parisc: Fix patch code locking and flushing
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. Since __patch_text_multiple is often called with interrupts disabled, it is better to directly call flush_kernel_dcache_range_asm and flush_kernel_icache_range_asm. This avoids an extra call. 3) The final call to flush_icache_range is unnecessary. Signed-off-by: John David Anglin <dave.anglin@bell.net> Signed-off-by: Helge Deller <deller@gmx.de>
