+Subject: [PATCH 3.7-rc8] MIPS: MT: fix build with CONFIG_UIDGID_STRICT_TYPE_CHECKS=y
+
+When CONFIG_UIDGID_STRICT_TYPE_CHECKS is enabled, plain integer checking
+between different uids/gids is explicitely turned into a build failure
+by making the k{uid,gid}_t types a structure containing a value:
+
+arch/mips/kernel/mips-mt-fpaff.c: In function 'check_same_owner':
+arch/mips/kernel/mips-mt-fpaff.c:53:22: error: invalid operands to
+binary == (have 'kuid_t' and 'kuid_t')
+arch/mips/kernel/mips-mt-fpaff.c:54:15: error: invalid operands to
+binary == (have 'kuid_t' and 'kuid_t')
+
+This problem got introduced with commit 17c04139 (MIPS: MT: Fix FPU affinity.)
+
+In order to ensure proper comparison between uids, using the helper
+function uid_eq() which performs the right thing whenever this config
+option is turned on or off.

+Ralf, I think you might want to sneak this into 3.7-rc8 if possible at all.
