commit c6ffe100 moved the flag that tracks if the dcache contents for a directory are complete to dentry. The problem is there are lots of places that use ceph_dir_{set,clear,test}_complete() while holding i_ceph_lock. but ceph_dir_{set,clear,test}_complete() may sleep because they call dput(). This patch basically reverts that commit. For ceph_d_prune(), it's called with both the dentry to prune and the parent dentry are locked. So it's safe to access the parent dentry's d_inode and clear I_COMPLETE flag.

The page alignment field for a request is currently set in ceph_osdc_build_request(). It's not needed at that point nor do either of its callers need that value assigned at any point before they call ceph_osdc_start_request(). So move that assignment into ceph_osdc_start_request().

The only remaining reason to pass the osd request to calc_layout() is to fill in its r_num_pages and r_page_alignment fields. Once it fills those in, it doesn't do anything more with them. We can therefore move those assignments into the caller, and get rid of the "req" parameter entirely. Note, however, that the only caller is ceph_osdc_new_request(), and that immediately overwrites those fields with values based on its passed-in page offset. So the assignment inside calc_layout() was redundant anyway.

The bio_seg field is used by the ceph messenger in iterating through a bio. It should never have a negative value, so make it an unsigned. (I contemplated making it unsigned short to match the struct bio definition, but it offered no benefit.) Change variables used to hold bio_seg values to all be unsigned as well.

If an invalid layout is provided to ceph_osdc_new_request(), its call to calc_layout() might return an error. At that point in the function we've already allocated an osd request structure, so we need to free it (drop a reference) in the event such an error occurs. The only other value calc_layout() will return is 0, so make that explicit in the successful case.

variable_is_present() accesses '__efivars' directly, but when called via gsmi_init() Michel reports observing the following crash, BUG: unable to handle kernel NULL pointer dereference at (null) IP: variable_is_present+0x55/0x170 Call Trace: register_efivars+0x106/0x370 gsmi_init+0x2ad/0x3da do_one_initcall+0x3f/0x170 The reason for the crash is that '__efivars' hasn't been initialised nor has it been registered with register_efivars() by the time the google EFI SMI driver runs. The gsmi code uses its own struct efivars, and therefore, a different variable list. Fix the above crash by passing the registered struct efivars to variable_is_present(), so that we traverse the correct list.

User applications running on SMP kernels have long suffered from instability and random segmentation faults. This patch improves the situation although there is more work to be done. One of the problems is the various routines in pgtable.h that update page table entries use different locking mechanisms, or no lock at all (set_pte_at). This change modifies the routines to all use the same lock pa_dbit_lock. This lock is used for dirty bit updates in the interruption code. The patch also purges the TLB entries associated with the PTE to ensure that inconsistent values are not used after the page table entry is updated. The UP and SMP code are now identical. The change also includes a minor update to the purge_tlb_entries function in cache.c to improve its efficiency.

CONFIG_MLONGCALLS was introduced in commit ec758f98 to overcome linker issues when linking huge linux kernels, e.g. with many modules linked in. But in the kernel module loader there is no support yet for the new relocation types, which is why modules built with -mlong-calls can't be loaded. Furthermore, for modules long calls are not really necessary, since we already use stub sections which resolve long distance calls. So, let's just disable this compiler option when compiling kernel modules. Signed-off-by: NHelge Deller <deller@gmx.de>

When targetting 32-bit processors, __put_user emits a pair of stw instructions for the 8-byte case. If the type of __val is a pointer, the marshalling code casts it to the wider integer type of u64, resulting in the following compiler warnings: kernel/signal.c: In function 'copy_siginfo_to_user': kernel/signal.c:2752:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] kernel/signal.c:2752:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] [...] This patch fixes the warnings by removing the marshalling code and using the correct output modifiers in the __put_{user,kernel}_asm64 macros so that GCC will allocate the right registers without the need to extract the two words explicitly.

We need to check the runtime sys_table for the EFI version the firmware specifies instead of just checking for a NULL QueryVariableInfo. Older implementations of EFI don't have QueryVariableInfo but the runtime is a smaller structure, so the pointer to it may be pointing off into garbage. This is apparently the case with several Apple firmwares that support EFI 1.10, and the current check causes them to no longer boot. Fix based on a suggestion from Matthew Garrett.
