* | | [PATCH] epoll_pwait()Davide Libenzi2006-10-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the epoll_pwait system call, that extend the event wait mechanism with the same logic ppoll and pselect do. The definition of epoll_pwait is: int epoll_pwait(int epfd, struct epoll_event *events, int maxevents, int timeout, const sigset_t *sigmask, size_t sigsetsize); The difference between the vanilla epoll_wait and epoll_pwait is that the latter allows the caller to specify a signal mask to be set while waiting for events. Hence epoll_pwait will wait until either one monitored event, or an unmasked signal happen. If sigmask is NULL, the epoll_pwait system call will act exactly like epoll_wait. For the POSIX definition of pselect, information is available here: http://www.opengroup.org/onlinepubs/009695399/functions/select.html Signed-off-by: Davide Libenzi <davidel@xmailserver.org> Cc: David Woodhouse <dwmw2@infradead.org> Cc: Andi Kleen <ak@muc.de> Cc: Michael Kerrisk <mtk-manpages@gmx.net> Cc: Ulrich Drepper <drepper@redhat.com> Cc: Roland McGrath <roland@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* | | [PATCH] uml: allow finer tuning for host VMSPLIT settingPaolo 'Blaisorblade' Giarrusso2006-10-111-15/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that various memory splits are enabled, add a config option allowing the user to compile UML for its need - HOST_2G_2G allowed to choose either 3G/1G or 2G/2G, and enabling it reduced the usable virtual memory. Detecting this at run time should be implemented in the future, but we must make the stop-gap measure work well enough (this is valid in _many_ cases).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On a 64bit Uml, if run under "setarch i386" (which a user did), uname() currently returns the obtained i686 as machine - fix that.

The two problems were: *) x86 code, when 386 is selected, checks at runtime boot_cpuflags, which we do not have. *) 3Dnow support for memcpy() et al. does not compile currently and fixing this is not trivial, so simply disable it; with this change, if one selects MK7 UML compiles (while it did not).

* | | [PATCH] uml: make UML_SETJMP always safePaolo 'Blaisorblade' Giarrusso2006-10-111-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If enable is moved by GCC in a register its value may not be preserved after coming back there with longjmp(). So, mark it as volatile to prevent this; this is suggested (it seems) in info gcc, when it talks about -Wuninitialized. I re-read this and it seems to say something different, but I still believe this may be needed.

* | | [PATCH] uml: correct removal of pte_mkexecPaolo 'Blaisorblade' Giarrusso2006-10-111-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Correct commit 5906e4171ad61ce68de95e51b773146707671f80 - this makes more sense: we turn pte_mkexec + pte_wrprotect to pte_mkread. However, due to a bug in pte_mkread, it does the exact same thing as pte_mkwrite, so this patch improves the code but does not change anything in practice. The pte_mkread bug is fixed separately, as it may have big impact.

* | | [PATCH] mm: use symbolic names instead of indices for zone initialisationMel Gorman2006-10-119-27/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Arch-independent zone-sizing is using indices instead of symbolic names to offset within an array related to zones (max_zone_pfns). The unintended impact is that ZONE_DMA and ZONE_NORMAL is initialised on powerpc instead of ZONE_DMA and ZONE_HIGHMEM when CONFIG_HIGHMEM is set. As a result, the the machine fails to boot but will boot with CONFIG_HIGHMEM turned off. The following patch properly initialises the max_zone_pfns[] array and uses symbolic names instead of indices in each architecture using arch-independent zone-sizing. Two users have successfully booted their powerpcs with it (one an ibook G4). It has also been boot tested on x86, x86_64, ppc64 and ia64. Please merge for 2.6.19-rc2. Credit to Benjamin Herrenschmidt for identifying the bug and rolling the first fix. Additional credit to Johannes Berg and Andreas Schwab for reporting the problem and testing on powerpc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the old "powersurge" SMP powermacs, the second CPU is started up by sending it an IPI, which has the side effect of stopping the timebase clock (so the secondary CPU's timebase can be synchronized with the primary's). The routine that did this used udelay, which will hang forever when the timebase is stopped, since udelay now spins until the timebase reaches a certain value. The end result is that the kernel would hang when bringing up the second CPU. This fixes it by using a simple loop which just does a fixed number of iterations to generate the delay. These old systems were all clocked at around 200 MHz or so, so a fixed number of iterations is acceptable. Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IDE driver will pick up the PCI IRQ for both channels on Maple despite the fact that it's in legacy mode. This works around it by "hiding" the PCI IRQ of the AMD8111 IDE controller when it's configured in legacy mode on the Maple platform, thus causing the driver to call pci_get_legacy_ide_irq() which will return the correct interrupts for both channels.

* | [PATCH] x86_64 irq: Scream but don't die if we receive an unexpected irqEric W. Biederman2006-10-091-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to code bugs or misbehaving hardware it is possible that we can receive an interrupt that we have not mapped into a linux irq. Calling BUG when that happens is very rude, and if the problem is mild enough prevents anything else from getting done. So instead of calling BUG just scream loudly about the problem and continue running. We don't have enough knowledge to know which interrupt triggered this behavior so we don't acknowledge it. This will likely prevent a recurrence of the problem by jamming up the works with an unacknowledged interrupt. If the interrupt was something important it is quite possible that nothing productive will happen past this point. But it is now at least possible to keep working if the kernel can survive without the interrupt we dropped on the floor. Solutions like irqpoll should generally make dropped irqs non-fatal.
