x86: add ->pre_time_init to x86_quirks

2008-07-20T07:25:52+00:00

so NUMAQ can use that to call numaq_pre_time_init()

This allows us to remove a NUMAQ special from arch/x86/kernel/setup.c.

(and paves the way to remove the NUMAQ subarch)

x86: extend and use x86_quirks to clean up NUMAQ code

2008-07-20T07:25:52+00:00

add these new x86_quirks methods:

	int *mpc_record;
	int (*mpc_apic_id)(struct mpc_config_processor *m);
	void (*mpc_oem_bus_info)(struct mpc_config_bus *m, char *name);
	void (*mpc_oem_pci_bus)(struct mpc_config_bus *m);
	void (*smp_read_mpc_oem)(struct mp_config_oemtable *oemtable,
                                    unsigned short oemsize);

... and move NUMAQ related mps table handling to numaq_32.c.

also move the call to smp_read_mpc_oem() to smp_read_mpc() directly.

Should not change functionality, albeit it would be nice to get it
tested on real NUMAQ as well ...

x86_64: add workaround for no %gs-based percpu

2008-07-16T08:58:13+00:00

As a stopgap until Mike Travis's x86-64 gs-based percpu patches are
ready, provide workaround functions for x86_read/write_percpu for
Xen's use.

Specifically, this means that we can't really make use of vcpu
placement, because we can't use a single gs-based memory access to get
to vcpu fields.  So disable all that for now.

x86: add early quirk support

2008-07-10T16:55:31+00:00

Add early quirks support.

In preparation of enabling the generic architecture to boot on a VISWS.

This will allow us to remove the VISWS subarch and all its complications.

x86, 64-bit: split x86_64_start_kernel

2008-07-08T11:11:06+00:00

Split x86_64_start_kernel() into two pieces:

   The first essentially cleans up after head_64.S.  It clears the
   bss, zaps low identity mappings, sets up some early exception
   handlers.

   The second part preserves the boot data, reserves the kernel's
   text/data/bss, pagetables and ramdisk, and then starts the kernel
   proper.

This split is so that Xen can call the second part to do the set up it
needs done.  It doesn't need any of the first part setups, because it
doesn't boot via head_64.S, and its redundant or actively damaging.
