alpha: macro whitespace fixes

2015-01-13T13:23:49+00:00

While working on arch/alpha/include/asm/uaccess.h, I noticed
that some macros within this header are made harder to read because they
violate a coding style rule: space is missing after comma.

Fix it up.

alpha/uaccess: fix sparse errors

2015-01-13T13:23:00+00:00

virtio wants to read bitwise types from userspace using get_user.  At the
moment this triggers sparse errors, since the value is passed through an
integer.

Fix that up using __force.

alpha: Use new generic strncpy_from_user() and strnlen_user()

2012-08-19T15:41:18+00:00

Similar to x86/sparc/powerpc implementations except:
1) we implement an extremely efficient has_zero()/find_zero()
   sequence with both prep_zero_mask() and create_zero_mask()
   no-operations.
2) Our output from prep_zero_mask() differs in that only the
   lowest eight bits are used to represent the zero bytes
   nevertheless it can be safely ORed with other similar masks
   from prep_zero_mask() and forms input to create_zero_mask(),
   the two fundamental properties prep_zero_mask() must satisfy.

Tests on EV67 and EV68 CPUs revealed that the generic code is
essentially as fast (to within 0.5% of CPU cycles) of the old
Alpha specific code for large quadword-aligned strings, despite
the 30% extra CPU instructions executed.  In contrast, the
generic code for unaligned strings is substantially slower (by
more than a factor of 3) than the old Alpha specific code.

alpha: exception table sorting

2009-05-02T22:36:10+00:00

Exception fixups for sections other than .text (like one in futex_init())
break the natural ordering of fixup entries, so sorting is required.

Without that the result of the exception table search depends on phase of
the moon.

alpha: fix macros

2009-04-01T15:59:15+00:00

When this macros isn't called with 'fixup', e.g.  with foo this will
incorectly expand to foo->foo.bits.errreg

alpha: move include/asm-alpha to arch/alpha/include/asm

2008-08-15T16:19:40+00:00

Sam Ravnborg did the build-test that the direct header file move works,
I'm just committing it.

This is a pure move:

	mkdir arch/alpha/include
	git mv include/asm-alpha arch/alpha/include/asm

with no other changes.
