rhel7-kernel-misery, branch masterAttempts to make the RHEL7 kernel work in minimal CIhttps://git.zx2c4.com/rhel7-kernel-misery/atom/?h=master2020-11-04T09:03:00Zmm: do not assume generic_max_swapfile_size exists2020-11-04T09:03:00ZJason A. DonenfeldJason@zx2c4.com2020-11-04T09:03:00Zurn:sha1:35ffc2a00fe3b8be8ccd9158a88595d9094a6269
For CONFIG_SWAP=n configurations, generic_max_swapfile_size is not
compiled in, so conditionalize this statement.

x86: clear smap in cr4 when not used2020-09-30T14:46:02ZJason A. DonenfeldJason@zx2c4.com2020-06-20T00:07:53Zurn:sha1:f33db22cf6467e06805aec240ced40916c550492
If the CPU supports SMAP, but it isn't specified in the config, then we
need to explicitly clear it from cr4. Otherwise the processor will trap
on all normal userspace accesses, always, since the transition state
isn't being set.

mm: guard pudp_clear_flush_notify with mm notifier config2020-09-30T14:46:02ZJason A. DonenfeldJason@zx2c4.com2020-06-19T23:52:18Zurn:sha1:b5065fe42bae3379cc169a7ebab48805d4dd8eb2
Without CONFIG_MMU_NOTIFIER, pudp_clear_flush_notify isn't defined and
doesn't make sense, so ifdef that out of the huge page path.

x86: remove errant CFI usage from rwlock2020-09-30T14:46:02ZJason A. DonenfeldJason@zx2c4.com2020-05-25T03:25:28Zurn:sha1:1013aca961d8dd47191b4371da95a26ccfb60689
These don't assemble with newer binutils due to the use of the cfi
directives, so simply remove them, since they're anyway just for
debugging.

Without marking this as static, the linker complaints about conflicts.

Don't call into fib_encap_match when it's not defined on
!CONFIG_IP_ROUTE_MULTIPATH kernels.
