Subject[PATCH] um: tlb: Remove unused flush_tlb_mm_range function
Date
GCC 11.4.0 produces the following warning when compiling the kernel for
UML architecture (with UML defconfig):

arch/um/kernel/tlb.c:579:6: warning: no previous prototype for ‘flush_tlb_mm_range’ [-Wmissing-prototypes]
579 | void flush_tlb_mm_range(struct mm_struct *mm, unsigned long start,)

This function is not used anywhere. It is not exported with
`EXPORT_SYMBOL` either, and therefore it is not usable for dynamically
loaded modules. Remove this function.
