X-Git-Tag: v3.9-rc1~97^2~2^2~4 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=79fd50c67f91136add9726fb7719b57a66c6f763;p=pandora-kernel.git KVM: s390: Fix handling of iscs. There are two ways to express an interruption subclass: - As a bitmask, as used in cr6. - As a number, as used in the I/O interruption word. Unfortunately, we have treated the I/O interruption word as if it contained the bitmask as well, which went unnoticed so far as - (not-yet-released) qemu made the same mistake, and - Linux guest kernels don't check the isc value in the I/O interruption word for subchannel interrupts. Make sure that we treat the I/O interruption word correctly. Reviewed-by: Christian Borntraeger Signed-off-by: Cornelia Huck Signed-off-by: Gleb Natapov --- Reading git-diff-tree failed
