2008-05-20x86: use PTE_MASK rather than ad-hoc maskJeremy Fitzhardinge
Use ~PTE_MASK to extract the non-pfn parts of the pte (ie, the pte flags), rather than constructing an ad-hoc mask. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Tested-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-05-20x86: clarify use of _PAGE_CHG_MASKJeremy Fitzhardinge

2008-05-20x86: fix warning on 32-bit non-PAEJeremy Fitzhardinge
Fix the warning: include2/asm/pgtable.h: In function `pte_modify': include2/asm/pgtable.h:290: warning: left shift count >= width of type On 32-bit PAE the virtual and physical addresses are both 32-bits, so it ends up evaluating 1<<32. Do the shift as a 64-bit shift then cast to the appropriate size. This should all be done at compile time, and so have no effect on generated code.

2008-05-20x86: define PTE_MASK in a universally useful wayJeremy Fitzhardinge
Define PTE_MASK so that it contains a meaningful value for all x86 pagetable configurations. Previously it was defined as a "long" which means that it was too short to cover a 32-bit PAE pte entry. It is now defined as a pteval_t, which is an integer type long enough to contain a full pte (or pmd, pud, pgd). This fixes an Xorg crash on 32-bit x86 with PAE due to corruption of the NX bit in mprotect due to the incorrect type/value of PTE_MASK reported by Hugh Dickins: "Yes, thanks Jeremy: I've checked that each stage builds and runs X on my boxes here, x86_32 and x86_32+PAE and x86_64. (So even 1/8 is enough to fix the PAT pte_modify issue, though 2/8 then fixes compiler warnings.)"

2008-05-20HID: split Numlock emulation quirk from HID_QUIRK_APPLE_HAS_FN.Diego 'Flameeyes' Petteno
Since 2.6.25 the HID_QUIRK_APPLE_HAS_FN quirk is enabled even for non-laptop Apple keyboards of the Aluminium series. The USB version of these don't need Numlock emulation, like the laptop (and Aluminium Wireless) do, as they have a proper keypad. This patch splits the Numlock emulation for Apple keyboards in a different quirk flag, so that it can be enabled for all the keyboards but the Aluminium USB ones. If the Numlock emulation is enabled for Aluminium USB keyboards, the JKL and UIO keys become the numeric pad, and the rest of the keyboard is disabled, included the key used to disable Numlock. Additionally, these keyboard should not have a Numlock at all, as the Numlock key is instead replaced by the 'Clear' key as usual for Apple USB keyboards.

2008-05-20sparc64: Add global register dumping facility.David S. Miller
When a cpu really is stuck in the kernel, it can be often impossible to figure out which cpu is stuck where. The worst case is when the stuck cpu has interrupts disabled. Therefore, implement a global cpu state capture that uses SMP message interrupts which are not disabled by the normal IRQ enable/disable APIs of the kernel. As long as we can get a sysrq 'y' to the kernel, we can get a dump. Even if the console interrupt cpu is wedged, we can trigger it from userspace using /proc/sysrq-trigger The output is made compact so that this facility is more useful on high cpu count systems, which is where this facility will likely find itself the most useful :) Signed-off-by: David S.

I was hoping ATA_HORKAGE_NODMA | ATA_HORKAGE_SKIP_PM could keep it happy but no even this doesn't work under certain configurations and it's not like we can do anything useful with the cofig device anyway.

2008-05-19libata: increase PMP register access timeout to 3sTejun Heo
This timeout was set low because previously PMP register access was done via polling and register access timeouts could stack up. This is no longer the case. One timeout will make all following accesses fail immediately. In rare cases both marvell and SIMG PMPs need almost a second. Bump it to 3s. While at it, rename it to SATA_PMP_RW_TIMEOUT.

2008-05-19svcrdma: Simplify RDMA_READ deferral buffer managementTom Tucker
An NFS_WRITE requires a set of RDMA_READ requests to fetch the write data from the client. There are two principal pieces of data that need to be tracked: the list of pages that comprise the completed RPC and the SGE of dma mapped pages to refer to this list of pages. Previously this whole bit was managed as a linked list of contexts with the context containing the page list buried in this list. This patch simplifies this processing by not keeping a linked list, but rather only a pionter from the last submitted RDMA_READ's context to the context that maps the set of pages that describe the RPC. This significantly simplifies this code path. SGE contexts are cleaned up inline in the DTO path instead of at read completion time. Signed-off-by: Tom Tucker <tom@opengridcomputing.com>
