[PATCH] arm64: Do not include linux/uaccess.h from assembler files

[Guenter Roeck]

Including linux/uaccess.h from assembler files in arm64 builds results
in the following build errors.

In file included from arm64/include/asm/asm-offsets.h:1:0,
                 from arch/arm64/include/asm/assembler.h:26,
		 from arch/arm64/include/asm/alternative.h:68,
		 from arch/arm64/kernel/entry.S

include/linux/sched/prio.h: Assembler messages:
include/linux/sched/prio.h:47: Error:
	unknown mnemonic `static' --
		`static inline long nice_to_rlimit(long nice)'
build/include/linux/sched/prio.h:48: Error:
	junk at end of line, first unrecognized character is `{'

[and many more]

If asm/uaccess.h is not included, many of the affected files fail to build
with errors such as the following.

arch/arm64/lib/copy_to_user.S: Assembler messages:
arch/arm64/lib/copy_to_user.S:66: Error:
	unknown mnemonic `uaccess_enable_not_uao' --
		`uaccess_enable_not_uao x3,x4'
arch/arm64/lib/copy_template.S:71: Error:
	unknown mnemonic `uao_user_alternative' --
		`uao_user_alternative 9998f,strb,st trb,tmp1w,dst,#1'

Either drop the include if unnecessary or, if needed, replace with
asm/uaccess.h.

Fixes: 7c0f6ba682b9 ("Replace <asm/uaccess.h> with <linux/uaccess.h> globally")
