 	  Use optimized AES assembler routines for ARM platforms.
 
+	  On ARM processors without the Crypto Extensions, this is the
+	  fastest AES implementation for single blocks.  For multiple
+	  blocks, the NEON bit-sliced implementation is usually faster.
+
+	  This implementation may be vulnerable to cache timing attacks,

+ * ARM VMSAv8-64 defines an algorithm for finding the translation table
+ * descriptors in section D4.2.8 in ARM DDI 0487C.a.
+ *
+ * The algorithm defines the expectations on the translation table
+ * addresses for each level, based on PAGE_SIZE, entry level
+ * and the translation table size (T0SZ). The variable "x" in the
+ * algorithm determines the alignment of a table base address at a given
+ * level and thus determines the alignment of VTTBR:BADDR for stage2
+ * page table entry level.
+ * Since the number of bits resolved at the entry level could vary
+ * depending on the T0SZ, the value of "x" is defined based on a
+ * Magic constant for a given PAGE_SIZE and Entry Level. The
+ * intermediate levels must be always aligned to the PAGE_SIZE (i.e,
+ * x = PAGE_SHIFT).
+ *
+ * The value of "x" for entry level is calculated as :
+ *    x = Magic_N - T0SZ
+ *
+ * where Magic_N is an integer depending on the page size and the entry
+ * level of the page table as below:
+ *
+ *	--------------------------------------------
+ *	| Entry level		|  4K    16K   64K |
+ *	--------------------------------------------
+ *	| Level: 0 (4 levels)	| 28   |  -  |  -  |
+ *	--------------------------------------------
+ *	| Level: 1 (3 levels)	| 37   | 31  | 25  |
+ *	--------------------------------------------
+ *	| Level: 2 (2 levels)	| 46   | 42  | 38  |
+ *	--------------------------------------------
+ *	| Level: 3 (1 level)	| -    | 53  | 51  |
+ *	--------------------------------------------
+ *
+ * We have a magic formula for the Magic_N below:
+ *
+ *  Magic_N(PAGE_SIZE, Level) = 64 - ((PAGE_SHIFT - 3) * Number_of_levels)
+ *
+ * where Number_of_levels = (4 - Level). We are only interested in the
+ * value for Entry_Level for the stage2 page table.
+ *
+ * So, given that T0SZ = (64 - IPA_SHIFT), we can compute 'x' as follows:
+ *
+ *	x = (64 - ((PAGE_SHIFT - 3) * Number_of_levels)) - (64 - IPA_SHIFT)
+ *	  = IPA_SHIFT - ((PAGE_SHIFT - 3) * Number of levels)
+ *
+ * Here is one way to explain the Magic Formula:
+ *
+ *  x = log2(Size_of_Entry_Level_Table)
+ *
+ * Since, we can resolve (PAGE_SHIFT - 3) bits at each level, and another
+ * PAGE_SHIFT bits in the PTE, we have :
+ *
+ *  Bits_Entry_level = IPA_SHIFT - ((PAGE_SHIFT - 3) * (n - 1) + PAGE_SHIFT)
+ *		     = IPA_SHIFT - (PAGE_SHIFT - 3) * n - 3
+ *  where n = number of levels, and since each pointer is 8bytes, we have:
+ *
+ *  x = Bits_Entry_Level + 3
+ *    = IPA_SHIFT - (PAGE_SHIFT - 3) * n
+ *
+ * The only constraint here is that, we have to find the number of page table
+ * levels for a given IPA size (which we do, see stage2_pt_levels())

