760	vreg's can be modified by an arbitrary thread running on another CPU	Jakub Jermář	Jakub Jermář	On amd64 and ia32, `vreg_init()` creates a user-writable page for each CPU with the intention to offer this page via the FS, resp. GS, register as an array of virtual registers that can be used by uspace to implement eg. TLS. Unfortunately, this page can be accessed and written to also from other CPUs without any limits.	defect	accepted	major		helenos/kernel/amd64	mainline
