This fixes the setup of the alignment of the signal frame, so that all signal handlers are run with a properly aligned stack frame. The current code "over-aligns" the stack pointer so that the stack frame is effectively always mis-aligned by 4 bytes. But what we really want is that on function entry ((sp + 4) & 15) == 0, which matches what would happen if the stack were aligned before a "call" instruction. Signed-off-by: NMarkus F.X.J.

UML/x86_64 doesn't run when built with frame pointers disabled. There was an implicit frame pointer assumption in the stub segfault handler. With frame pointers disabled, UML dies on handling its first page fault. The container-of part of this is from Paolo Giarrusso <blaisorblade@yahoo.it>.

The following patch makes swsusp avoid the possible temporary corruption of page translation tables during resume on x86-64. This is achieved by creating a copy of the relevant page tables that will not be modified by swsusp and can be safely used by it on resume. The problem is that during resume on x86-64 swsusp may temporarily corrupt the page tables used for the direct mapping of RAM. If that happens, a page fault occurs and cannot be handled properly, which leads to the solid hang of the affected system. This leads to the loss of the system's state from before suspend and may result in the loss of data or the corruption of filesystems, so it is a serious issue. Also, it appears to happen quite often (for me, as often as 50% of the time). The problem is related to the fact that (at least) one of the PMD entries used in the direct memory mapping (starting at PAGE_OFFSET) points to a page table the physical address of which is much greater than the physical address of the PMD entry itself. Moreover, unfortunately, the physical address of the page table before suspend (i.e. the one stored in the suspend image) happens to be different to the physical address of the corresponding page table used during resume (i.e. the one that is valid right before swsusp_arch_resume() in arch/x86_64/kernel/suspend_asm.S is executed). Thus while the image is restored, the "offending" PMD entry gets overwritten, so it does not point to the right physical address any more (i.e. there's no page table at the address pointed to by it, because it points to the address the page table has been at during suspend). Consequently, if the PMD entry is used later on, and it _is_ used in the process of copying the image pages, a page fault occurs, but it cannot be handled in the normal way and the system hangs. In principle we can call create_resume_mapping() from swsusp_arch_resume() (ie. from suspend_asm.S), but then the memory allocations in create_resume_mapping(), resume_pud_mapping(), and resume_pmd_mapping() must be made carefully so that we use _only_ NosaveFree pages in them (the other pages are overwritten by the loop in swsusp_arch_resume()). Additionally, we are in atomic context at that time, so we cannot use GFP_KERNEL. Moreover, if one of the allocations fails, we should free all of the allocated pages, so we need to trace them somehow. All of this is done in the appended patch, except that the functions populating the page tables are located in arch/x86_64/kernel/suspend.c rather than in init.c. It may be done in a more elegan way in the future, with the help of some swsusp patches that are in the works now. [AK: move some externs into headers, renamed a function] Signed-off-by: NRafael J.

Commit 44456d37, between 2.6.13-rc3 and -rc4, was a "nice cleanup" which broke something. Revert the offending part. It broke because: a) because this part doesn't fall under the description b) the author didn't know what he was doing here c) the author didn't try to compile the existing code and see that it worked perfectly. d) the author didn't ask us what was happening e) you didn't either, and somebody there should have learned that UML is a bit different. In fact, UML is special in linking to host libc and using its includes. In particular, since host includes always define both __BIG_ENDIAN and __LITTLE_ENDIAN, ntohll() macros started thinking to be in a big-endian world; and on-disk compatibility was broken. Many thanks go to Nix for reporting the problem and correctly diagnosing an endianness problem. Btw, this patch restores the previous code, which worked; but the definitions would be uncorrect if used in kernelspace files. Next patch addresses that.

I've noticed a kernel hang during a storm of CMC interrupts, which was tracked down to the continual execution of the interrupt handler. There's code in the CMC handler that's supposed to disable CMC interrupts and switch to polling mode when it sees a bunch of CMCs. Because disabling CMCs across all CPUs isn't safe in interrupt context, the disable is done with a schedule_work(). But with continual CMC interrupts, the schedule_work() never gets executed. The following patch immediately disables CMC interrupts for the current CPU. This then allows (at least) one CPU to ignore CMC interrupts, execute the schedule_work() code, and disable CMC interrupts on the rest of the CPUs.

By allocating early memory for the firmware page tables, we can write over the beginning of the initrd image. So what we do now is: 1) Read in firmware translations table while still on the firmware's trap table. 2) Switch to Linux trap table. 3) Init bootmem. 4) Build firmware page tables using __alloc_bootmem(). And this keeps the initrd from being clobbered. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Older Macs which uses the VIA chip timers to calibrate the timebase used some code that wouldn't work if HZ wasn't divisible by 100... This fixes it at least for 250. Not totally perfect but should be enough for now (so it at least works with the default value which is now 250). There is still a potential issue with the core using CLOCK_TICK_RATE to maintain xtime and CLOCK_TICK_RATE value on ppc32 is pure crap, but that is a different problem, this patch at least brings us back to our previous situation.

Drop global bit from early low mappings Suggested by Linus, originally also proposed by Suresh. This fixes a race condition with early start of udev, originally tracked down by Suresh B. Siddha.
