lguest: suppress interrupts for single insn, not range.

2015-03-24T01:22:08+00:00

The last patch reduced our interrupt-suppression region to one address, so simplify the code somewhat. Also, remove the obsolete undefined instruction ranges and the comment which refers to lguest_guest.S instead of head_32.S. Signed-off-by: Rusty Russell

lguest: map Switcher below fixmap.

2013-04-22T06:15:03+00:00

Now we've adjusted all the code, we can simply set switcher_addr to wherever it needs to go below the fixmaps, rather than asserting that it should be so. With large NR_CPUS and PAE, people were hitting the "mapping switcher would thwack fixmap" message. Reported-by: Paul Bolle Signed-off-by: Rusty Russell

lguest: assume Switcher text is a single page.

2013-04-22T06:01:36+00:00

ie. SHARED_SWITCHER_PAGES == 1. It is well under a page, and it's a minor simplification: it's nice to have *one* simplification in a patch series! Signed-off-by: Rusty Russell

lguest: prepare to make SWITCHER_ADDR a variable.

2013-04-22T06:01:33+00:00

We currently use the whole top PGD entry for the switcher, but that's hitting the fixmap in some configurations (mainly, large NR_CPUS). Introduce a variable, currently set to the constant. Signed-off-by: Rusty Russell

x86: Introduce GDT_ENTRY_INIT()

2009-08-08T15:44:11+00:00

GDT_ENTRY_INIT is static initializer of desc_struct. We already have similar macro GDT_ENTRY() but it's static initializer for u64 and it cannot be used for desc_struct. Signed-off-by: Akinobu Mita LKML-Reference: <20090718151219.GD11294@localhost.localdomain> Signed-off-by: Ingo Molnar

lguest: fix comment style

2009-07-30T06:33:45+00:00

I don't really notice it (except to begrudge the extra vertical space), but Ingo does. And he pointed out that one excuse of lguest is as a teaching tool, it should set a good example. Signed-off-by: Rusty Russell Cc: Ingo Molnar

lguest: PAE support

2009-06-12T12:57:08+00:00

This version requires that host and guest have the same PAE status. NX cap is not offered to the guest, yet. Signed-off-by: Matias Zabaljauregui Signed-off-by: Rusty Russell

x86: cleanup some remaining usages of NR_CPUS where s/b nr_cpu_ids

2009-01-03T18:00:55+00:00

Impact: Reduce future system panics due to cpumask operations using NR_CPUS Insure that code does not look at bits >= nr_cpu_ids as when cpumasks are allocated based on nr_cpu_ids, these extra bits will not be defined. Also some other minor updates: * change in to use cpu accessor function set_cpu_present() instead of directly accessing cpu_present_map w/cpu_clear() [arch/x86/kernel/reboot.c] * use cpumask_of() instead of &cpumask_of_cpu() [arch/x86/kernel/reboot.c] * optimize some cpu_mask_to_apicid_and functions.

x86: Fix ASM_X86__ header guards

2008-10-23T05:55:23+00:00

Change header guards named "ASM_X86__*" to "_ASM_X86_*" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints. Signed-off-by: H. Peter Anvin
