When acpi_evaluate_object() is passed ACPI_ALLOCATE_BUFFER,
the caller must kfree the returned buffer if AE_OK is returned.

The callers of wmi_get_event_data() pass ACPI_ALLOCATE_BUFFER,
and thus must check its return value before accessing
or kfree() on the buffer.

Emphasize that that wmi_install_notify_handler() returns an acpi_status
rather than -errno by by testing ACPI_SUCCESS(), ACPI_FAILURE().

No functional change in this patch, but this confusion caused a bug in dell-wmi.

follow 0/-E convention

wmi_install_notify_handler() returns an acpi_error,
but dell_wmi_init() needs return a -errno style error.

This fixes a "start_kernel(): bug: interrupts were enabled early".

rtc_cmos now takes care of initializing the ISA RTC and reading the
current time and date from it; there's no need to repeat that here,
thereby causing interrupts to be enabled too early.

With some of the cache rework an address aliasing optimization was added,
but this managed to fail on certain mappings resulting in pages with
PG_dcache_dirty set never writing back their dcache lines. This patch
reverts to the earlier behaviour of simply always writing back when the
dirty bit is set.
