| | | | | | | | | | Sonny has noticed hotplug CPU on ppc64 is broken in 2.6.15-*. One of the problems is that htab_initialize_secondary is called when a cpu is being brought up, but it is marked __init.

| | | | | | | | | | | | | | Currently, we do not pass the correct start_pfn to e820_hole_size, to calculate holes. Following patch fixes that. The bug results in incorrect number of node_present_pages for each pgdat and causes ugly output in /sys and probably VM inbalances.

* [PATCH] Hostfs: update for new glibc - add missing symbol exportsPaolo 'Blaisorblade' Giarrusso2005-12-291-0/+5
| | | | | | | | | | | | Today, when compiling UML, I got warnings for two used unexported symbols: readdir64 and truncate64. Indeed, my glibc headers are aliasing readdir to readdir64 and truncate to truncate64 (and so on). I'm then adding additional exports. Since I've no idea if the symbols where always provided in the supported glibc's, I've added weak definitions too.

* [PATCH] uml: fix random segfaults at bootupPaolo 'Blaisorblade' Giarrusso2005-12-291-10/+12
| | | | | | | | | | | | | | | | | Don't use printk() where "current_thread_info()" is crap. Until when we switch to running on init_stack, current_thread_info() evaluates to crap. Printk uses "current" at times (in detail, &current is evaluated with CONFIG_DEBUG_SPINLOCK to check the spinlock owner task). And this leads to random segmentation faults. Exactly, what happens is that &current = *(current_thread_info()), i.e. round down $esp and dereference the value. I.e. access the stack below $esp, which causes SIGSEGV on a VM_GROWSDOWN vma (see arch/i386/mm/fault.c).

* powerpc: Fix i8259 cascade on pSeries with XICS interrupt controllerPaul Mackerras2005-12-221-18/+3
| | | | | | | | | | | | | It turns out that commit f9bd170a87948a9e077149b70fb192c563770fdf broke the cascade from XICS to i8259 on pSeries machines; specifically we ended up not ever doing the EOI on the XICS for the cascade. The result was that interrupts from the serial ports (and presumably any other devices using ISA interrupts) didn't get through. This fixes it and also simplifies the code, by doing the EOI on the XICS in the xics_get_irq routine after reading and acking the interrupt on the i8259.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Nicolas Pitre Strictly speaking, the NPTL kernel helpers are required for pre ARMv6 only. They are available on ARMv6+ as well for obvious compatibility reasons. However there are cases where extra memory barriers are needed when using an SMP ARMv6 machine but not on pre-ARMv6. This patch adds a memory barrier kernel helper that glibc can use as needed for pre-ARMv6 binaries to be forward compatible with an SMP kernel on ARMv6, as well as the necessary dmb instructions to the cmpxchg helper.

I think (and testing on some GCC versions shows) this patch avoids the fundamental issue which is behind this, namely gcc using the stack when we have just replaced it, behind gcc's back.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I see why the problem exists only on SN. SN uses a different hardware mechanism to purge TLB entries across nodes. It looks like there is a bug in the SN TLB flushing code. During context switch, kernel threads inherit the mm of the task that was previously running on the cpu. This confuses the code in sn2_global_tlb_purge(). The result is a missed TLB purge for the task that owns the "borrowed" mm. (I hit the problem running heavy stress where kswapd was purging code pages of a user task that woke kswapd. The user task took a SIGILL fault trying to execute code in the page that had been ripped out from underneath it).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The udelay() inline for ia64 uses the ITC. If CONFIG_PREEMPT is enabled and the platform has unsynchronized ITCs and the calling task migrates to another CPU while doing the udelay loop, then the effective delay may be too short or very, very long. This patch disables preemption around 100 usec chunks of the overall desired udelay time. This minimizes preemption-holdoffs. udelay() is now too big to be inline, move it out of line and export it.

Here is the original comment: I've got a PXA270 system that uses GPIO80 as nCS4. This system did hang on resume. Digging into the problem I found that the processor stalled immediately when restoring the GAFR2_U register which restored the alternate function for GPIO80. Since the GPDR registers were restored after the GAFR registers, the offending GPIO was configured as input at this point. Thus the alternate function that was in effect after restoring the GAFR was in fact the input function "MBREQ" instead of the output function "nCS4". The "PXA27x Processor Family Developer's Manual" (Footnote in Table 6-1 on page 6-3) states that: "The MBREQ alternate function must not be enabled until the PSSR[RDH] bit field is cleared. For more details, see Table 3-15, "PSSR Bit Definitions" on page 3-71." There is another note in the Developer's Manual (chapter 24.4.2 "GPIO operation as Alternate Function" on page 24-4) stating that: "Configuring a GPIO for an alternate function that is not defined for it causes unpredictable results." Since some GPIOs have no input function defined, and to prevent inadvertedly programming the MBREQ function on some pin, the GAFR registers should be restored after the GPDR registers have been restored. Additional provisions have to be made when the MBREQ function is actually required. The corresponding GAFR bits should not be restored with the regular GAFR restore, but must be set only after the PSSR bits have been cleared.
