EFI_DISK_IO_PROTOCOL is a simplified interface to block devices. Use this
instead of EFI_BLOCK_IO_PROTOCOL for accessing block devices to simplify
the code -- we no longer need to worry about the underlying media's block
I/O size and alignment requirements.
This test lived together with a few unrelated tests in moderrs.mk, it is
better placed in varmod-subst-regex.mk though.
While here, extend, document and explain the test since its purpose was
not obvious from reading the code alone.
It is not always an error for a subexpression to have not matched,
since the regex library can/does not convey how many matches are
expected, only report an error if opts.strict (-dL)

interpreted as "showregs", whcih would print the values of the registers
at each instruction. Unfortunately, this was fundamentally broken because
the saved registers accessible to DDB are only valid for the faulting
insn that got us into DDB, and not arbitrary isns that can be examined
from within DDB.
For the possible operators that occur in message 324, print_tnode is
equivalent to op_name, and the latter is simpler.
When the function print_node was added to the code base, it had another
use in init.c, for understanding how initialization works in lint. That
code has since been rewritten completely, therefore print_tnode is no
longer needed. For debugging, display_expression is the better choice
since it has multi-line output and does not suffer from a fixed-length
buffer.
No functional change.
The name v_unsigned suggested that the value would be interpreted as
unsigned, which was wrong. Whether a value is signed or unsigned is
decided by v_tspec instead.
Revert the previous commit for boolen constants since their value is
already interpreted as unsigned, and there is no need for any warning
about differences between traditional C and ANSI C since the _Bool type
has only been added ten years later in C99.
The code for printing a tree node was also confused by this struct
member, even with its old name v_ansiu. That code will be fixed in a
follow-up commit.
No functional change.
In strict bool mode, bool is not an arithmetic type anyway, therefore it
doesn't matter whether the type is signed or unsigned.
C99 6.2.5p6 defines _Bool as one of the "standard unsigned integer
types", so making the constants unsigned is more accurate.

access. For slow media (like ISO image redirection on Lenovo HR330A BMC)
this is needed because otherwise the default watchdog timeout fires before
we can finish loading the kernel from install media.
When lint was written in 1995, traditional C was still nearby since C90
had been around for only 5 years. 26 years later, almost all code
adheres to C90 or even C99 or C11, therefore "C90 or later" can safely
be assumed as the default.
No functional change.
Before C99, these tokens were only used in member access expressions.
C99 reused the operator '.' in initializations of structs and unions.
Let the grammar check for syntax errors instead of writing custom code.

the PCI interrupt initialization routine. Instead, register said routines
by systype in a link set, and look them up and invoke them in a new function
alpha_pci_intr_init().
