putchar is using early_serial_base to check if port is initialized.
So we only assign it after early_serial_init() is called,
in case we need use VGA to debug early serial console.Also add display for port addr and baud.

form of early console.Also add back simple_guess_base(), otherwise those simple_strtoull(,,0)

This patch adds serial I/O support to the real-mode setup (very early
boot) printf(). It's useful for debugging boot code when running Linux
under KVM, for example. The actual code was lifted from early printk.Cc: Cyrill Gorcunov

Fujitsu slightly changed the DMI strings in their recent machines,
(for example the D2778) and this breaks the automatic loading of the
needed fschmd driver. Being more tolerant on string comparison fixes
the issue.This closes bug #15634:

The IT8720F has no VIN7 pin, so VCCH should always be routed
internally to VIN7 with an internal divider. Curiously, there still
is a configuration bit to control this, which means it can be set
incorrectly. And even more curiously, many boards out there are
improperly configured, even though the IT8720F datasheet claims that
the internal routing of VCCH to VIN7 is the default setting. So we
force the internal routing in this case.It turns out that all boards with the wrong setting are from Gigabyte,
so I suspect a BIOS bug. But it's easy enough to workaround in the
driver, so let's do it.Signed-off-by: Jean Delvare

When power_pmu_disable() removes the given event from a particular index into
cpuhw->event[], it shuffles down higher event[] entries. But, this array is
paired with cpuhw->events[] and cpuhw->flags[] so should shuffle them
similarly.If these arrays get out of sync, code such as power_check_constraints() will
fail. This caused a bug where events were temporarily disabled and then failed
to be re-enabled; subsequent code tried to write_pmc() with its (disabled) idx
of 0, causing a message "oops trying to write PMC0". This triggers this bug on
POWER7, running a miss-heavy test:perf record -e L1-dcache-load-misses -e L1-dcache-store-misses ./misstest

The bridge protocol lives dangerously by having incestuous relations
with the IP stack. In this instance an abomination has been created
where a bogus IPCB area from a bridged packet leads to a crash in
the IP stack because it's interpreted as IP options.This patch papers over the problem by clearing the IPCB area in that
particular spot. To fix this properly we'd also need to parse any
IP options if present but I'm way too lazy for that.Signed-off-by: Herbert Xu

We don't currently update the DPMS status of the connector (both in the
connector itself and the connector's DPMS property) in the fb helper
code. This means that if the kernel FB core has blanked the screen,
sysfs will still show a DPMS status of "on". It also means that when X
starts, it will try to light up the connectors, but the drm_crtc_helper
code will ignore the DPMS change since according to the connector, the
DPMS status is already on.Fixes https://bugs.freedesktop.org/show_bug.cgi?id=28436 (the annoying
"my screen was blanked when I started X and now it won't light up" bug).Signed-off-by: Jesse Barnes