- *	TLB Management
- *	==============
+ *	TLB Invalidation
+ *	================
  *
- *	The TLB specific code is expected to perform whatever tests it needs
- *	to determine if it should invalidate the TLB for each call.  Start
- *	addresses are inclusive and end addresses are exclusive; it is safe to
- *	round these addresses down.
+ * 	This header file implements the low-level TLB invalidation routines
+ *	(sometimes referred to as "flushing" in the kernel) for arm64.
+ *
+ *	Every invalidation operation uses the following template:
+ *
+ *	DSB ISHST	// Ensure prior page-table updates have completed
+ *	TLBI ...	// Invalidate the TLB
+ *	DSB ISH		// Ensure the TLB invalidation has completed
+ *      if (invalidated kernel mappings)
+ *		ISB	// Discard any instructions fetched from the old mapping
  *
- *	flush_tlb_all()
  *
- *		Invalidate the entire TLB.
+ *	The following functions form part of the "core" TLB invalidation API,
+ *	as documented in Documentation/core-api/cachetlb.rst:
+ *
+ *	flush_tlb_all()
+ *		Invalidate the entire TLB (kernel + user) on all CPUs
  *
  *	flush_tlb_mm(mm)
+ *		Invalidate an entire user address space on all CPUs.
+ *		The 'mm' argument identifies the ASID to invalidate.
+ *
+ *	flush_tlb_range(vma, start, end)
+ *		Invalidate the virtual-address range '[start, end)' on all
+ *		CPUs for the user address space corresponding to 'vma->mm'.
+ *		Note that this operation also invalidates any walk-cache
+ *		entries associated with translations for the specified address
+ *		range.
  *
- *		Invalidate all TLB entries in a particular address space.
- *		- mm	- mm_struct describing address space
+ *	flush_tlb_kernel_range(start, end)
+ *		Same as flush_tlb_range(..., start, end), but applies to
+ * 		kernel mappings rather than a particular user address space.
+ *		Whilst not explicitly documented, this function is used when
+ *		unmapping pages from vmalloc/io space.
  *
- *	flush_tlb_range(mm,start,end)
+ *	flush_tlb_page(vma, addr)
+ *		Invalidate a single user mapping for address 'addr' in the
+ *		address space corresponding to 'vma->mm'.  Note that this
+ *		operation only invalidates a single, last-level page-table
+ *		entry and therefore does not affect any walk-caches.
  *
- *		Invalidate a range of TLB entries in the specified address
- *		space.
- *		- mm	- mm_struct describing address space
- *		- start - start address (may not be aligned)
- *		- end	- end address (exclusive, may not be aligned)
  *
- *	flush_tlb_page(vaddr,vma)
+ *	Next, we have some undocumented invalidation routines that you probably
+ *	don't want to call unless you know what you're doing:
  *
- *		Invalidate the specified page in the specified address range.
- *		- vaddr - virtual address (may not be aligned)
- *		- vma	- vma_struct describing address range
+ *	local_flush_tlb_all()
+ *		Same as flush_tlb_all(), but only applies to the calling CPU.
  *
- *	flush_kern_tlb_page(kaddr)
+ *	__flush_tlb_kernel_pgtable(addr)
+ *		Invalidate a single kernel mapping for address 'addr' on all
+ *		CPUs, ensuring that any walk-cache entries associated with the
+ *		translation are also invalidated.
  *
- *		Invalidate the TLB entry for the specified page.  The address
- *		will be in the kernels virtual memory space.  Current uses
- *		only require the D-TLB to be invalidated.
- *		- kaddr - Kernel virtual memory address
+ *	__flush_tlb_range(vma, start, end, stride, last_level)
+ *		Invalidate the virtual-address range '[start, end)' on all
+ *		CPUs for the user address space corresponding to 'vma->mm'.
+ *		The invalidation operations are issued at a granularity
+ *		determined by 'stride' and only affect any walk-cache entries
+ *		if 'last_level' is equal to false.
+ *
+ *
+ *	Finally, take a look at asm/tlb.h to see how tlb_flush() is implemented
+ *	on top of these routines, since that is our interface to the mmu_gather
+ *	API as used by munmap() and friends.

