* x86: Add quirk to make Apple MacBook5,2 use reboot=pciPaul Mackerras2009-08-03
| | | | | | | | | | | | | | | | | | | The latest Apple MacBook (MacBook5,2) doesn't reboot successfully under Linux; neither the EFI reboot method nor the default method using the keyboard controller works (the system just hangs and doesn't reset). However, the method using the "PCI reset register" at 0xcf9 does work. This adds a quirk to detect this machine via DMI and force the reboot_type to BOOT_CF9. With this it reboots successfully without requiring a command-line option. Note that the EFI code forces reboot_type to BOOT_EFI when the machine is booted via EFI, but this overrides that since the core_initcall runs after the EFI initialization code.

* x86: Fix CPA memtype reserving in the set_pages_array*() casesThomas Hellstrom2009-08-03
| | | | | | | | | | | | | | | | | | | | The code was incorrectly reserving memtypes using the page virtual address instead of the physical address. Furthermore, the code was not ignoring highmem pages as it ought to. ( upstream does not pass in highmem pages yet - but upcoming graphics code will do it and there's no reason to not handle this properly in the CPA APIs.)

* x86, pat: Fix set_memory_wc related corruptionPallipadi, Venkatesh2009-07-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changeset 3869c4aa18835c8c61b44bd0f3ace36e9d3b5bd0 that went in after 2.6.30-rc1 was a seemingly small change to _set_memory_wc() to make it complaint with SDM requirements. But, introduced a nasty bug, which can result in crash and/or strange corruptions when set_memory_wc is used. One such crash reported here http://lkml.org/lkml/2009/7/30/94 Actually, that changeset introduced two bugs. * change_page_attr_set() takes &addr as first argument and can the addr value might have changed on return, even for single page change_page_attr_set() call. That will make the second change_page_attr_set() in this routine operate on unrelated addr, that can eventually cause strange corruptions and bad page state crash. * The second change_page_attr_set() call, before setting _PAGE_CACHE_WC, should clear the earlier _PAGE_CACHE_UC_MINUS, as otherwise cache attribute will not be WC (will be UC instead). The patch below fixes both these problems. Sending a single patch to fix both the problems, as the change is to the same line of code. The change to have a addr_copy is not very clean. But, it is simpler than making more changes through various routines in pageattr.c. A huge thanks to Jerome for reporting this problem and providing a simple test case that helped us root cause the problem.

* x86: fix section mismatch for i386 init codeRobert Richter2009-07-27
| | | | | | | | | | | | | | | | | | | | | Startup code for i386 in arch/x86/kernel/head_32.S is using the reference variable initial_code that is located in the .cpuinit.data section. If CONFIG_HOTPLUG_CPU is enabled, startup code is not in an init section and can be called later too. In this case the reference initial_code must be kept too. This patch fixes this. See below for the section mismatch warning. WARNING: vmlinux.o(.cpuinit.data+0x0): Section mismatch in reference from the variable initial_code to the function .init.text:i386_start_kernel() The variable __cpuinitdata initial_code references a function __init i386_start_kernel(). If i386_start_kernel is only used by initial_code then annotate i386_start_kernel with a matching annotation.

The right fix is to drop the port on tty->shutdown() but we can't yet do that due to sleep v non-sleeping rules. Instead do the next best thing and fix it up when we are not in -rc season.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Timer interrupts are excluded from being disabled during suspend. The clock events code manages the disabling of clock events on its own because the timer interrupt needs to be functional before the resume code reenables the device interrupts. The mfgpt timer request its interrupt without setting the IRQF_TIMER flag so suspend_device_irqs() disables it as well which results in a fatal resume failure. Adding IRQF_TIMER to the interupt flags when requesting the mrgpt timer interrupt solves the problem.

| * | x86: Add quirk for Intel DG45ID board to avoid low memory corruptionAlexey Fisher2009-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AMI BIOS with low memory corruption was found on Intel DG45ID board (Bug 13710). Add this board to the blacklist - in the (somewhat optimistic) hope of future boards/BIOSes from Intel not having this bug.

When the hwptr goes back to zero, the delta value has to be corrected with the buffer size. Otherwise this causes looping sounds. Signed-off-by: Takashi Iwai <tiwai@suse.de>

For example, # echo 9 > /proc/asound/card0/pcm0p/xrun_debug will record the position and other parameters at each period interrupt together with the normal XRUN debugging.

This screws up the recent PCM core code that tries to correct the position based on the irq timing. Now, when a backward irq position is detected, skip the update instead of rebasing. (This is almost the old behavior before 2.6.30.) Signed-off-by: Takashi Iwai <tiwai@suse.de>
