2008-05-01x86: Fix 32-bit x86 MSI-X allocation leakagePJ Waskiewicz
commit 9d9ad4b51d2b29b5bbeb4011f5e76f7538119cf9 upstream This bug was introduced in the 2.6.24 lguest tree merge, where MSI-X vector allocation will eventually fail. The cause is the new bit array tracking used vectors is not getting cleared properly on IRQ destruction on the 32-bit APIC code. This can be seen easily using the ixgbe 10 GbE driver on multi-core systems by simply loading and unloading the driver a few times. Depending on the number of available vectors on the host system, the MSI-X allocation will eventually fail, and the driver will only be able to use legacy interrupts.

upstream commit ef1afd4d79f0479960ff36bb5fe6ec6eba1ebff2 commit 721fdf34167580ff98263c74cead8871d76936e6 Author: Kyle McMartin <kyle@shortfin.cabal.ca> Date: Thu Dec 6 09:32:15 2007 -0800 [PARISC] print more than one character at a time for pdc console introduced a subtle bug by accidentally removing the "static" from iodc_dbuf. This resulted in, what appeared to be, a trap without *current set to a task. Probably the result of a trap in real mode while calling firmware. Also do other misc clean ups. Since the only input from firmware is non blocking, share iodc_dbuf between input and output, and spinlock the only callers.

2008-04-18vmcoreinfo: add the symbol "phys_base"Ken'ichi Ohmichi
upstream commit: 629c8b4cdb354518308663aff2f719e02f69ffbe Fix the problem that makedumpfile sometimes fails on x86_64 machine. This patch adds the symbol "phys_base" to a vmcoreinfo data. The vmcoreinfo data has the minimum debugging information only for dump filtering. makedumpfile (dump filtering command) gets it to distinguish unnecessary pages, and makedumpfile creates a small dumpfile. On x86_64 kernel which compiled with CONFIG_PHYSICAL_START=0x0 and CONFIG_RELOCATABLE=y, makedumpfile fails like the following: # makedumpfile -d31 /proc/vmcore dumpfile The kernel version is not supported. The created dumpfile may be incomplete. _exclude_free_page: Can't get next online node. makedumpfile Failed. # The cause is the lack of the symbol "phys_base" in a vmcoreinfo data. If the symbol "phys_base" does not exist, makedumpfile considers an x86_64 kernel as non relocatable. As the result, makedumpfile misunderstands the physical address where the kernel is loaded, and it cannot translate a kernel virtual address to physical address correctly. To fix this problem, this patch adds the symbol "phys_base" to a vmcoreinfo data. Signed-off-by: Ken'ichi Ohmichi <oomichi@mxs.nes.nec.co.jp> Cc: "Eric W.

2008-04-18xen: fix UP setup of shared_infoJeremy Fitzhardinge
upstream commit: 2e8fe719b57bbdc9e313daed1204bb55fed3ed44 We need to set up the shared_info pointer once we've mapped the real shared_info into its fixmap slot. That needs to happen once the general pagetable setup has been done. Previously, the UP shared_info was set up one in xen_start_kernel, but that was left pointing to the dummy shared info. Unfortunately there's no really good place to do a later setup of the shared_info in UP, so just do it once the pagetable setup has been done.

2008-04-18xen: fix RMW when unmasking eventsJeremy Fitzhardinge
upstream commit: 04c44a080d2f699a3042d4e743f7ad2ffae9d538 xen_irq_enable_direct and xen_sysexit were using "andw $0x00ff, XEN_vcpu_info_pending(vcpu)" to unmask events and test for pending ones in one instuction. Unfortunately, the pending flag must be modified with a locked operation since it can be set by another CPU, and the unlocked form of this operation was causing the pending flag to get lost, allowing the processor to return to usermode with pending events and ultimately deadlock. The simple fix would be to make it a locked operation, but that's rather costly and unnecessary. The fix here is to split the mask-clearing and pending-testing into two instructions; the interrupt window between them is of no concern because either way pending or new events will be processed. This should fix lingering bugs in using direct vcpu structure access too.

2008-03-24S390 futex: let futex_atomic_cmpxchg_pt survive early functional tests.Heiko Carstens
a0c1e9073ef7428a14309cba010633a6cd6719ea "futex: runtime enable pi and robust functionality" introduces a test wether futex in atomic stuff works or not. It does that by writing to address 0 of the kernel address space. This will crash on older machines where addressing mode switching is enabled but where the mvcos instruction is not available. Page table walking is done by hand and therefore the code tries to access current->mm which is NULL. Therefore add an extra check, so we survive the early test.

