This reverts commit c9ccf30d. Entering the kernel at startup_32 without passing our real mode data in %esi, and without guaranteeing that physical and virtual addresses are identity mapped makes head.S impossible to maintain. The only user of this infrastructure is lguest which is not merged so nothing we currently support will break by removing this over designed nightmare, and only the pending lguest patches will be affected. The pending Xen patches have a different entry point that they use. We are currently discussing what Xen and lguest need to do to boot the kernel in a more normal fashion so using startup_32 in this weird manner is clearly not their long term direction. So let's remove this code in head.S before it causes brain damage to people trying to maintain head.S Cc: Chris Wright <chrisw@sous-sol.org> Cc: Andi Kleen <ak@suse.de> Cc: Jeremy Fitzhardinge <jeremy@goop.org> Cc: Zachary Amsden <zach@vmware.com> CC: H.

Commit 2f4dfe20 moved the definition of hard_smp_processor_id() for the UP case from include/linux/smp.h to include/asm/smp.h. However, include/linux/smp.h only includes include/asm/smp.h in the SMP case, so code that wants to use hard_smp_processor_id() has to include <asm/smp.h> explicitly to be sure of getting the definition.

If CONFIG_BLK_DEV_INITRD is not defined the prop variable in early_init_dt_scan_chosen() is unused, causing a compiler warning. So split the initrd logic into a separate function, allowing us to declare prop only when we need it. Built for both cases and booted with an initrd.

This adds the necessary support to hpte_decode() to handle 1TB segments and 16GB pages, and removes an uninitialized value warning on avpn. We don't have any code to generate HPTEs for 1TB segments or 16GB pages yet, so this is mostly for completeness, and to fix the warning.

My patch "Cope with PCI host bridge I/O window not starting at 0" introduced a bug in the calculation of the virtual addresses for the I/O windows of PCI host bridges other than the first, because it didn't account for the fact that hose->io_resource gets offset so that it reflects the range of global I/O port numbers assigned to the bridge. This fixes it and simplifies get_bus_io_range() in the process. Signed-off-by: NPaul Mackerras <paulus@samba.org>

Celleb has multiple PCI host bridges (phbs). Previous boot logic gives non-overlapped bus IDs between PCI host bridges so you can identify PHB by bus ID. But newer boot logic gives same bus ID between PHBs (it gives bus ID 0 as root bus.) So we have to set 'phb->buid' as non-zero.

The rheap allocation functions return a pointer, but the actual value is based on how the heap was initialized, and so it can be anything, e.g. an offset into a buffer. A ulong is a better representation of the value returned by the allocation functions. This patch changes all of the relevant rheap functions to use a unsigned long integers instead of a pointer. In case of an error, the value returned is a negative error code that has been cast to an unsigned long. The caller can use the IS_ERR_VALUE() macro to check for this. All code which calls the rheap functions is updated accordingly. Macros IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE(). Also added error checking to rh_attach_region().

This finally renames the thread_info field in task structure to stack, so that the assumptions about this field are gone and archs have more freedom about placing the thread_info structure. Nonbroken archs which have a proper thread pointer can do the access to both current thread and task structure via a single pointer. It'll allow for a few more cleanups of the fork code, from which e.g. ia64 could benefit.