-	# This function encrypts eight consecutive ChaCha20 blocks by loading
-	# the state matrix in AVX registers eight times. As we need some
-	# scratch registers, we save the first four registers on the stack. The
-	# algorithm performs each operation on the corresponding word of each
-	# state matrix, hence requires no word shuffling. For final XORing step
-	# we transpose the matrix by interleaving 32-, 64- and then 128-bit
-	# words, which allows us to do XOR in AVX registers. 8/16-bit word
-	# rotation is done with the slightly better performing byte shuffling,
-	# 7/12-bit word rotation uses traditional shift+OR.

-#	STRUCT job_aes2
-#	RES_Q	.plaintext,	1
-#	RES_Q	.ciphertext,	1
-#	RES_DQ	.IV,		1
-#	RES_B	.nested,	_JOB_AES_SIZE, _JOB_AES_ALIGN

-#				...
-#	ENDSTRUCT
-#	# Following only needed if nesting
-#	%assign job_aes2_size	_FIELD_OFFSET
-#	%assign job_aes2_align	_STRUCT_ALIGN
-#
-# RES_* macros take a name, a count and an optional alignment.
-# The count in in terms of the base size of the macro, and the
-# default alignment is the base size.
-# The macros are:
-# Macro    Base size
-# RES_B	    1
-# RES_W	    2
-# RES_D     4
-# RES_Q     8
-# RES_DQ   16
-# RES_Y    32
-# RES_Z    64
-#
-# RES_U defines a union. It's arguments are a name and two or more
-# pairs of "size, alignment"
-#
-# The two assigns are only needed if this structure is being nested
-# within another. Even if the assigns are not done, one can still use
-# STRUCT_NAME_size as the size of the structure.
-#
-# Note that for nesting, you still need to assign to STRUCT_NAME_size.
-#
-# The differences between this and using "struc" directly are that each
-# type is implicitly aligned to its natural length (although this can be
-# over-ridden with an explicit third parameter), and that the structure
-# is padded at the end to its overall alignment.

-#	STRUCT job_aes2
-#	RES_Q	.plaintext,	1
-#	RES_Q	.ciphertext, 	1
-#	RES_DQ	.IV,		1
-#	RES_B	.nested,	_JOB_AES_SIZE, _JOB_AES_ALIGN
-#	RES_U	.union,		size1, align1, \
-#				size2, align2, \
-#				...
-#	ENDSTRUCT
-#	# Following only needed if nesting
-#	%assign job_aes2_size	_FIELD_OFFSET
-#	%assign job_aes2_align	_STRUCT_ALIGN
-#
-# RES_* macros take a name, a count and an optional alignment.
-# The count in in terms of the base size of the macro, and the
-# default alignment is the base size.
-# The macros are:
-# Macro    Base size
-# RES_B	    1
-# RES_W	    2
-# RES_D     4
-# RES_Q     8
-# RES_DQ   16
-# RES_Y    32
-# RES_Z    64
-#
-# RES_U defines a union. It's arguments are a name and two or more
-# pairs of "size, alignment"
-#
-# The two assigns are only needed if this structure is being nested
-# within another. Even if the assigns are not done, one can still use
-# STRUCT_NAME_size as the size of the structure.
-#
-# Note that for nesting, you still need to assign to STRUCT_NAME_size.
-#
-# The differences between this and using "struc" directly are that each
-# type is implicitly aligned to its natural length (although this can be
-# over-ridden with an explicit third parameter), and that the structure
-# is padded at the end to its overall alignment.

-#       RES_Q   .ciphertext,    1

-#       %assign job_aes2_size   _FIELD_OFFSET

-#
-# RES_* macros take a name, a count and an optional alignment.
-# The count in in terms of the base size of the macro, and the
-# default alignment is the base size.
-# The macros are:
-# Macro    Base size
-# RES_B     1
-# RES_W     2
-# RES_D     4
-# RES_Q     8
-# RES_DQ   16
-# RES_Y    32
-# RES_Z    64
-#
-# RES_U defines a union. It's arguments are a name and two or more
-# pairs of "size, alignment"
-#
-# The two assigns are only needed if this structure is being nested
-# within another. Even if the assigns are not done, one can still use
-# STRUCT_NAME_size as the size of the structure.
-#
-# Note that for nesting, you still need to assign to STRUCT_NAME_size.
-#
-# The differences between this and using "struc" directly are that each
-# type is implicitly aligned to its natural length (although this can be
-# over-ridden with an explicit third parameter), and that the structure
-# is padded at the end to its overall alignment.

