MIPS: idle: Remove leftover __pastwait symbol and its references
The __pastwait symbol was only used by the address_is_in_r4k_wait_irqoff function but this is no longer used since the SMTC removal in commit b633648c5ad3 ('MIPS: MT: Remove SMTC support'). That symbol also led to build failures under certain random configuration due to the way the compiler compiled the r4k_wait_irqoff function. If that function was called multiple times, the __pastwait symbol was redefined breaking the build like this: CHK include/generated/compile.h CC arch/mips/kernel/idle.o {standard input}: Assembler messages: {standard input}:527: Error: symbol `__pastwait' is already defined Link: http://www.linux-mips.org/cgi-bin/mesg.cgi?a=linux-mips&i=1244879922.24479.30.camel%40falcon Signed-off-by: Markos Chandras <markos.chandras@imgtec.com> Cc: linux-mips@linux-mips.org Cc: Markos Chandras <markos.chandras@imgtec.com> Patchwork: https://patchwork.linux-mips.org/patch/7791/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
