Re: [PATCH v20 04/23] LSM: Use lsmblob in security_kernel_act_as

Change the security_kernel_act_as interface to use a lsmblob structure in place of the single u32 secid in support of module stacking. Change its only caller, set_security_override, to do the same. Change that one's only caller, set_security_override_from_ctx, to call it with the new parameter type. The security module hook is unchanged, still taking a secid. The infrastructure passes the correct entry from the lsmblob. lsmblob_init() is used to fill the lsmblob structure, however this will be removed later in the series when security_secctx_to_secid() is undated to provide a lsmblob instead of a secid.
