vexpress: Move setting master site to vexpress-config bus

There's only a single caller of vexpress_config_set_master() from
vexpress-sysreg.c. Let's just make the registers needed available to
vexpress-config and move all the code there. The registers needed aren't
used anywhere else either. With this, we can get rid of the private API
between these 2 drivers.

bus: vexpress-config: simplify config bus probing

The vexpress-config initialization is dependent on the vexpress-syscfg
driver probing. As vexpress-config was not a driver, deferred probe
could not be used and instead initcall ordering was relied upon. This is
fragile and doesn't work for modules.

Let's move the config bus init into the vexpress-syscfg probe. This
eliminates the initcall ordering requirement and the need to create a
struct device and the "vexpress-config" class.

arm64: vexpress: Don't select CONFIG_POWER_RESET_VEXPRESS

The VExpress power-off/reset driver is not needed on 64-bit platforms as
PSCI power-off and reset can be used instead. Stop selecting it so it
can be disabled and not always built-in.

CONFIG_VEXPRESS_CONFIG can also be dropped as it was a dependency for
CONFIG_POWER_RESET_VEXPRESS.

ARM: vexpress: Move vexpress_flags_set() into arch code

vexpress_flags_set() is only used by the platform SMP related code and
has nothing to do with the vexpress-sysreg MFD driver other than both
access the same h/w block. It's also only needed for 32-bit systems and
must be built-in for them. Let's move vexpress_flags_set() closer to
where it is being used. This will allow for vexpress-sysreg to be built
as a module.

arm64: vdso: Add -fasynchronous-unwind-tables to cflags

On arm64 linux gcc uses -fasynchronous-unwind-tables -funwind-tables
by default since gcc-8, so now the de facto platform ABI is to allow
unwinding from async signal handlers.

However on bare metal targets (aarch64-none-elf), and on old gcc,
async and sync unwind tables are not enabled by default to avoid
runtime memory costs.

This means if linux is built with a baremetal toolchain the vdso.so
may not have unwind tables which breaks the gcc platform ABI guarantee
in userspace.

Add -fasynchronous-unwind-tables explicitly to the vgettimeofday.o
cflags to address the ABI change.

block: remove the bd_openers checks in blk_drop_partitions

When replacing the bd_super check with a bd_openers I followed a logical
conclusion, which turns out to be utterly wrong.  When a block device has
bd_super sets it has a mount file system on it (although not every
mounted file system sets bd_super), but that also implies it doesn't even
have partitions to start with.

4 years agofibmap: Warn and return an error in case of block > INT_MAX

fibmap: Warn and return an error in case of block > INT_MAX

We better warn the fibmap user and not return a truncated and therefore
an incorrect block map address if the bmap() returned block address
is greater than INT_MAX (since user supplied integer pointer).

It's better to pr_warn() all user of ioctl_fibmap() and return a proper
error code rather than silently letting a FS corruption happen if the
user tries to fiddle around with the returned block map address.

We fix this by returning an error code of -ERANGE and returning 0 as the
block mapping address in case if it is > INT_MAX.

Now iomap_bmap() could be called from either of these two paths.
Either when a user is calling an ioctl_fibmap() interface to get
the block mapping address or by some filesystem via use of bmap()
internal kernel API.
bmap() kernel API is well equipped with handling of u64 addresses.

WARN condition in iomap_bmap_actor() was mainly added to warn all
the fibmap users. But now that we have directly added this warning
for all fibmap users and also made sure to return 0 as block map address
in case if addr > INT_MAX.
So we can now remove this logic from iomap_bmap_actor().
