2008-08-12hugetlb: call arch_prepare_hugepage() for surplus pagesGerald Schaefer
The s390 software large page emulation implements shared page tables by using page->index of the first tail page from a compound large page to store page table information. This is set up in arch_prepare_hugepage(), which is called from alloc_fresh_huge_page_node(). A similar call to arch_prepare_hugepage() is missing for surplus large pages that are allocated in alloc_buddy_huge_page(), which breaks the software emulation mode for (surplus) large pages on s390. This patch adds the missing call to arch_prepare_hugepage(). It will have no effect on other architectures where arch_prepare_hugepage() is a nop. Also, use the correct order in the error path in alloc_fresh_huge_page_node().

2008-08-12IB/ehca: Discard double CQE for one WRAlexander Schmidt
Under rare circumstances, the ehca hardware might erroneously generate two CQEs for the same WQE, which is not compliant to the IB spec and will cause unpredictable errors like memory being freed twice. To avoid this problem, the driver needs to detect the second CQE and discard it. For this purpose, introduce an array holding as many elements as the SQ of the QP, called sq_map. Each sq_map entry stores a "reported" flag for one WQE in the SQ. When a work request is posted to the SQ, the respective "reported" flag is set to zero. After the arrival of a CQE, the flag is set to 1, which allows to detect the occurence of a second CQE. The mapping between WQE / CQE and the corresponding sq_map element is implemented by replacing the lowest 16 Bits of the wr_id with the index in the queue map. The original 16 Bits are stored in the sq_map entry and are restored when the CQE is passed to the application.

2008-08-12IB/ehca: Check idr_find() return valueAlexander Schmidt
The idr_find() function may fail when trying to get the QP that is associated with a CQE, e.g. when a QP has been destroyed between the generation of a CQE and the poll request for it. In consequence, the return value of idr_find() must be checked and the CQE must be discarded when the QP cannot be found.

2008-08-12IB/ehca: Repoll CQ on invalid opcodeAlexander Schmidt

2008-08-12IB/ehca: Update qp_state on cached modify_qp()Alexander Schmidt
Since the introduction of the port auto-detect mode for ehca, calls to modify_qp() may be cached in the device driver when the ports are not activated yet. When a modify_qp() call is cached, the qp state remains untouched until the port is activated, which will leave the qp in the reset state. In the reset state, however, it is not allowed to post SQ WQEs, which confuses applications like ib_mad. The solution for this problem is to immediately set the qp state as requested by modify_qp(), even when the call is cached.

2008-08-12[IA64] Ensure cpu0 can access per-cpu variables in early boot codeTony Luck
ia64 handles per-cpu variables a litle differently from other architectures in that it maps the physical memory allocated for each cpu at a constant virtual address (0xffffffffffff0000). This mapping is not enabled until the architecture specific cpu_init() function is run, which causes problems since some generic code is run before this point. In particular when CONFIG_PRINTK_TIME is enabled, the boot cpu will trap on the access to per-cpu memory at the first printk() call so the boot will fail without the kernel printing anything to the console. Fix this by allocating percpu memory for cpu0 in the kernel data section and doing all initialization to enable percpu access in head.S before calling any generic code. Other cpus must take care not to access per-cpu variables too early, but their code path from start_secondary() to cpu_init() is all in arch/ia64 Signed-off-by: Tony Luck <tony.luck@intel.com>

2008-08-12fix spinlock recursion in hvc_consoleChristian Borntraeger
commit 611e097d7707741a336a0677d9d69bec40f29f3d Author: Christian Borntraeger <borntraeger@de.ibm.com> hvc_console: rework setup to replace irq functions with callbacks introduced a spinlock recursion problem. request_irq tries to call the handler if the IRQ is shared. The irq handler of hvc_console calls hvc_poll and hvc_kill which might take the hvc_struct spinlock. Therefore, we have to call request_irq outside the spinlock. We can move the notifier_add safely outside the spinlock as ->data must not be changed by the backend. Otherwise, tty_hangup would fail anyway.

2008-08-12modules: extend initcall_debug functionality to the module loaderArjan van de Ven
The kernel has this really nice facility where if you put "initcall_debug" on the kernel commandline, it'll print which function it's going to execute just before calling an initcall, and then after the call completes it will 1) print if it had an error code 2) checks for a few simple bugs (like leaving irqs off) and 3) print how long the init call took in milliseconds. While trying to optimize the boot speed of my laptop, I have been loving number 3 to figure out what to optimize... ... and then I wished that the same thing was done for module loading. This patch makes the module loader use this exact same functionality; it's a logical extension in my view (since modules are just sort of late binding initcalls anyway) and so far I've found it quite useful in finding where things are too slow in my boot.

2008-08-12lguest: use get_user_pages_fast() instead of get_user_pages()Rusty Russell
Using a simple page table thrashing program I measure a slight improvement. The program creates five processes. Each touches 1000 pages then schedules the next process. We repeat this 1000 times. As lguest only caches 4 cr3 values, this rebuilds a lot of shadow page tables requiring virt->phys mappings. Before: 5.93 seconds After: 5.40 seconds (Counts of slow vs fastpath in this usage are 6092 and 2852462 respectively.) And more importantly for lguest, the code is simpler.

2008-08-12intel/agp: rewrite GTT on resumeKeith Packard
On my Intel chipset (965GM), the GTT is entirely erased across suspend/resume. This patch simply re-plays the current mapping at resume time to restore the table.=20 I noticed this once I started relying on persistent GTT mappings across VT switch in our GEM work -- the old X server and DRM code carefully unbind all memory from the GTT on VT switch, but GEM does not bother. I placed the list management and rewrite code in the generic layer on the assumption that it will be needed on other hardware, but I did not add the rewrite call to anything other than the Intel resume function. Keep a list of current GATT mappings. At resume time, rewrite them into the GATT. This is needed on Intel (at least) as the entire GATT is cleared across suspend/resume.
