Problem Details: Commit b0b0c0a26e84 "nfsd: add proc file listing kernel's gss_krb5 enctypes" added an nunnecessary dependency of nfsd on the auth_rpcgss module. It's a little ad hoc, but since the only piece of information nfsd needs from rpcsec_gss_krb5 is a single static string, one solution is just to share it wit...

Analyze and fix the following issue in the Linux kernel code: x86/amd-iommu: Fix 3 possible endless loops
Problem Details: The driver contains several loops counting on an u16 value where the exit-condition is checked against variables that can have values up to 0xffff. In this case the loops will never exit. This patch fixed 3 such loops. Cc: stable@kernel.org Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
