Because battery health monitoring should be done even when suspended,
it needs to wake up and suspend periodically. Thus, userspace battery
monitoring may incur too much overhead; every device and task is woken
up periodically. Charger Manager uses suspend-again to provide
in-suspend monitoring.This patch allows to monitor battery health in-suspend state.

The interrupt for ac on/off can be missed during boot time.
Check if online by seeing if we have power. We choose 0.5V
since this is high enough to avoid random reading from a
input that could be floating if no charger.Signed-off-by: Philip Rakity

In max17042_get_property(...), the values returned by
max17042_read_reg are directly assigned to the variables,
even if the read results in an error.This patch checks for the return code from max17042_read_reg and
exits the function if there is any error.Signed-off-by: Ramakrishna Pallala

Add rated capacity of the HP iPAQ hx4700 3.7V 3600mAh (359114-001)

register at 0x32 is 14; thus rated_capacities[14] = 3600.Signed-off-by: Paul Parsons

Since commit [e58aa3d2: genirq: Run irq handlers with interrupts
disabled], We run all interrupt handlers with interrupts disabled
and we even check and yell when an interrupt handler returns with
interrupts enabled (see commit [b738a50a: genirq: Warn when handler
enables interrupts]).So now this flag is a NOOP and can be removed.

events to be passed to drivers what are listed in the

Commit 4b239f458 ("x86-64, mm: Put early page table high") causes a S4
regression since 2.6.39, namely the machine reboots occasionally at S4
resume. It doesn't happen always, overall rate is about 1/20. But,
like other bugs, once when this happens, it continues to happen.This patch fixes the problem by essentially reverting the memory
assignment in the older way.Signed-off-by: Takashi Iwai

The ghash_update function passes a pointer to gf128mul_4k_lle which will
be NULL if ghash_setkey is not called or if the most recent call to
ghash_setkey failed to allocate memory. This causes an oops. Fix this
up by returning an error code in the null case.This is trivially triggered from unprivileged userspace through the
AF_ALG interface by simply writing to the socket without setting a key.The ghash_final function has a similar issue, but triggering it requires
a memory allocation failure in ghash_setkey _after_ at least one
successful call to ghash_update.BUG: unable to handle kernel NULL pointer dereference at 00000670
