+Subject: [PATCH] staging: xlr_net: Replace obsolete nlm_cop2_{enable,restore} macros
+
+Commit 64f6ebe63914 ("MIPS: Netlogic: rename nlm_cop2_save/restore")
+replaced nlm_cop2_enable with nlm_cop2_enable_irqsave and
+nlm_cop2_restore with nlm_cop2_disable_irqrestore but it did not
+update the xlr_net driver to use the new macros resulting into build
+problems like this:
+
+drivers/staging/netlogic/xlr_net.c: In function 'send_to_rfr_fifo':
+drivers/staging/netlogic/xlr_net.c:128:3: error: implicit declaration of
+function 'nlm_cop2_enable' [-Werror=implicit-function-declaration]
+mflags = nlm_cop2_enable();
+^
+drivers/staging/netlogic/xlr_net.c:130:3: error: implicit declaration of
+function 'nlm_cop2_restore' [-Werror=implicit-function-declaration]
+nlm_cop2_restore(mflags);
+
+Therefore rename these cases as well
