x86: Fix section mismatches in mpparse

2009-04-12T10:32:18Z

Impact: fix section mismatch In arch/x86/kernel/mpparse.c, smp_reserve_bootmem() has been called and also refers to a function which is in .init section. Thus causes the first warning. And check_irq_src() also requires an __init, because it refers to an .init section. Signed-off-by: Rakib Mullick Cc: Andrew Morton LKML-Reference: Signed-off-by: Ingo Molnar

x86: mpparse.c introduce check_physptr helper function

2009-03-21T08:45:43Z

To reduce the size of the oversized function __get_smp_config() There should be no impact to functionality. Signed-off-by: Jaswinder Singh Rajput

x86: mpparse.c introduce smp_dump_mptable helper function

2009-03-21T08:45:11Z

smp_read_mpc() and replace_intsrc_all() can use same smp_dump_mptable() Signed-off-by: Jaswinder Singh Rajput

x86: mpparse: clean up code by introducing a few helper functions, fix

2009-03-19T07:52:13Z

Impact: fix boot crash This fixes commit a6830278568a8bb9758aac152db15187741e0113. Signed-off-by: Jaswinder Singh Rajput Cc: Yinghai Lu LKML-Reference: <1237403503.22438.21.camel@ht.satnam> Signed-off-by: Ingo Molnar

x86: mpparse: clean up code by introducing a few helper functions

2009-03-18T16:15:05Z

Impact: cleanup Refactor the MP-table parsing code via the introduction of the following helper functions: skip_entry() smp_reserve_bootmem() check_irq_src() check_slot() To simplify the code flow and to reduce the size of the following oversized functions: smp_read_mpc(), smp_scan_config(). There should be no impact to functionality. Signed-off-by: Jaswinder Singh Rajput Signed-off-by: Ingo Molnar

x86: clean up output resulting from update_mptable option

2009-03-13T01:37:19Z

Impact: cleanup Without apic=verbose, using the update_mptable option would result in garbled and confusing output due to the inconsistent use of printk() vs apic_printk(). Signed-off-by: Jan Beulich LKML-Reference: <49B914B6.76E4.0078.0@novell.com> Signed-off-by: Ingo Molnar

x86: reserve exact size of mptable

2009-03-04T19:55:04Z

Impact: save a bit of RAM Get the exact size for the reserve_bootmem() call. Signed-off-by: Yinghai Lu Cc: Andrew Morton LKML-Reference: <49AE4922.605@kernel.org> Signed-off-by: Ingo Molnar

x86: ioremap mptable

2009-03-04T19:55:04Z

Impact: fix boot with mptable above max_low_mapped Try to use early_ioremap() to map MPC to make sure it works even it is at the end of ram. Signed-off-by: Yinghai Lu Cc: Andrew Morton LKML-Reference: <49AE4901.3090801@kernel.org> Signed-off-by: Ingo Molnar Reported-and-tested-by: Kevin O'Connor

x86: check mptable physptr with max_low_pfn on 32bit

2009-02-23T06:41:31Z

Impact: fix early crash on LinuxBIOS systems Kevin O'Connor reported that Coreboot aka LinuxBIOS tries to put mptable somewhere very high, well above max_low_pfn (below which BIOSes generally put the mptable), causing a panic. The BIOS will probably be changed to be compatible with older Linus versions, but nevertheless the MP-spec does not forbid an MP-table in arbitrary system RAM, so make sure it all works even if the table is in an unexpected place. Check physptr with max_low_pfn * PAGE_SIZE. Reported-by: Kevin O'Connor Signed-off-by: Yinghai Lu Cc: Stefan Reinauer Cc: coreboot@coreboot.org Signed-off-by: Ingo Molnar

x86, apic: remove genapic.h