+ * @sym:		Name of the generated entry point
+ * @do_sym: 		C function to be called
+ * @has_error_code: 	True if this IDT vector has an error code on the stack
+ * @paranoid: 		non-zero means that this vector may be invoked from
+ *			kernel mode with user GSBASE and/or user CR3.
+ *			2 is special -- see below.
+ * @shift_ist:		Set to an IST index if entries from kernel mode should
+ *             		decrement the IST stack so that nested entries get a
+ *			fresh stack.  (This is for #DB, which has a nasty habit
+ *             		of recursing.)
+ *
+ * idtentry generates an IDT stub that sets up a usable kernel context,
+ * creates struct pt_regs, and calls @do_sym.  The stub has the following
+ * special behaviors:
+ *
+ * On an entry from user mode, the stub switches from the trampoline or
+ * IST stack to the normal thread stack.  On an exit to user mode, the
+ * normal exit-to-usermode path is invoked.
+ *
+ * On an exit to kernel mode, if @paranoid == 0, we check for preemption,
+ * whereas we omit the preemption check if @paranoid != 0.  This is purely
+ * because the implementation is simpler this way.  The kernel only needs
+ * to check for asynchronous kernel preemption when IRQ handlers return.
+ *
+ * If @paranoid == 0, then the stub will handle IRET faults by pretending
+ * that the fault came from user mode.  It will handle gs_change faults by
+ * pretending that the fault happened with kernel GSBASE.  Since this handling
+ * is omitted for @paranoid != 0, the #GP, #SS, and #NP stubs must have
+ * @paranoid == 0.  This special handling will do the wrong thing for
+ * espfix-induced #DF on IRET, so #DF must not use @paranoid == 0.
+ *
+ * @paranoid == 2 is special: the stub will never switch stacks.  This is for
+ * #DF: if the thread stack is somehow unusable, we'll still get a useful OOPS.

+ * already blocked P-Unit accesses because it wants them blocked over multiple
+ * i2c-transfers, for e.g. read-modify-write of an I2C client register.

+ * iosf_mbi_block_punit_i2c_access_count_mutex this mutex is hold for the
+ * entire duration of the function.
+ *
+ * If access is not blocked yet, this function takes the following steps:
+ *
+ * 1) Some code sends request to the P-Unit which make it access the PMIC
+ *    I2C bus. Testing has shown that the P-Unit does not check its internal
+ *    PMIC bus semaphore for these requests. Callers of these requests call
+ *    iosf_mbi_punit_acquire()/_release() around their P-Unit accesses, these
+ *    functions lock/unlock the iosf_mbi_punit_mutex.
+ *    As the first step we lock the iosf_mbi_punit_mutex, to wait for any in
+ *    flight requests to finish and to block any new requests.
+ *
+ * 2) Some code makes such P-Unit requests from atomic contexts where it
+ *    cannot call iosf_mbi_punit_acquire() as that may sleep.
+ *    As the second step we call a notifier chain which allows any code
+ *    needing P-Unit resources from atomic context to acquire them before
+ *    we take control over the PMIC I2C bus.
+ *
+ * 3) When CPU cores enter C6 or C7 the P-Unit needs to talk to the PMIC
+ *    if this happens while the kernel itself is accessing the PMIC I2C bus
+ *    the SoC hangs.
+ *    As the third step we call pm_qos_update_request() to disallow the CPU
+ *    to enter C6 or C7.
+ *
+ * 4) The P-Unit has a PMIC bus semaphore which we can request to stop
+ *    autonomous P-Unit tasks from accessing the PMIC I2C bus while we hold it.
+ *    As the fourth and final step we request this semaphore and wait for our
