Linus Torvalds 7c0f6ba682 Replace <asm/uaccess.h> with <linux/uaccess.h> globally
This was entirely automated, using the script by Al:

  PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*<asm/uaccess.h>'
  sed -i -e "s!$PATT!#include <linux/uaccess.h>!" \
        $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h)

to do the replacement at the end of the merge window.

Mauro Carvalho Chehab 6634fbb6b6 driver-api: create an edac.rst file with EDAC documentation
Currently, there's no device driver documentation for the EDAC
subsystem at the driver-api book. Fill in the blanks for the
structures and functions that misses documentation, uniform
the word on the existing ones, and add a new edac.rst file at
driver-api, in order to document the EDAC subsystem.

Yazen Ghannam a884675b87 x86/MCE/AMD, EDAC: Handle reserved bank 4 on Fam17h properly
Bank 4 is reserved on family 0x17 and shouldn't generate any MCE
records. However, broken hardware and software is not something unheard
of so warn about bank 4 errors. They shouldn't be coming from bank 4
naturally but users can still use mce_amd_inj to simulate errors from it
for testing purposed.

Also, avoid special handling in the injector mce_amd_inj like it is
being done on the older families.

Scalable MCA defines a number of IP types. An MCA bank on an SMCA
system is defined as one of these IP types. A bank's type is uniquely
identified by the combination of the HWID and MCATYPE values read from
its MCA_IPID register.

Add the required tables in order to be able to lookup error descriptions
based on a bank's type and the error's extended error code.
