From 2e65d1f6eecc176ba1341541b5f41edd7eb4346a Mon Sep 17 00:00:00 2001 From: David Howells Date: Mon, 6 Jun 2011 15:47:05 +0100 Subject: MN10300: Fix one of the kernel debugger cacheflush variants One of the kernel debugger cacheflush variants escaped proper testing. Two of the labels are wrong, being derived from the code that was copied to construct the variant. The first label results in the following assembler message: AS arch/mn10300/mm/cache-dbg-flush-by-reg.o arch/mn10300/mm/cache-dbg-flush-by-reg.S: Assembler messages: arch/mn10300/mm/cache-dbg-flush-by-reg.S:123: Error: symbol `debugger_local_cache_flushinv_no_dcache' is already defined And the second label results in the following linker message: arch/mn10300/mm/built-in.o:(.text+0x1d39): undefined reference to `mn10300_local_icache_inv_range_reg_end' arch/mn10300/mm/built-in.o:(.text+0x1d39): relocation truncated to fit: R_MN10300_PCREL16 against undefined symbol `mn10300_local_icache_inv_range_reg_end' To test this file the following configuration pieces must be set: CONFIG_AM34=y CONFIG_MN10300_CACHE_WBACK=y CONFIG_MN10300_DEBUGGER_CACHE_FLUSH_BY_REG=y CONFIG_MN10300_CACHE_MANAGE_BY_REG=y CONFIG_AM34_HAS_CACHE_SNOOP=n Signed-off-by: David Howells Signed-off-by: Linus Torvalds --- arch/mn10300/mm/cache-dbg-flush-by-reg.S | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'arch/mn10300/mm') diff --git a/arch/mn10300/mm/cache-dbg-flush-by-reg.S b/arch/mn10300/mm/cache-dbg-flush-by-reg.S index 665919f2ab62..a775ea5d7cee 100644 --- a/arch/mn10300/mm/cache-dbg-flush-by-reg.S +++ b/arch/mn10300/mm/cache-dbg-flush-by-reg.S @@ -120,14 +120,14 @@ debugger_local_cache_flushinv_one: # conditionally purge this line in all ways mov d1,(L1_CACHE_WAYDISP*0,a0) -debugger_local_cache_flushinv_no_dcache: +debugger_local_cache_flushinv_one_no_dcache: # # now try to flush the icache # mov CHCTR,a0 movhu (a0),d0 btst CHCTR_ICEN,d0 - beq mn10300_local_icache_inv_range_reg_end + beq debugger_local_cache_flushinv_one_end LOCAL_CLI_SAVE(d1) -- cgit v1.2.1
