* ARM: pgtable: introduce pteval_t to represent a pte valueRussell King2010-11-265-25/+28

* ARM: pgtable: directly pass pgd/pmd/pte to their error functionsRussell King2010-11-262-12/+12

* ARM: improve compiler's ability to optimize page tablesRussell King2010-11-211-0/+3
| | | | | | | | | | Allow the compiler to better optimize the page table walking code by avoiding over-complex pmd_addr_end() calculations. These calculations prevent the compiler spotting that we'll never iterate over the PMD table, causing it to create double nested loops where a single loop will do.

| * KVM: VMX: Fix host userspace gsbase corruptionAvi Kivity2010-11-171-8/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We now use load_gs_index() to load gs safely; unfortunately this also changes MSR_KERNEL_GS_BASE, which we managed separately. This resulted in confusion and breakage running 32-bit host userspace on a 64-bit kernel. Fix by - saving guest MSR_KERNEL_GS_BASE before we we reload the host's gs - doing the host save/load unconditionally, instead of only when in guest long mode Things can be cleaned up further, but this is the minmal fix for now.

| | | | | | | | | | | | | | | | | | | | | | If fs or gs refer to the ldt, they must be reloaded after the ldt. Reorder the code to that effect.

The patch below presents a simple SCSI host lock push-down as an equivalent transformation. No locking or other behavior should change with this patch. All existing bugs and locking orders are preserved. Additionally, add one parameter to queuecommand, struct Scsi_Host * and remove one parameter from queuecommand, void (*done)(struct scsi_cmnd *) Scsi_Host* is a convenient pointer that most host drivers need anyway, and 'done' is redundant to struct scsi_cmnd->scsi_done. Minimal code disturbance was attempted with this change. Most drivers needed only two one-line modifications for their host lock push-down.

This patch coalesces any host bridge windows that overlap. For the example above, the result is this single window: pci_root PNP0A03:00: host bridge window [mem 0xafffffff-0xffffffff] This fixes a 2.6.34 regression.
