Heiko Carstens 602490b469 s390/vx: fix save/restore of fpu kernel context 
[ Upstream commit e6b2dab418 ]

The KERNEL_FPR mask only contains a flag for the first eight vector
registers. However floating point registers overlay parts of the first
sixteen vector registers.

This could lead to vector register corruption if a kernel fpu context uses
any of the vector registers 8 to 15 and is interrupted or calls a
KERNEL_FPR context. If that context uses also vector registers 8 to 15,
their contents will be corrupted on return.

Luckily this is currently not a real bug, since the kernel has only one
KERNEL_FPR user with s390_adjust_jiffies() and it is only using floating
point registers 0 to 2.

Fix this by using the correct bits for KERNEL_FPR.

Fixes: 7f79695cc1 ("s390/fpu: improve kernel_fpu_[begin|end]")
