struct nand_chip now embeds an mtd device. Patch all drivers to make use

Section mismatches can now result in build failures.
As result, cris:allnoconfig fails to build as follows.
WARNING: modpost: Found 7 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
FATAL: modpost: Section mismatches detected.
Set CONFIG_SECTION_MISMATCH_WARN_ONLY=y to allow them.
Part of the problem is that references from .text to .init.text
are not permitted, and such references are used in cris startup code.
Since references from .head.text to .init.text are permitted, move
cris startup code to a new section .head.text.

The intmem.c code is always built in. It will never be modular,
so using module_init as an alias for __initcall is rather
misleading.
Fix this up now, so that we can relocate module_init from
init.h into module.h in the future. If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.
Direct use of __initcall is discouraged, vs prioritized ones.
Use of device_initcall is consistent with what __initcall
maps onto, and hence does not change the init order, making the
impact of this change zero. Should someone with real hardware
for boot testing want to change it later to arch_initcall or
something different, they can do that at a later date.

Al Viro noted that CRIS fails to handle multiple signals.
This fixes the problem for CRISv32 by making it use a C work_pending
handling loop similar to the ARM implementation in 0a267fa6a15d41c
("ARM: 7472/1: pull all work_pending logics into C function").
This also happens to fixes the warnings which currently trigger on
CRISv32 due to do_signal() being called with interrupts disabled.
Test case (should die of the SIGSEGV which gets raised when setting up
the stack for SIGALRM, but instead reaches and executes the _exit(1)):
#include <unistd.h>
#include <signal.h>
#include <sys/time.h>
#include <err.h>
static void handler(int sig) { }
int main(int argc, char *argv[])
{
int ret;
struct itimerval t1 = { .it_value = {1} };
stack_t ss = {
.ss_sp = NULL,
.ss_size = SIGSTKSZ,
};
struct sigaction action = {
.sa_handler = handler,
.sa_flags = SA_ONSTACK,
};
ret = sigaltstack(&ss, NULL);
if (ret < 0)
err(1, "sigaltstack");
sigaction(SIGALRM, &action, NULL);
setitimer(ITIMER_REAL, &t1, NULL);
pause();
_exit(1);
return 0;
}

Al Viro noted that CRIS is vulnerable to bogus restarts on sigreturn.
The fixes CRISv32 by using regs->exs as an additional indicator to
whether we should attempt to restart the syscall or not. EXS is only
used in the sigtrap handling, and in that path we already have r9 (the
other indicator, which indicates if we're in a syscall or not) cleared.
Test case, a port of Al's ARM version from 653d48b22166db2d8 ("arm: fix
really nasty sigreturn bug"):
#include <unistd.h>
#include <signal.h>
#include <stdlib.h>
#include <sys/time.h>
#include <errno.h>
void f(int n)
{
register int r10 asm ("r10") = n;
__asm__ __volatile__(
"ba 1f \n"
"nop \n"
"break 8 \n"
"1: ba . \n"
"nop \n"
:
: "r" (r10)
: "memory");
}
void handler1(int sig) { }
void handler2(int sig) { raise(1); }
void handler3(int sig) { exit(0); }
int main(int argc, char *argv[])
{
struct sigaction s = {.sa_handler = handler2};
struct itimerval t1 = { .it_value = {1} };
struct itimerval t2 = { .it_value = {2} };
signal(1, handler1);
sigemptyset(&s.sa_mask);
sigaddset(&s.sa_mask, 1);
sigaction(SIGALRM, &s, NULL);
signal(SIGVTALRM, handler3);
setitimer(ITIMER_REAL, &t1, NULL);
setitimer(ITIMER_VIRTUAL, &t2, NULL);
f(-513); /* -ERESTARTNOINTR */
return 0;
}

r9 is used to determine whether syscall restarting must be performed or
not. Unfortunately, r9 is never set to zero in the non-syscall path,
and r9 is on top of that a callee-saved register which can be set to
non-zero by the C functions that are called during IRQ handling.
This means that if r10 (used for the syscall return value) is one of the
-ERESTART* values when a hardware interrupt occurs which leads to a
signal being delivered to the process, the kernel will "restart" a
syscall which never occurred. This will lead to the PC being moved back
by 2 on return to user space.
Fix the problem by setting r9 to zero in the interrupt path.
Test case (should loop forever but ends up executing the break 8 trap
instruction):
#include <signal.h>
#include <stdlib.h>
#include <sys/time.h>
void f(int n)
{
register int r9 asm ("r9") = 1;
register int r10 asm ("r10") = n;
__asm__ __volatile__(
"ba 1f \n"
"nop \n"
"break 8 \n"
"1: ba . \n"
"nop \n"
:
: "r" (r9), "r" (r10)
: "memory");
}
void handler1(int sig) { }
int main(int argc, char *argv[])
{
struct itimerval t1 = { .it_value = {1} };
signal(SIGALRM, handler1);
setitimer(ITIMER_REAL, &t1, NULL);
f(-513); /* -ERESTARTNOINTR */
return 0;

If an attacker can cause a controlled kernel stack overflow, overwriting
the restart block is a very juicy exploit target. This is because the
restart_block is held in the same memory allocation as the kernel stack.
Moving the restart block to struct task_struct prevents this exploit by
making the restart_block harder to locate.
Note that there are other fields in thread_info that are also easy
targets, at least on some architectures.
It's also a decent simplification, since the restart code is more or less
identical on all architectures.

strcmp was lost when all other string functions were removed,
but we still have an optimized version for this on CRISv32,
so any driver built as a module would not have access to this symbol.
In a similar manner, we had optimized versions of
csum_partial_copy_from_user and __do_clear_user
but no exported symbols for them, breaking bunch of other drivers
when built as a module.
At the same time, move EXPORT_SYMBOL(__copy_user) and
EXPORT_SYMBOL(__copy_user_zeroing) C-files so it's
located together with the function definition.
