed to boot_cpu_physical_apicid in patch: c70dcb7 x86: change boot_cpu_id to boot_cpu_physical_apicid However, there are some remaining occurrences of boot_cpu_id that are never touched in the kernel and thus its value is always 0. This patch removes b... 21 Jul 2010 13:34

JBD2: Allow feature checks before journal recovery
> Before we start accessing a huge (> 16 TiB) OCFS2 volume, we need to confirm that its journal supports 64-bit offsets. So we need to check the journal's feature bits before recovering the journal. This is not possible with JBD2 at present, because the journal superblock (where the feature bits reside... 21 Jul 2010 14:43

sysfs: add entry to indicate network interfaces with random MAC address
| From: Andy Gospodarek <andy(a)greyhouse.net> | Date: Wednesday, July 21, 2010 08:07 am | | Agreed. The subtle difference between a locally assigned address that | is persistent and one that is random would be helpful. And just to point out that this case _does_ exist: the igb/igbvf drivers use random_ether... 23 Jul 2010 13:38
