The TIS interrupt handler at least has to read and write the interrupt
status register. In case of SPI both operations result in a call to
tpm_tis_spi_transfer() which uses the bus_lock_mutex of the spi device
and thus must only be called from a sleepable context.

To ensure this request a threaded interrupt handler.

Implement a usage counter for the (default) locality used by the TPM TIS
driver:
Request the locality from the TPM if it has not been claimed yet, otherwise
only increment the counter. Also release the locality if the counter is 0
otherwise only decrement the counter. Since in case of SPI the register
accesses are locked by means of the SPI bus mutex use a sleepable lock
(i.e. also a mutex) to ensure thread-safety of the counter which may be
accessed by both a userspace thread and the interrupt handler.

By doing this refactor the names of the amended functions to use a more
appropriate prefix.

After driver initialization tpm_tis_data->locality may only be modified in
case of a LOCALITY CHANGE interrupt. In this case the interrupt handler
iterates over all localities only to assign the active one to
tpm_tis_data->locality.

However this information is never used any more, so the assignment is not
needed.
Furthermore without the assignment tpm_tis_data->locality cannot change any
more at driver runtime, and thus no protection against concurrent
modification is required when the variable is read at other places.

So remove this iteration entirely.

The interrupt handler that sets the boolean variable irq_tested may run on
another CPU as the thread that checks irq_tested as part of the irq test in
tpm_tis_send().

Since nothing guarantees cache coherency between CPUs for unsynchronized
accesses to boolean variables the testing thread might not perceive the
value change done in the interrupt handler.

Avoid this issue by setting the bit TPM_TIS_IRQ_TESTED in the flags field
of the tpm_tis_data struct and by accessing this field with the bit
manipulating functions that provide cache coherency.

Also convert all other existing sites to use the proper macros when
accessing this bitfield.

signing keys used for signature verification.

When no restrictions are selected, all Machine Owner Keys (MOK) are added
to the machine keyring.  When CONFIG_INTEGRITY_CA_MACHINE_KEYRING is
selected, the CA bit must be true.  Also the key usage must contain
keyCertSign, any other usage field may be set as well.

We started disabling '-Warray-bounds' for gcc-12 originally on s390,
because it resulted in some warnings that weren't realistically fixable
(commit 8b202ee2: "s390: disable -Warray-bounds").

That s390-specific issue was then found to be less common elsewhere, but
generic (see f0be87c4: "gcc-12: disable '-Warray-bounds' universally
for now"), and then later expanded the version check was expanded to
gcc-11 (5a41237a: "gcc: disable -Warray-bounds for gcc-11 too").

And it turns out that I was much too optimistic in thinking that it's
all going to go away, and here we are with gcc-13 showing all the same
issues.  So instead of expanding this one version at a time, let's just
disable it for gcc-11+, and put an end limit to it only when we actually
find a solution.

Yes, I'm sure some of this is because the kernel just does odd things
(like our "container_of()" use, but also knowingly playing games with
things like linker tables and array layouts).

And yes, some of the warnings are likely signs of real bugs, but when
there are hundreds of false positives, that doesn't really help.

You need to strip two suffixes from compressed tarballs and one suffix

One tricky fix might be --prefix=$(firstword $(subst .tar, ,$@))/
