| | * acer-wmi: support integer return type from WMI methodsLee, Chun-Yi2011-05-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Acer WMID_GUID1/2 method's return value was declared to integer type on Gateway notebook.

The problem is the load_scm_model_init() calls msi_laptop_input_setup() which is an __init function, but load_scm_model_init() lacks a __init annotation. This patch add __init on load_scm_model_init() to avoid warning message.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Quite a few functions that get called from the tlb gather code require that preemption must be disabled. So disable preemption inside of the called functions instead. The only drawback is that rcu_table_freelist_finish() doesn't get necessarily called on the cpu(s) that filled the free lists. So we may see a delay, until we finally see an rcu callback. However over time this shouldn't matter. So we get rid of lots of "BUG: using smp_processor_id() in preemptible" messages.

This got inconsistent with 2d42552d "[S390] merge page_test_dirty and page_clear_dirty". Result is that we read/write storage keys from random pages and do not have a working dirty bit tracking at all. E.g. SetPageUpdate() doesn't clear the dirty bit of requested pages, which for example ext4 doesn't like very much and panics after a while.
