2008-08-20x86: fix oprofile + hibernation badnessAndi Kleen
Vegard Nossum reported oprofile + hibernation problems: > Now some warnings: > > ------------[ cut here ]------------ > WARNING: at /uio/arkimedes/s29/vegardno/git-working/linux-2.6/kernel/smp.c:328 s > mp_call_function_mask+0x194/0x1a0() The usual problem: the suspend function when interrupts are already disabled calls smp_call_function which is not allowed with interrupt off. But at this point all the other CPUs should be already down anyways, so it should be enough to just drop that. This patch should fix that problem at least by fixing cpu hotplug& suspend support.

2008-08-20x86, SGI UV: hardcode the TLB flush interrupt system vectorCliff Wickman
The UV TLB shootdown mechanism needs a system interrupt vector. Its vector had been hardcoded as 200, but needs to moved to the reserved system vector range so that it does not collide with some device vector. This is still temporary until dynamic system IRQ allocation is provided. But it will be needed when real UV hardware becomes available and runs 2.6.27.

2008-08-20x86: fix "kernel won't boot on a Cyrix MediaGXm (Geode)"Samuel Sieb
Cyrix MediaGXm/Cx5530 Unicorn Revision 1.19.3B has stopped booting starting at v2.6.22. The reason is this commit: > commit f25f64ed5bd3c2932493681bdfdb483ea707da0a > Author: Juergen Beisert <juergen@kreuzholzen.de> > Date: Sun Jul 22 11:12:38 2007 +0200 > > x86: Replace NSC/Cyrix specific chipset access macros by inlined functions. this commit activated a macro which was dormant before due to (buggy) macro side-effects. I've looked through various datasheets and found that the GXm and GXLV Geode processors don't have an incrementor. Remove the incrementor setup entirely. As the incrementor value differs according to clock speed and we would hope that the BIOS configures it correctly, it is probably the right solution.

2008-08-18x86, percpu: silence section mismatch warnings related to EARLY_PER_CPU ↵Marcin Slusarz
variables Quoting Mike Travis in "x86: cleanup early per cpu variables/accesses v4" (23ca4bba3e20c6c3cb11c1bb0ab4770b724d39ac): The DEFINE macro defines the per_cpu variable as well as the early map and pointer. It also initializes the per_cpu variable and map elements to "_initvalue". The early_* macros provide access to the initial map (usually setup during system init) and the early pointer. This pointer is initialized to point to the early map but is then NULL'ed when the actual per_cpu areas are setup. After that the per_cpu variable is the correct access to the variable. As these variables are NULL'ed before __init sections are dropped (in setup_per_cpu_maps), they can be safely annotated as __ref. This change silences following section mismatch warnings: WARNING: vmlinux.o(.data+0x46c0): Section mismatch in reference from the variable x86_cpu_to_apicid_early_ptr to the variable .init.data:x86_cpu_to_apicid_early_map The variable x86_cpu_to_apicid_early_ptr references the variable __initdata x86_cpu_to_apicid_early_map If the reference is valid then annotate the variable with __init* (see linux/init.h) or name the variable: *driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console, WARNING: vmlinux.o(.data+0x46c8): Section mismatch in reference from the variable x86_bios_cpu_apicid_early_ptr to the variable .init.data:x86_bios_cpu_apicid_early_map The variable x86_bios_cpu_apicid_early_ptr references the variable __initdata x86_bios_cpu_apicid_early_map If the reference is valid then annotate the variable with __init* (see linux/init.h) or name the variable: *driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console, WARNING: vmlinux.o(.data+0x46d0): Section mismatch in reference from the variable x86_cpu_to_node_map_early_ptr to the variable .init.data:x86_cpu_to_node_map_early_map The variable x86_cpu_to_node_map_early_ptr references the variable __initdata x86_cpu_to_node_map_early_map If the reference is valid then annotate the variable with __init* (see linux/init.h) or name the variable: *driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console, Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Cc: Mike Travis <travis@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-08-18x86: fix i486 suspend to disk CR4 oopsDavid Fries
arch/x86/power/cpu_32.c __save_processor_state calls read_cr4() only a i486 CPU doesn't have the CR4 register. Trying to read it produces an invalid opcode oops during suspend to disk. Use the safe rc4 reading op instead. If the value to be written is zero the write is skipped. arch/x86/power/hibernate_asm_32.S done: swapped the use of %eax and %ecx to use jecxz for the zero test and jump over store to %cr4. restore_image: s/%ecx/%eax/ to be consistent with done: In addition to __save_processor_state, acpi_save_state_mem, efi_call_phys_prelog, and efi_call_phys_epilog had checks added (acpi restore was in assembly and already had a check for non-zero). There were other reads and writes of CR4, but MCE and virtualization shouldn't be executed on a i486 anyway. Signed-off-by: David Fries <david@fries.net> Acked-by: H.

2008-08-18x86: correct register constraints for 64-bit atomic operationsMathieu Desnoyers
x86_64 add/sub atomic ops does not seems to accept integer values bigger than 32 bits as immediates. Intel's add/sub documentation specifies they have to be passed as registers. The only operations in the x86-64 architecture which accept arbitrary 64-bit immediates is "movq" to any register; similarly, the only operation which accept arbitrary 64-bit displacement is "movabs" to or from al/ax/eax/rax. http://gcc.gnu.org/onlinedocs/gcc-4.3.0/gcc/Machine-Constraints.html states : e 32-bit signed integer constant, or a symbolic reference known to fit that range (for immediate operands in sign-extending x86-64 instructions). Z 32-bit unsigned integer constant, or a symbolic reference known to fit that range (for immediate operands in zero-extending x86-64 instructions). Since add/sub does sign extension, using the "e" constraint seems appropriate. It applies to 2.6.27-rc, 2.6.26, 2.6.25...

A loop counter is set up at the high value and decremented by page size. However, the loop is only done once as the sense of the conditional branch at the loop end does not match the setup/decrement.

2008-08-16Move sysctl check into debugging section and don't make it default yAndi Kleen
I noticed that sysctl_check.o was the largest object file in a allnoconfig build in kernel/*. 36243 0 0 36243 8d93 kernel/sysctl_check.o This is because it was default y and && EMBEDDED. But I don't really see a need for a non kernel developer to have their sysctls checked all the time. So move the Kconfig into the kernel debugging section and also drop the default y and the EMBEDDED check.

2008-08-16Fix header export of videodev2.h, ivtv.h, ivtvfb.hDavid Woodhouse
The exported copy of videodev2.h contains this line: #define #include <sys/time.h> This is because for some reason it defines __user for itself -- despite the fact that we remove all instances of __user when exporting headers. _All_ pointers in userspace are user pointers. Fix it by removing the unnecessary '#define __user' from the file. The new headers ivtv.h and ivtvfb.h would have the same problem... if whoever put them there had actually remembered to add them to the Kbuild file while he was at it. Fix those too, and export them as was presumably intended. Note that includes of <linux/compiler.h> are also stripped by the header export process, so those don't need to be conditional.

2008-08-16[ARM] pxafb: fix the warning of incorrect lccr when lcd_conn is specifiedEric Miao
The newly introduced "lcd_conn" field for connected LCD panel type will cause the original code to generate the warnings of incorrect lccr*. This is unnecessary since well encoded LCD_* flags will not generate incorrect combinition of lccr* bits. Skip the check if "lcd_conn" is specified.
