xfrm: store xfrm_mode directly, not its address
This structure is now only 4 bytes, so its more efficient to cache a copy rather than its address. No significant size difference in allmodconfig vmlinux. With non-modular kernel that has all XFRM options enabled, this series reduces vmlinux image size by ~11kb. All xfrm_mode indirections are gone and all modes are built-in. before (ipsec-next master): text data bss dec filename 21071494 7233140 11104324 39408958 vmlinux.master after this series: 21066448 7226772 11104324 39397544 vmlinux.patched With allmodconfig kernel, the size increase is only 362 bytes, even all the xfrm config options removed in this series are modular. before: text data bss dec filename 15731286 6936912 4046908 26715106 vmlinux.master after this series: 15731492 6937068 4046908 26715468 vmlinux Signed-off-by: Florian Westphal <fw@strlen.de> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
