#   ARM: 9393/1: mm: Use conditionals for CFI branches
# 
#   Commit 9385/2 introduced a few branches inside function
#   prototypes when using CFI in order to deal with the situation
#   where CFI inserts a few bytes of function information in front
#   of the symbol.
# 
#   This is not good for older CPUs where every cycle counts.
# 
#   Commit 9386/2 alleviated the situation a bit by using aliases
#   for the cache functions with identical signatures.
# 
#   This leaves the coherent cache flush functions
#   *_coherent_kern_range() with these branches to the corresponing
#   *_coherent_user_range() around, since their return type differ and
#   they therefore cannot be aliased.
# 
#   Solve this by a simple ifdef so at least we can use fallthroughs
#   when compiling without CFI enabled.

# 
#   This registers a breakpoint handler for the new breakpoint type
#   (0x03) inserted by LLVM CLANG for CFI breakpoints.
# 
#   If we are in permissive mode, just print a backtrace and continue.

# 
#   As you can see the LKDTM test fails, but I expect that this would be

# 
#   We are currently not implementing target and type for the CFI

# 
#   CPUs without breakpoint support cannot handle breakpoints naturally,
#   in these cases the permissive mode will not work, CFI will fall over

# 
#   Internal error: Oops - undefined instruction: 0 [#1] PREEMPT ARM

#   PC is at lkdtm_indirect_call+0x38/0x4c
#   LR is at lkdtm_CFI_FORWARD_PROTO+0x30/0x6c

#   This is reasonable I think: it's the best CFI can do to ascertain

#   ARM: 9390/2: lib: Annotate loop delay instructions for CFI
# 
#   When we annotate the loop delay code with SYM_TYPED_FUNC_START()
#   a function prototype signature will be emitted into the object
#   file above each site called from C, and the delay loop code is
#   using "fallthroughs" from the different assembly callbacks. This
#   will not work as the execution flow will run into the prototype
#   signatures.
# 
#   Rewrite the code to use explicit branches to the other code
#   segments and annotate the code using SYM_TYPED_FUNC_START().
# 
#   Tested on the ARM Versatile which uses the calibrated loop delay.

# 
#   ARM: 9389/2: mm: Define prototypes for all per-processor calls
# 
#   Each CPU type ("proc") has assembly calls for initializing and
#   setting up the MM context, idle and so forth.
# 
#   These calls have the C form of e.g.:
# 
#   void cpu_arm920_init(void);
# 
#   However this prototype is not really specified, instead it is
#   generated by the glue code in <asm/glue-proc.h> and the prototype
#   is implicit from the generic prototype defined in <asm/proc-fns.h>
#   such as cpu_proc_init() in this case. (This is a bit similar to
#   the "interface" or inheritance concept in other languages.)
# 
#   To be able to annotate these assembly calls for CFI, they all need
#   to have a proper C prototype per CPU call.
# 
#   Define these in a new C file that is only compiled when we use
#   CFI, and add __ADDRESSABLE() to each so the compiler knows that
#   these will be addressed (they are not explicitly called in C, they
#   are called by way of cpu_proc_init() etc).
# 
#   It is a bit of definitions, but we do not expect new ARM32 CPUs
#   to appear very much so it should be pretty static.

#   ARM: 9387/2: mm: Rewrite cacheflush vtables in CFI safe C
# 
#   Instead of defining all cache flush operations with an assembly
#   macro in proc-macros.S, provide an explicit struct cpu_cache_fns
#   for each CPU cache type in mm/cache.c.
# 
#   As a side effect from rewriting the vtables in C, we can
#   avoid the aliasing for the "louis" cache callback, instead we
#   can just assign the NN_flush_kern_cache_all() function to the
#   louis callback in the C vtable.
# 
#   As the louis cache callback is called explicitly (not through the
#   vtable) if we only have one type of cache support compiled in, we
#   need an ifdef quirk for this in the !MULTI_CACHE case.
# 
#   Feroceon and XScale have some dma mapping quirk, in this case we
#   can just define two structs and assign all but one callback to the
#   main implementation; since each of them invoked define_cache_functions
#   twice they require MULTI_CACHE by definition so the compiled-in
#   shortcut is not used on these variants.

