2009-09-22mm: replace various uses of num_physpages by totalram_pagesJan Beulich
Sizing of memory allocations shouldn't depend on the number of physical pages found in a system, as that generally includes (perhaps a huge amount of) non-RAM pages. The amount of what actually is usable as storage should instead be used as a basis here. Some of the calculations (i.e. those not intending to use high memory) should likely even use (totalram_pages - totalhigh_pages).

2009-06-15parisc: remove driver_data direct access of struct deviceGreg Kroah-Hartman
In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions.

2007-02-12[PATCH] mark struct file_operations const 5Arjan van de Ven

This means "DMA Read returns" can bypass "MMIO Writes". Violating the PCI specs in this case improves outbound DMA "flows" and is currently not required by any drivers. This is NOT a new behavior.

Signed-off-by: Grant Grundler <grundler@parisc-linux.org> 2.6.14-rc2-pa2 - make SBA more anal about invalidating pdir entries Previous code cleared the valid flag a pdir entry but it did NOT guarantee this change was visible to the PDIR before writing the PCOM register. Ie the SBA could pick up a stale entry if the write happened to hit the SBA before the cacheline was flushed from the cache. Long term, I think I want to make this a compile time flag. Developement tree should enable anal pdir checking by default and Debian can disable it with either a CONFIG option or one-line patch. fdc/sync options can only negatively affect performance though I haven't measure how much yet. If someone can run netperf TCP_RR across gige and compare -pa1 and -pa2, that would be sufficient. Cleaned up the use of "fdc" to make sure it's using "kernel" space id (specify sr0 but maps to sr4-7). It seems a bit fragile to assume "sr1" gets loaded with KERNEL_SPACE which is how the code works today. Tested on 32 and 64-bit SMP kernels on j6k.

This is bad since IOMMU can only talk to the first 1GB at most. Kudos to jejb for quickly spotting that bug. o jejb also noted SBA should *always* reject DMA masks > 32-bits since DMA-mapping.txt indicates caller should try again with 32-bits. o off-by-one error when comparing the mask to IOVA space size.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
