When CONFIG_HPET_EMULATE_RTC is defined the external declaration of hpet_rtc_interrupt is redundant due to the inclusion of hpet.h. When !CONFIG_HPET_EMULATE_RTC we make it clear that hpet_rtc_interrupt is not used by defining it to return zero. Signed-off-by: NCarlos R.

vt.c DO_UPDATE macro checks if the console is visible but doesn't check if the console is blanked. In fact updating fbcon while the console is blanked is not only unnecessary but can even cause screen corruption. Therefore I am adding a simple check on console_blanked in DO_UPDATE.

On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit boundary. For example: u64 val = PAGE_ALIGN(size); always returns a value < 4GB even if size is greater than 4GB. The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for example): #define PAGE_SHIFT 12 #define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT) #define PAGE_MASK (~(PAGE_SIZE-1)) ... #define PAGE_ALIGN(addr) (((addr)+PAGE_SIZE-1)&PAGE_MASK) The "~" is performed on a 32-bit value, so everything in "and" with PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary. Using the ALIGN() macro seems to be the right way, because it uses typeof(addr) for the mask. Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in include/linux/mm.h.

Add run time control for receive DMA buffer fill level to allow application to control receive latency when using stream oriented serial protocols that pass receive data to application only after a DMA buffer fills. This was previously a compile time option, but run time control is needed when application changes data rate (and latency requirements) or uses different data rates on different ports.

Fix the Stallion driver's putchar() and break_ctl() ops and iStallion's putchar() to return values. Is it actually possible for putchar() or break_ctl() to be called with tty == NULL or can the check be discarded? Should stl_write() be returning 0 if tty->driver_data is NULL or tx.buf is NULL? Is this even possible? I've made Stallion's functions return -EINVAL as stli_breakctl() if the checks fail.
