Currently all CTs are treated and illegal. There are two ways to report the fault back to the application. If the application used the record form ("icswx.") then the architected "reject" is emulated. If the application did not used the record form ("icswx") then it is selectable by config whether the failure is silent (as architected) or a SIGILL is generated. In all cases pr_warn() is used to log the bad CT. Signed-off-by: Jimi Xenidis Signed-off-by: Benjamin Herrenschmidt --- Reading git-diff-tree failed
