2009-07-27mm: Pass virtual address to [__]p{te,ud,md}_free_tlb()Benjamin Herrenschmidt29-67/+91
mm: Pass virtual address to [__]p{te,ud,md}_free_tlb() Upcoming paches to support the new 64-bit "BookE" powerpc architecture will need to have the virtual address corresponding to PTE page when freeing it, due to the way the HW table walker works. Basically, the TLB can be loaded with "large" pages that cover the whole virtual space (well, sort-of, half of it actually) represented by a PTE page, and which contain an "indirect" bit indicating that this TLB entry RPN points to an array of PTEs from which the TLB can then create direct entries. Thus, in order to invalidate those when PTE pages are deleted, we need the virtual address to pass to tlbilx or tlbivax instructions. The old trick of sticking it somewhere in the PTE page struct page sucks too much, the address is almost readily available in all call sites and almost everybody implemets these as macros, so we may as well add the argument everywhere. I added it to the pmd and pud variants for consistency.

I had to disable first stage of unaligned handler which is used only for noMMU kernel and the whole work is done when interrupt is enabled.

2009-07-24[S390] vdso: clock_gettime of CLOCK_THREAD_CPUTIME_ID with noexec=onMartin Schwidefsky1-2/+9
The combination of noexec=on and a clock_gettime call with clock id CLOCK_THREAD_CPUTIME_ID is broken. The vdso code switches to the access register mode to get access to the per-cpu data structure to execute the magic ectg instruction. After the ectg instruction the code always switches back to the primary mode but for noexec=on the correct mode is the secondary mode. The effect of the bug is that the user space program looses the access to all mappings without PROT_EXEC, e.g. the stack. The problem is fixed by restoring the mode that has been active before the switch to the access register mode. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2009-07-24[S390] hibernation: fix register corruption on machine checksHeiko Carstens2-33/+25
swsusp_arch_suspend() actually saves all cpu register contents on hibernation. Machine checks must be disabled since swsusp_arch_suspend() stores register contents to their lowcore save areas. That's the same place where register contents on machine checks would be saved. To avoid register corruption disable machine checks. We must also disable machine checks in the new psw mask for program checks, since swsusp_arch_suspend() may generate program checks.

2009-07-24[S390] hibernation: fix lowcore handlingHeiko Carstens2-7/+10
Our swsusp_arch_suspend() backend implementation disables prefixing by setting the contents of the prefix register to 0. However afterwards common code functions are called which might access percpu data structures. Since the lowcore contains e.g. the percpu base pointer this isn't a good idea. So fix this by copying the hibernating cpu's lowcore to absolute address zero. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2009-07-24x86: geode: Mark mfgpt irq IRQF_TIMER to prevent resume failureThomas Gleixner1-1/+1
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.

2009-07-18vmlinux.lds.h: restructure BSS linker script macrosTim Abbott1-1/+1
The BSS section macros in vmlinux.lds.h currently place the .sbss input section outside the bounds of [__bss_start, __bss_end]. On all architectures except for microblaze that handle both .sbss and __bss_start/__bss_end, this is wrong: the .sbss input section is within the range [__bss_start, __bss_end]. Relatedly, the example code at the top of the file actually has __bss_start/__bss_end defined twice; I believe the right fix here is to define them in the BSS_SECTION macro but not in the BSS macro. Another problem with the current macros is that several architectures have an ALIGN(4) or some other small number just before __bss_stop in their linker scripts. The BSS_SECTION macro currently hardcodes this to 4; while it should really be an argument. It also ignores its sbss_align argument; fix that. mn10300 is the only user at present of any of the macros touched by this patch. It looks like mn10300 actually was incorrectly converted to use the new BSS() macro (the alignment of 4 prior to conversion was a __bss_stop alignment, but the argument to the BSS macro is a start alignment). So fix this as well. I'd like acks from Sam and David on this one. Also CCing Paul, since he has a patch from me which will need to be updated to use BSS_SECTION(0, PAGE_SIZE, 4) once this gets merged.

2009-07-17Revert "Neither asm/types.h nor linux/types.h is required for ↵Aurelien Jarno1-0/+2
arch/ia64/include/asm/fpu.h" asm/fpu.h uses the __IA64_UL macro which is declared in asm/types.h, so this include is really required. Without it, GNU libc fails to build.
