Is it something new in the x86.git tree?
no. A quick grep shows that it is in a file that _your_ changes in Linus' latest have touched:
arch/x86/kernel/cpu/mcheck/mce_amd_64.c

Kobject: change arch/x86/kernel/cpu/mcheck/mce_amd_64.c to use kobject_creat
x86.git changed nothing to cause a crash in kobject_uevent_env(), and nothing has changed anything near this code anyway.
We havent had a runtime (non-boot related) crash in x86.git for quite some time. It's rock solid and dependable, and the only significant change today were your upstream kobject commits.
