Stop the HPPFS filesystem from using iget() and read_inode(). Provide an hppfs_iget(), and call that instead of iget(). hppfs_iget() then uses iget_locked() directly and returns a proper error code instead of an inode in the event of an error. hppfs_fill_sb_common() returns any error incurred when getting the root inode instead of EINVAL. Note that the contents of hppfs_kern.c need to be examined: (*) The HPPFS inode retains a pointer to the proc dentry it is shadowing, but whilst it does appear to retain a reference to it, it doesn't appear to destroy the reference if the inode goes away. (*) hppfs_iget() should perhaps subsume init_inode() and hppfs_read_inode(). (*) It would appear that all hppfs inodes are the same inode because iget() was being called with inode number 0, which forms the lookup key.

This patchset is for the vmcoreinfo data. The vmcoreinfo data has the minimum debugging information only for dump filtering. makedumpfile (dump filtering command) gets it to distinguish unnecessary pages, and makedumpfile creates a small dumpfile. This patch: VMCOREINFO_SIZE() should be renamed VMCOREINFO_STRUCT_SIZE() since it's always returning the size of the struct with a given name. This change would allow VMCOREINFO_TYPEDEF_SIZE() to simply become VMCOREINFO_SIZE() since it need not be used exclusively for typedefs.

This patchset adds a flags variable to reserve_bootmem() and uses the BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions between crashkernel area and already used memory. This patch: Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE. If that flag is set, the function returns with -EBUSY if the memory already has been reserved in the past. This is to avoid conflicts. Because that code runs before SMP initialisation, there's no race condition inside reserve_bootmem_core().
