[PATCH] Staging: speakup: Fix getting port information

Commit f79b0d9c223c ("staging: speakup: Fixed warning instead of ") broke the port information in the speakup driver: SERIAL_PORT_DFNS only gets defined if asm/serial.h is included, and no other header includes asm/serial.h. We here make sure serialio.c does get the arch-specific definition of

[PATCH] staging: ion : Donnot wakeup kswapd in ion system alloc

Since ion alloc can be called by userspace,eg gralloc. When it is called frequently, the efficiency of kswapd is to low. And the reclaimed memory is too lower. In this way, the kswapd can use to much cpu resources. With 3.5GB DMA Zone and 0.5 Normal Zone. pgsteal_kswapd_dma 9364140

[PATCH] staging: ion: make the pte default none PTE_RDONLY

The page is already alloc at ion_alloc function, ion_mmap map the alloced pages to user-space. The default prot can be PTE_RDONLY. Take a look at here: set_pte_at() arch/arm64/include/asm: if (pte_dirty(pte) && pte_write(pte)) pte_val(pte) &= ~PTE_RDONLY;
