In order to clean up the mmc_erase() function and do some optimization
for erase size alignment, factor out the guts of erase size alignment
into mmc_align_erase_size() function.

In most cases the 'card->erase_size' is power of 2, then the round_up/down()
function is more efficient than '%' operation when the 'card->erase_size' is
power of 2.

Before issuing mmc_erase() function, users always have checked if it can
erase with mmc_can_erase/trim/discard() function, thus remove the redundant
erase checking in mmc_erase() function.

This patch exchanges the two loop for collecting the percpu
statistics data. This can reduce cache misses by going through
all the items of each cpu sequentially.

This patch exchanges the two loop for collecting the percpu statistics
data. This can aggregate the data by going through all the items of each
cpu sequentially. Then snmp_seq_show is split into 2 parts to avoid build
warning "the frame size" larger than 1024.

This driver creates a userspace leds driver similar to uinput.
New leds are created by opening /dev/uleds and writing a uleds_user_dev
struct. A new leds class device is registered with the name given in the
struct. Reading will return a single byte that is the current brightness.

Oleg, thank you.
the key point is for CONFIG_PREEMPT_NONE=y, if sched_exec needs migrate the
current,
migration_cpu_stop doesn't migrate the task(current) at all, it means that the
stopper thread does some
unuseful works in this scenario.
finally,the stopper thread calls cpu_stop_signal_done()
The patch adds RTC support for Loongson1C board, and enable
the external crystal when the RTC is first powered up.
