This change fixes the following: 1) The flags variable is not initialized. Always use raw_spin_lock_irqsave and raw_spin_unlock_irqrestore to serialize patching. 2) flush_kernel_vmap_range is primarily intended for DMA flushes. The whole cache flush in flush_kernel_vmap_range is only possible when interrupts are enabled on SMP machines. Since __patch_text_multiple calls flush_kernel_vmap_range with interrupts disabled, it is better to directly call flush_kernel_dcache_range_asm and flush_kernel_icache_range_asm. 3) The final call to flush_icache_range is unnecessary. Tested with `[PATCH, V3] parisc: Rewrite cache flush code for PA8800/PA8900' change on rp3440, c8000 and c3750 (32 and 64-bit). Note by Helge: This patch had been temporarily reverted shortly before v5.18-rc6 in order to fix boot issues. Now it can be re-applied.
