* sh: Support PCI IO access of SH7780 base boards.Nobuhiro Iwamatsu2007-11-302-4/+4
| | | | | | | | | The IO access of PCI is not supported in R7780RP and the MS7780SE board now. The support of the IO access mode of e100 and a lot of IDE chips becomes possible by fixing the code.

| * x86 setup: don't recalculate ss:esp unless really necessaryJens Rottmann2007-11-291-25/+16Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to work around old LILO versions providing an invalid ss register, the current setup code always sets up a new stack, immediately following .bss and the heap. But this breaks LOADLIN. This rewrite of the workaround checks for an invalid stack (ss!=ds) first, and leaves ss:sp alone otherwise (apart from aligning esp). [hpa note: LOADLIN has a number of arbitrary hard-coded limits that are being pushed up against. Without some major revision of LOADLIN itself it will not be sustainable keeping it alive. This gives it another brief lease on life, however. This patch also helps the cmdline truncation problem with old versions of SYSLINUX.] Signed-off-by: Jens Rottmann <JRottmann at LiPPERT-AT. de> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* | x86/paravirt: revert exports to restore old behaviourJeremy Fitzhardinge2007-11-291-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Subdividing the paravirt_ops structure caused a regression in certain non-GPL modules which try to use mmu_ops and cpu_ops. This restores the old behaviour, and makes it consistent with the non-CONFIG_PARAVIRT case. Takashi Iwai <tiwai@suse.de> adds: > I took at this problem (as I have an nvidia card on one of my > workstations), and found out that the following suffer from > EXPORT_SYMBOL_GPL changes: > > * local_disable_irq(), local_irq_save*(), etc. > * MSR-related macros like rdmsr(), wrmsr(), read_cr0(), etc. > wbinvd(), too. > * pmd_val(), pgd_val(), etc are all involved with pv_mm_ops. > pmd_large() and pmd_bad() is also indirectly involved. > __flush_tlb() and friends suffer, too. Christoph Hellwig objects to this patch on the grounds that modules shouldn't be using these operations anyway. I don't think this is a particularly good reason to reject the patch, for several reasons: 1. These operations are still available to modules when not using CONFIG_PARAVIRT, since they are implicitly exported as inline functions via the kernel headers. Exporting the same functionality as GPL-only symbols just adds a gratuitious difference between CONFIG_PARAVIRT and non-CONFIG_PARAVIRT configurations. If we really think these operations are not for module use (or non-GPL module use), then we should solve the problem in a general way. 2. It's a regression from previous kernels, which would work these modules even with CONFIG_PARAVIRT enabled. 3. The operations in question seem pretty reasonable for modules to use. The control registers/MSRs can be accessed directly anyway, so there's no benefit in preventing modules from using standard interfaces. And it seems reasonable to allow a graphics driver to create its own mappings if it wants. Therefore, I think this patch should go in for 2.6.24. If people really think that these operations should not be available to modules, then we can address that separately.

* | FRV: arrange things such that BRA can reach from the trap tableDavid Howells2007-11-294-15/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Arrange the sections in the FRV arch so that a BRA instruction with a 16-bit displacement can always reach from the trap table to entry.S, tlb-miss.S and break.S. The problem otherwise is that the linker can insert sufficient code between the slots in the trap table and the targets of the branch instructions in those slots that the displacement field in the instruction isn't sufficiently large. This is because the branch targets were in the .text section along with most of the other code in the kernel.

* | uml: fix !NO_HZ busy-loopJeff Dike2007-11-291-3/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With NO_HZ disabled, the UML idle loop effectively becomes a busy loop, as it will sleep for no time. The cause was forgetting to restart the tick after waking up from sleep. It was disabled before sleeping, and the remaining time used as the interval to sleep. So, the tick needs to be restarted when nanosleep finishes. This is done by introducing after_sleep_interval, which is empty in the NO_HZ case, but which sets the tick starting in the !NO_HZ case.

* | xen: mask _PAGE_PCD from ptesJeremy Fitzhardinge2007-11-291-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | _PAGE_PCD maps a page with caching disabled, which is typically used for mapping harware registers. Xen never allows it to be set on a mapping, and unprivileged guests never need it since they can't see the real underlying hardware. However, some uncached mappings are made early when probing the (non-existent) APIC, and its OK to mask off the PCD flag in these cases. This became necessary because Xen started checking for this bit, rather than silently masking it off.

* | Fix boot problem with iSeries lacking hugepage supportMel Gorman2007-11-291-0/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | Ordinarily the size of a pageblock is determined at compile-time based on the hugepage size. On PPC64, the hugepage size is determined at runtime based on what is supported by the machine. With legacy machines such as iSeries that do not support hugepages, HPAGE_SHIFT is 0. This results in pageblock_order being set to -PAGE_SHIFT and a crash results shortly afterwards. This patch adds a function to select a sensible value for pageblock order by default when HUGETLB_PAGE_SIZE_VARIABLE is set. It checks that HPAGE_SHIFT is a sensible value before using the hugepage size; if it is not MAX_ORDER-1 is used. This is a fix for 2.6.24. Credit goes to Stephen Rothwell for identifying the bug and testing candidate patches. Additional credit goes to Andy Whitcroft for spotting a problem with respects to IA-64 before releasing. Additional credit to David Gibson for testing with the libhugetlbfs test suite.

| * x86: printk kernel version in WARN_ON and other dump_stack usersArjan van de Ven2007-11-262-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | today, all oopses contain a version number of the kernel, which is nice because the people who actually do bother to read the oops get this vital bit of information always without having to ask the reporter in another round trip. However, WARN_ON() and many other dump_stack() users right now lack this information; the patch below adds this. This information is essential for getting people to use their time effectively when looking at these things; in addition, it's essential for tools that try to collect statistics about defects. Please consider, since its so simple and important for long term kernel quality processes. The code is identical between 32/64 bit; a lot of this code should be unified over time, the patch keeps the identical-ness intact.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revert this patch: move the init sections to the end of memory, so that after they are free, run time memory is all continugous - this should help decrease memory fragementation. When doing this, we also pack some of the other sections a little closer together, to make sure we don't waste memory. To make this happen, we need to rename the .data.init_task section to .init_task.data, so it doesn't get picked up by the linker script glob. Since it causes the kernel not to boot up with mtd filesystems. Signed-off-by: Bernd Schmidt <bernd.schmidt@analog.com> Signed-off-by: Bryan Wu <bryan.wu@analog.com>
