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
