Building kernels before linux-4.7 with gcc-8 results in many build failures
when gcc triggers a check that was meant to catch broken compilers:
/tmp/ccCGMQmS.s:648: Error: .err encountered
According to the discussion in the gcc bugzilla, a local "register
asm()" variable is still supposed to be the correct way to force an
inline assembly to use a particular register, but marking it 'const'
lets the compiler do optimizations that break that, i.e the compiler is
free to treat the variable as either 'const' or 'register' in that case.
Upstream commit 9f73bd8bb445 ("ARM: uaccess: remove put_user() code
duplication") fixed this problem in linux-4.8 as part of a larger change,
but seems a little too big to be backported to 4.4.
Let's take the simplest fix and change only the one broken line in the
same way as newer kernels.

While MXM3 pin 37 aka WAKE1_MICO is pulled up with 4.7 K on the Apalis
Evaluation board and 100 K on the Ixora carrier board a custom carrier
board may leave it floating which may cause an unintended high interrupt
load on the default wake-up key with which may cause a lower CPU

While working on the 32-bit ARM port of UEFI, I noticed a strange
corruption in the kernel log. The following snprintf() statement
(in drivers/firmware/efi/efi.c:efi_md_typeattr_format())
snprintf(pos, size, "|%3s|%2s|%2s|%2s|%3s|%2s|%2s|%2s|%2s]",
was producing the following output in the log:
| | | | | |WB|WT|WC|UC]
| | | | | |WB|WT|WC|UC]
| | | | | |WB|WT|WC|UC]
|RUN| | | | |WB|WT|WC|UC]*
|RUN| | | | |WB|WT|WC|UC]*
| | | | | |WB|WT|WC|UC]
|RUN| | | | |WB|WT|WC|UC]*
| | | | | |WB|WT|WC|UC]
|RUN| | | | | | | |UC]
|RUN| | | | | | | |UC]
As it turns out, this is caused by incorrect code being emitted for
the string() function in lib/vsprintf.c. The following code
if (!(spec.flags & LEFT)) {
while (len < spec.field_width--) {
if (buf < end)
*buf = ' ';
++buf;
}
}
for (i = 0; i < len; ++i) {
if (buf < end)
*buf = *s;
++buf; ++s;
}
while (len < spec.field_width--) {
if (buf < end)
*buf = ' ';
++buf;
}
when called with len == 0, triggers an issue in the GCC SRA optimization
pass (Scalar Replacement of Aggregates), which handles promotion of signed
struct members incorrectly. This is a known but as yet unresolved issue.
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65932). In this particular
case, it is causing the second while loop to be executed erroneously a
single time, causing the additional space characters to be printed.
So disable the optimization by passing -fno-ipa-sra.
