Yannick found that video does not work with 2.6.34. The cause of this bug was that the BIOS had assigned the wrong range to the PCI bridge above the video device. Before 2.6.34 the kernel would have shrunk the size of the bridge window, but since d65245c3 PCI: don't shrink bridge resources the kernel will avoid shrinking BIOS ranges. So zero out the old range if we fail to claim it at boot time; this will cause us to allocate a new range at startup, restoring the 2.6.34 behavior. Fixes regression https://bugzilla.kernel.org/show_bug.cgi?id=16009.

Reinstate the null behaviour that the in-kernel gdbstub had for the GDB remote protocol 'p' command (retrieve a single register value) prior to commit 7ca8b9c0 ("frv: extend gdbstub to support more features of gdb"). Before that, the 'p' command just returned an empty reply, which causes gdb to then go and use the 'g' command. However, since that commit, the 'p' command returns an error string, which causes gdb to abort its connection to the target. Not all gdb versions are affected, some use try 'g' first, and if that works, don't bother with 'p', and so don't see the error.

If cr0.wp=0, we have to allow the guest kernel access to a page with pte.w=0. We do that by setting spte.w=1, since the host cr0.wp must remain set so the host can write protect pages. Once we allow write access, we must remove user access otherwise we mistakenly allow the user to write the page.

Always invalidate spte and flush TLBs when changing page size, to make sure different sized translations for the same address are never cached in a CPU's TLB. Currently the only case where this occurs is when a non-leaf spte pointer is overwritten by a leaf, large spte entry. This can happen after dirty logging is disabled on a memslot, for example.

The commit "asm-generic: add NEED_SG_DMA_LENGTH to define sg_dma_len()" 18e98307 broke microblaze compilation. dma_direct_map_sg() sets sg->dma_length, however microblaze doesn't set NEED_SG_DMA_LENGTH so scatterlist strcutres doesn't include dma_length. sg->dma_length is always equal to sg->length on microblaze. So we don't need to set set dma_length, that is, microblaze can simply use sg->length. Signed-off-by: NFUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: NMichal Simek <monstr@monstr.eu>

When functions incoming parameters are not in input operands list gcc 4.5 does not load the parameters into registers before calling this function but the inline assembly assumes valid addresses inside this function. This breaks the code because r0 and r1 are invalid when execution enters v4wb_copy_user_page () Also the constant needs to be used as third input operand so account for that as well.

When CONFIG_DEBUG_HIGHMEM is used, the fixmap entry used for a highmem page by kmap_atomic() is always cleared by kunmap_atomic(). This helps find bad usages such as dereferences after the unmap, or overflow into the adjacent fixmap areas. But this debugging aid is completely bypassed when a kmap for the same page already exists as the kmap is reused instead. ON VIVT systems we have no choice but to reuse that kmap due to cache coherency issues, but on non VIVT systems we should always force the fixmap usage when debugging is active.

The core suspend/resume code is run from stop_machine on CPU0 but parts of the suspend/resume machinery (including xen_arch_resume) are run on whichever CPU happened to schedule the xenwatch kernel thread. As part of the non-core resume code xen_arch_resume is called in order to restart the timer tick on non-boot processors. The boot processor itself is taken care of by core timekeeping code. xen_arch_resume uses smp_call_function which does not call the given function on the current processor. This means that we can end up with one CPU not receiving timer ticks if the xenwatch thread happened to be scheduled on CPU > 0. Use on_each_cpu instead of smp_call_function to ensure the timer tick is resumed everywhere.
