x86: Merge early kernel reserve for 32bit and 64bit

2013-01-30T03:32:58Z

They are the same, and we could move them out from head32/64.c to setup.c. We are using memblock, and it could handle overlapping properly, so we don't need to reserve some at first to hold the location, and just need to make sure we reserve them before we are using memblock to find free mem to use.

x86, boot: Sanitize boot_params if not zeroed on creation

2013-01-29T09:22:17Z

Use the new sentinel field to detect bootloaders which fail to follow protocol and don't initialize fields in struct boot_params that they do not explicitly initialize to zero. Based on an original patch and research by Yinghai Lu. Changed by hpa to be invoked both in the decompression path and in the kernel proper; the latter for the case where a bootloader takes over decompression.

x86, realmode: Move ACPI wakeup to unified realmode code

2012-05-08T18:46:05Z

Migrated ACPI wakeup code to the real-mode blob. Code existing in .x86_trampoline can be completely removed. Static descriptor table in wakeup_asm.S is courtesy of H. Peter Anvin.

memblock: Kill memblock_init()

2011-12-08T18:22:07Z

memblock_init() initializes arrays for regions and memblock itself; however, all these can be done with struct initializers and memblock_init() can be removed. This patch kills memblock_init() and initializes memblock with struct initializer. The only difference is that the first dummy entries don't have .nid set to MAX_NUMNODES initially. This doesn't cause any behavior difference. Signed-off-by: Tejun Heo Cc: Benjamin Herrenschmidt Cc: Yinghai Lu Cc: Russell King Cc: Michal Simek Cc: Paul Mundt Cc: "David S.

memblock, x86: Replace memblock_x86_reserve/free_range() with generic ones

2011-07-14T18:47:53Z

Other than sanity check and debug message, the x86 specific version of memblock reserve/free functions are simple wrappers around the generic versions - memblock_reserve/free(). This patch adds debug messages with caller identification to the generic versions and replaces x86 specific ones and kills them. arch/x86/include/asm/memblock.h and arch/x86/mm/memblock.c are empty after this change and removed.

x86: Introduce pci_map_biosrom()

2011-03-15T22:34:15Z

The isci driver needs to retrieve its preboot OROM image which contains necessary runtime parameters like platform specific sas addresses and phy configuration. There is no ROM BAR associated with this area, instead we will need to scan legacy expansion ROM space. 1/ Promote the probe_roms_32 implementation to x86-64 2/ Add a facility to find and map an adapter rom by pci device (according to PCI Firmware Specification Revision 3.0) Signed-off-by: Dave Jiang LKML-Reference: <20110308183226.6246.90354.stgit@localhost6.localdomain6> Signed-off-by: Dan Williams Signed-off-by: H.

x86, trampoline: Common infrastructure for low memory trampolines

2011-02-18T05:02:43Z

Common infrastructure for low memory trampolines. This code installs the trampolines permanently in low memory very early. It also permits multiple pieces of code to be used for this purpose. This code also introduces a standard infrastructure for computing symbol addresses in the trampoline code. The only change to the actual SMP trampolines themselves is that the 64-bit trampoline has been made reusable -- the previous version would overwrite the code with a status variable; this moves the status variable to a separate location.
