| * ARM: imx: Add wake functionality to GPIODinh Nguyen2010-10-261-0/+32
| | | | | | | | | | | | | | | | | | | | | | | | Add function definition for irq_chip.set_wake to enable GPIO to wake-up the system. This patch has been tested on a MX51 Babbage system that had suspend code implemented. The set_wake implementation is necessary for a GPIO to wake up a system from suspend.

As (the only user of MXC_INT_MMC_SDHC2) is only used on mx31 use the MX31 prefixed symbol to define its resources. Moreover to reduce further confusion mxcsdhc_device0 is fixed accordingly and the MXC prefixed symbols are removed.

We need to update the entires in both p2m_top_mfn and the mid_mfn pages which p2m_top_mfn refers to. In order to do this we need to keep track of the virtual addresses mapping the p2m_mid_mfn pages since we cannot rely on mfn_to_virt(p2m_top_mfn[idx]) since p2m_top_mfn[idx] will still contain the old MFN after a migration, which may now belong to another domain and hence have a different mapping in the m2p. Therefore add and maintain a third top level page, p2m_top_mfn_p[], which tracks the virtual addresses of the mfns contained in p2m_top_mfn[]. We also need to update the content of the p2m_mid_missing_mfn page on resume to refer to the page's new mfn. p2m_missing does not need updating since the migration process takes care of the leaf p2m pages for us.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an E820 region is entirely beyond mem_end, don't attempt to truncate it and add the truncated pages to extra_pages, as they will be negative. Also, make sure the extra memory region starts after all BIOS provided E820 regions (and in the case of RAM regions, post-clipping).

Linux doesn't use _PAGE_PAT for ptes, so the only difference in the first 4 entries is that Linux uses _PAGE_PWT for WC, whereas Xen (and default) use it for WT. xen_pte_val does the inverse conversion. We hard-code assumptions about Linux's current PAT layout, but a warning on the wrmsr to MSR_IA32_CR_PAT should point out any problems. If necessary we could go to a more general table-based conversion between Linux and Xen PAT entries. hugetlbfs poses a problem at the moment, the x86 architecture uses the same flag for _PAGE_PAT and _PAGE_PSE, which changes meaning depending on which pagetable level we're using. At the moment this should be OK so long as nobody tries to do a pte_val on a hugetlbfs pte. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If extra memory is very much larger than the base memory size then all of the base memory can be filled with structures reserved to describe the extra memory, leaving no space for anything else.

Count these pages, and add them to a new "extra memory" range. This range has an E820 RAM range to describe it - so the kernel will allocate page structures for it - but it is also marked reserved so that the kernel will not attempt to use it. The balloon driver can then add this range as a set of currently ballooned-out pages, which can be used to extend the domain beyond its original size.

This allows the domain builder to tell the domain to reserve space for more pages than those initially provided at domain-build time. It also allows the host to specify holes in the address space (for PCI-passthrough, for example).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building mfn parts of p2m structure, we rely on being able to use mfn_to_virt, which in turn requires kernel to be mapped into the linear area (which is distinct from the kernel image mapping on 64-bit).

The p2m structure contains mappings from the domain's pfns to system-wide mfns. The structure has 3 levels and two roots. The first root is for the domain's own use, and is linked with virtual addresses. The second is all mfn references, and is used by Xen on save/restore to allow it to update the p2m mapping for the domain. At boot, the domain builder provides a simple flat p2m array for all the initially present pages. We construct the two levels above that using the early_brk allocator. After early boot time, set_phys_to_machine() will allocate any missing levels using the normal kernel allocator (at GFP_KERNEL, so it must be called in a normal blocking context). Because the early_brk() API requires us to pre-reserve the maximum amount of memory we could allocate, there is still a CONFIG_XEN_MAX_DOMAIN_MEMORY config option, but its only negative side-effect is to increase the kernel's apparent bss size. However, since all unused brk memory is returned to the heap, there's no real downside to making it large. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>

| | * | | | acpi-cpufreq: fix a memleak when unloading driverZhang Rui2010-10-121-0/+1

Now we just use straight 32-bit arguments in COMPAT mode, thus requiring individual registers to be read/written with two syscalls. Of course this is uncommon, since usually all the registers are read or written at once. The restructuring applies to all the tile platforms, but is plausibly better than the original code in any case. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