#   ARM: 9386/2: mm: Use symbol alias for cache functions
# 
#   The cache functions to flush user cache (*_flush_user_cache_all)
#   are in many cases just a branch to the corresponfing userspace or
#   kernelspace function. These functions also have the same arguments.
# 
#   Simplify these by using SYM_FUNC_ALIAS() in all affected sites.
# 
#   The NOP cache has very many similar calls which are just returns,
#   but it would be confusing to use aliases here, so leave all the
#   explicit returns and drop a comment on why we are not using aliases.

#   and SYM_FUNC_END() so they also become CFI-safe.
# 
#   When we add SYM_TYPED_FUNC_START() to assembly calls, a function
#   prototype signature will be emitted into the object file at
#   (pc-4) at the call site, so that the KCFI runtime check can compare
#   this to the expected call. Example:
# 
#   8011ae38:       a540670c        .word   0xa540670c
# 
#   8011ae3c <v7_flush_icache_all>:
#   8011ae3c:       e3a00000        mov     r0, #0
#   8011ae40:       ee070f11        mcr     15, 0, r0, cr7, cr1, {0}
#   8011ae44:       e12fff1e        bx      lr
# 
#   This means no "fallthrough" code can enter a SYM_TYPED_FUNC_START()
#   call from above it: there will be a function prototype signature
#   there, so those are consistently converted to a branch or ret lr
#   depending on context.

#   ARM: 9384/2: mm: Make tlbflush routines CFI safe
# 
#   Instead of avoiding CFI entirely on the TLB flush helpers, reorganize
#   the code so that the CFI machinery can deal with it. The important
#   things to take into account are:
#   - functions in asm called indirectly from C need to be defined using
#     SYM_TYPED_FUNC_START()
#   - a reference to the asm function needs to be visible to the compiler,
#     in order to get it to emit the typeid symbol.
# 
#   The latter means that defining the cpu_tlb_fns structs is best done from
#   C code, so that the references in the static initializers will be
#   visible to the compiler.

#   ARM: 9358/2: Implement PAN for LPAE by TTBR0 page table walks disablement
# 
#   With LPAE enabled, privileged no-access cannot be enforced using CPU
#   domains as such feature is not available. This patch implements PAN
#   by disabling TTBR0 page table walks while in kernel mode.
# 
#   The ARM architecture allows page table walks to be split between TTBR0
#   and TTBR1. With LPAE enabled, the split is defined by a combination of
#   TTBCR T0SZ and T1SZ bits. Currently, an LPAE-enabled kernel uses TTBR0
#   for user addresses and TTBR1 for kernel addresses with the VMSPLIT_2G
#   and VMSPLIT_3G configurations. The main advantage for the 3:1 split is
#   that TTBR1 is reduced to 2 levels, so potentially faster TLB refill
#   (though usually the first level entries are already cached in the TLB).
# 
#   The PAN support on LPAE-enabled kernels uses TTBR0 when running in user
#   space or in kernel space during user access routines (TTBCR T0SZ and
#   T1SZ are both 0). When running user accesses are disabled in kernel
#   mode, TTBR0 page table walks are disabled by setting TTBCR.EPD0. TTBR1
#   is used for kernel accesses (including loadable modules; anything
#   covered by swapper_pg_dir) by reducing the TTBCR.T0SZ to the minimum
#   (2^(32-7) = 32MB). To avoid user accesses potentially hitting stale TLB
#   entries, the ASID is switched to 0 (reserved) by setting TTBCR.A1 and
#   using the ASID value in TTBR1. The difference from a non-PAN kernel is
#   that with the 3:1 memory split, TTBR1 always uses 3 levels of page
#   tables.
# 
#   As part of the change we are using preprocessor elif definied() clauses
#   so balance these clauses by converting relevant precedingt ifdef
#   clauses to if defined() clauses.

#   ARM: 9361/1: amba: store owner from modules with amba_driver_register()
# 
#   Modules registering driver with amba_driver_register() often forget to
#   set .owner field.  The field is used by some of other kernel parts for
#   reference counting (try_module_get()), so it is expected that drivers
#   will set it.
# 
#   Solve the problem by moving this task away from the drivers to the core
#   amba bus code, just like we did for platform_driver in
#   commit 9447057eaff8 ("platform_device: use a macro instead of
#   platform_driver_register").
