2009-04-09tracing/syscalls: use a dedicated file headerFrederic Weisbecker
Impact: fix build warnings and possibe compat misbehavior on IA64 Building a kernel on ia64 might trigger these ugly build warnings: CC arch/ia64/ia32/sys_ia32.o In file included from arch/ia64/ia32/sys_ia32.c:55: arch/ia64/ia32/ia32priv.h:290:1: warning: "elf_check_arch" redefined In file included from include/linux/elf.h:7, from include/linux/module.h:14, from include/linux/ftrace.h:8, from include/linux/syscalls.h:68, from arch/ia64/ia32/sys_ia32.c:18: arch/ia64/include/asm/elf.h:19:1: warning: this is the location of the previous definition [...] sys_ia32.c includes linux/syscalls.h which in turn includes linux/ftrace.h to import the syscalls tracing prototypes. But including ftrace.h can pull too much things for a low level file, especially on ia64 where the ia32 private headers conflict with higher level headers. Now we isolate the syscall tracing headers in their own lightweight file.

2009-04-08[ARM] 5445/1: AT91: Remove flexible array from USBH platform dataJustin Waters
The flexible array in the USBH platform data is not safe to copy. The compiler will not allocate any extra memory for the non-init platform data structure (in the *_devices.c files) since it isn't given any defaults at compile time. When the probe function attempts to address that array, it will actually attempt to access data in an adjacent structure. Since there are currently no (known) implementations of the at91 USBH IP with more than 2 vbus pins, I am capping the value at 2. If somebody tries to assign more, then the compiler will produce a warning.

2009-04-08xen: mask XSAVE from cpuidJeremy Fitzhardinge
Xen leaves XSAVE set in cpuid, but doesn't allow cr4.OSXSAVE to be set. This confuses the kernel and it ends up crashing on an xsetbv instruction. At boot time, try to set cr4.OSXSAVE, and mask XSAVE out of cpuid it we can't. This will produce a spurious error from Xen, but allows us to support XSAVE if/when Xen does. This also factors out the cpuid mask decisions to boot time. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

2009-04-07x86 ACPI: Add support for Always Running APIC timerVenkatesh Pallipadi
Add support for Always Running APIC timer, CPUID_0x6_EAX_Bit2. This bit means the APIC timer continues to run even when CPU is in deep C-states. The advantage is that we can use LAPIC timer on these CPUs always, and there is no need for "slow to read and program" external timers (HPET/PIT) and the timer broadcast logic and related code in C-state entry and exit.

2009-04-07x86, setup: un-resequence mode setting for VGA 80x34 and 80x60 modesH. Peter Anvin
Impact: Fixes these modes on at least one system The rewrite of the setup code into C resequenced the font setting and register reprogramming phases of configuring nonstandard VGA modes which use 480 scan lines in text mode. However, there exists at least one board (Micro-Star MS-7383 version 2.0) on which this resequencing causes an unusable display. Revert to the original sequencing: set up 480-line mode, install the font, and then adjust the vertical end register appropriately. This failure was masked by the fact that the 480-line setup was broken until checkin 5f641356127712fbdce0eee120e5ce115860c17f (therefore this is not a -stable candidate bug fix.)