[upsteam commit: a0ca9909] Thanks to Loic Prylli <loic@myri.com>, who originally proposed this idea. Always using legacy configuration mechanism for the legacy config space and extended mechanism (mmconf) for the extended config space is a simple and very logical approach. It's supposed to resolve all known mmconf problems. It still allows per-device quirks (tweaking dev->cfg_size). It also allows to get rid of mmconf fallback code.

2008-03-24x86: Clear DF before calling signal handlerAurelien Jarno
x86: Clear DF before calling signal handler The Linux kernel currently does not clear the direction flag before calling a signal handler, whereas the x86/x86-64 ABI requires that. This become a real problem with gcc version 4.3, which assumes that the direction flag is correctly cleared at the entry of a function. This patches changes the setup_frame() functions to clear the direction before entering the signal handler. This is a backport of patch e40cd10ccff3d9fbffd57b93780bee4b7b9bff51 ("x86: clear DF before calling signal handler") that has been applied in 2.6.25-rc.

2008-02-25x86_64: CPA, fix cache attribute inconsistency bugIngo Molnar
(no matching git id as the upstream code is rewritten) fix CPA cache attribute bug in v2.6.24. When phys_base is nonzero (when CONFIG_RELOCATABLE=y) then change_page_attr_addr() miscalculates the secondary alias address by -14 MB (depending on the configured offset). The default 64-bit kernels of Fedora and Ubuntu are affected: $ grep RELOCA /boot/config-2.6.23.9-85.fc8 CONFIG_RELOCATABLE=y $ grep RELOC /boot/config-2.6.22-14-generic CONFIG_RELOCATABLE=y and probably on many other distros as well. the bug affects all pages in the first 40 MB of physical RAM that are allocated by some subsystem that does ioremap_nocache() on them: if (__pa(address) < KERNEL_TEXT_SIZE) { Hence we might leave page table entries with inconsistent cache attributes around (pages mapped at both UnCacheable and Write-Back), and we can also set the wrong kernel text pages to UnCacheable. the effects of this bug can be random slowdowns and other misbehavior. If for example AGP allocates its aperture pages into the first 40 MB of physical RAM, then the -14 MB bug might mark random kernel texto pages as uncacheable, slowing down a random portion of the 64-bit kernel until the AGP driver is unloaded.

2008-02-25Disable G5 NAP mode during SMU commands on U3Benjamin Herrenschmidt
patch 592a607bbc053bc6f614a0e619326009f4b3829e in mainline. It appears that with the U3 northbridge, if the processor is in NAP mode the whole time while waiting for an SMU command to complete, then the SMU will fail. It could be related to the weird backward mechanism the SMU uses to get to system memory via i2c to the northbridge that doesn't operate properly when the said bridge is in napping along with the CPU. That is on U3 at least, U4 doesn't seem to be affected. This didn't show before NO_HZ as the timer wakeup was enough to make it work it seems, but that is no longer the case. This fixes it by disabling NAP mode on those machines while an SMU command is in flight.

When we set the MFGPT timer tick, there is a chance that we'll immediately assert an event. If for some reason the IRQ routing for this clock has been setup for some other purpose, then we could end up firing an interrupt into the SMM handler or worse. This rearranges the timer tick init function to initalize the handler before we set up the MFGPT clock to make sure that even if we get an event, it will go to the handler. Furthermore, in the handler we need to make sure that we clear the event, even if the timer isn't running.

2008-01-22[MIPS] Malta: Fix reading the PCI clock frequency on big-endianDmitri Vorobiev
The JMPRS register on Malta boards keeps a 32-bit CPU-endian value. The readw() function assumes that the value it reads is a little-endian 16-bit number. Therefore, using readw() to obtain the value of the JMPRS register is a mistake. This error leads to incorrect reading of the PCI clock frequency on big-endian during board start-up. Change readw() to __raw_readl(). This was tested by injecting a call to printk() and verifying that the value of the jmpr variable was consistent with current setting of the JP4 "PCI CLK" jumper.

2008-01-17CRIS v10: vmlinux.lds.S: ix kernel oops on boot and use common definesJesper Nilsson
- Move alignment to page size of init data outside ifdef for BLK_DEV_INITRD. The reservation up to page size of memory after init data was previously not done if BLK_DEV_INITRD was undefined. This caused a kernel oops when init memory pages were freed after startup, data placed in the same page as the last init memory would also be freed and reused, with disastrous results. - Use macros for initcalls and .text sections. - Replace hardcoded page size constant with PAGE_SIZE define. - Change include/asm-cris/page.h to use the _AC macro to instead of testing __ASSEMBLY__.
