- Make CONFIG_SMP depend on TT mode. Since SMP does not work in SKAS mode (it's still a TODO), add the dependency in the Kconfig. Also mark CONFIG_SMP as experimental. - Workaround kconfig warning: just for now (we wait for a "CONFIG_VIRTUAL_OS" to exclude physical hardware) create the CONFIG_INPUT option (fixed to N), to avoid complaints from make *config ARCH=um about it being undefined. - Mark HPPFS as broken and needing updates. - Update defconfig, both for new kernel options and for changes in the actual config. For instance, enable module support by default. - Update help text for some items and add a help to some other ones. Signed-off-by:

This patch is from John Rose <johnrose@austin.ibm.com>. The function __ioremap_explicit() misses a possible (obscure) case when reserving the imalloc area for the new region. This can result in the unexpected DLPAR-add failure for an I/O slot. The failure will be characterized by a kernel message resembling "could not obtain imalloc area for ea 0x..." Here's an explanation: At boot time, imalloc regions are created for the ranges of all PHBs. Upon removal of a child slot for one of these PHBs, the imalloc region is split so that the region for the child slot can be removed. A GFW testcase revealed the following scenario. A PHB is remapped at boot for virtual address range A through C. At boot, the partition owns a slot that spans from A to B. This slot is DLPAR-removed, leaving an imalloc region from B to C. At this point, the user DLPAR adds an EADS slot that was not present at boot, but is a child of the PHB. The new slot happens to have a range that directly matches the leftover PHB range, from B to C. The existing code does not expect this, so the operation fails. Signed-off-by:

This patch is from John Rose <johnrose@austin.ibm.com>. The patch below creates iommu_free_table(). Iommu tables are not currently freed in PPC64. This could cause a memory leak for DLPAR of an EADS slot. The function verifies that there are no outstanding TCE entries for the range of the table before freeing it. I added a call to iommu_free_table() to the code that dynamically removes a device node. This should be fairly symmetrical with the table allocation, which happens during dynamic addition of a device node. Signed-off-by:

This patch is from Linas Vepstas <linas@austin.ibm.com>. Race conditions during system shutdown after a firmware flash can sometimes lead to an invalid pointer deref (deref to freed memory). This patch fixes this. In addition, it makes sure that the proc entries created by the firmware flash module are removed when the module is unloaded. Signed-off-by:

When the EEH (enhanced i/o error handling) hardware on pSeries detects various kinds of PCI errors, it immediately freezes and isolates the slot of the offending PCI card. We get to know about that by noticing that reads from the device return all-1s, and then we have to do a firmware call to find out whether the all-1s value was due to a slot isolation. This patch adds a notifier so that other parts of the system (e.g. the RPA PCI hotplug driver) can know that a slot isolation event has occurred and take whatever recovery action is appropriate. The notifier is called in a workqueue function, although the read from the device that noticed the all-1s value may have been at interrupt level. As a precaution, if we keep trying to read from the device at interrupt level, and do 1000 reads without the workqueue getting a chance to run, we panic, on the grounds that we presumably have a badly-written driver which will spin forever in its interrupt routine, e.g. waiting for a bit in a device register to go to 0. This patch is based on an earlier patch by Linas Vepstas <linas@linas.org>. Signed-off-by:

This patch removes many sparse warnings from the xmon code. Mostly K&R function declarations and 0-instead-of-NULLs. There are still a whole bunch of warnings in xmon/ppc-opc.c, which is a copy of a file from binutils. Signed-off-by:

Only compile vio.c on iSeries and pSeries, since other PPC64 platforms (PowerMac) don't use virtual IO. The resulting #ifdefs in dma.c are kind of ugly, but at least contained, and I can't see a nicer way of doing it for the time being. Signed-off-by:

Stephen Smalley notes that send_sigurg isn't mediated by LSM in the same manner as send_sigio. Patch below is a slight modification of Stephen's original patch. It moves the security_file_send_sigiotask() hook into the sigio_perm(). The hook's fd and reason arguments are replaced with the signum. sigio_perm() and it's callers are updated to pass the signum through to the hook. In send_sigio case, the signum is simply fown->signum or SIGIO when signum is 0, however in send_sigurg the kernel doesn't use fown->signum, it always sends SIGURG.

Uses the zero length array which seems to be quite abundant throughout the tree to reduce the size of the zone padding to zero. 1536 before, 1152 afterwards for me. Also try to be a bit smarter about getting commonly accessed fields together, which surely can't be worse than before. Signed-off-by:

This allows for low-latency BKL contention even with preemption. Previously, since preemption is disabled over context switches, re-acquiring the kernel lock when resuming a process would be non-preemtible.

This will get rid of the stack recursion possibility that can occur if an IRQ happens to hit the IRQ return path right after we've reset preempt_count() to 0 and are about to disable interrupts again. Trivially fixed by just moving the preempt count update to inside the interrupt disable. This makes the current PREEMPT_ACTIVE method fully work for IRQ recursions.
