From 7d97277b754d3ee098a5ec69b6aaafb00c94e2f2 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Sat, 7 Feb 2009 15:39:41 -0800 Subject: acpi/x86: introduce __apci_map_table, v4 to prevent wrongly overwriting fixmap that still want to use. ACPI used to rely on low mappings being all linearly mapped and grew a habit: it never really unmapped certain kinds of tables after use. This can cause problems - for example the hypothetical case when some spurious access still references it. v2: remove prev_map and prev_size in __apci_map_table v3: let acpi_os_unmap_memory() call early_iounmap too, so remove extral calling to early_acpi_os_unmap_memory v4: fix typo in one acpi_get_table_with_size calling Signed-off-by: Yinghai Lu Acked-by: Len Brown Signed-off-by: Ingo Molnar --- include/linux/acpi.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include/linux/acpi.h') diff --git a/include/linux/acpi.h b/include/linux/acpi.h index 6fce2fc2d12..d59f0fa4d77 100644 --- a/include/linux/acpi.h +++ b/include/linux/acpi.h @@ -79,6 +79,7 @@ typedef int (*acpi_table_handler) (struct acpi_table_header *table); typedef int (*acpi_table_entry_handler) (struct acpi_subtable_header *header, const unsigned long end); char * __acpi_map_table (unsigned long phys_addr, unsigned long size); +void __init __acpi_unmap_table(char *map, unsigned long size); int early_acpi_boot_init(void); int acpi_boot_init (void); int acpi_boot_table_init (void); -- cgit v1.2.3 From 970ec1a8213cd1a1ea29972ebbe4575a8b30bca1 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Sun, 15 Feb 2009 14:06:13 -0800 Subject: [IA64] fix __apci_unmap_table Impact: fix build error to fix: tip/arch/ia64/kernel/acpi.c:203: error: conflicting types for '__acpi_unmap_table' tip/include/linux/acpi.h:82: error: previous declaration of '__acpi_unmap_table' was here tip/arch/ia64/kernel/acpi.c:203: error: conflicting types for '__acpi_unmap_table' tip/include/linux/acpi.h:82: error: previous declaration of '__acpi_unmap_table' was here Signed-off-by: Yinghai Lu Cc: Jeremy Fitzhardinge Signed-off-by: Ingo Molnar --- include/linux/acpi.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'include/linux/acpi.h') diff --git a/include/linux/acpi.h b/include/linux/acpi.h index d59f0fa4d77..78199151c00 100644 --- a/include/linux/acpi.h +++ b/include/linux/acpi.h @@ -79,7 +79,7 @@ typedef int (*acpi_table_handler) (struct acpi_table_header *table); typedef int (*acpi_table_entry_handler) (struct acpi_subtable_header *header, const unsigned long end); char * __acpi_map_table (unsigned long phys_addr, unsigned long size); -void __init __acpi_unmap_table(char *map, unsigned long size); +void __acpi_unmap_table(char *map, unsigned long size); int early_acpi_boot_init(void); int acpi_boot_init (void); int acpi_boot_table_init (void); -- cgit v1.2.3 From 9f5404d8ea90bfa4d58a3936e5a3d0d28cecf60f Mon Sep 17 00:00:00 2001 From: Kenji Kaneshige Date: Mon, 9 Feb 2009 16:00:04 +0900 Subject: PCI/ACPI: rename pci_osc_control_set() - Rename pci_osc_control_set() to acpi_pci_osc_control_set() according to the other API names in drivers/acpi/pci_root.c. - Move _OSC related definitions to include/linux/acpi.h because _OSC related API is implemented in drivers/acpi/pci_root.c now.
